35. Added code to show layers when viewing GOCAD 3D vector files.36. New Surface & Transparency tabs added to the 3D vector properties37. Improved support for Datamine string/perimeter files.38. Removed colour axis concept and automatic colour annotations.39. Changed the Drag Drop query dialog for geosoft databases. It now

uses a less confusing dialog with a simple question dependent onhow many gdb files have been dropped. If 1 file dopped then it

queries whether the file is a normal geosoft database or Geosoftdownhole before OASIS V4.2. If multiple files are dropped then itqueries whether the file are all normal geosoft databases orGeosoft downhole after OASIS V4.2 dataset.

40. Two additional methods of bitmap capture in the fly through wizardAVI creation process:'Normal' capture mode is the original mode. This mode is safe buthas the key disadvantages that it is slow, uses memory and does notrender tiled EGB surfaces correctly.'Advanced' capture mode resizes the view to suit the output


14/28

resolution of the AVI and by doing so can directly capture thegraphics buffer to create each image. This overcomes all thedisadvantages of the 'Normal' mode but requires the view to be inmaximised and in 'fast mode'.'Expert' mode is significantly faster than the other two modes butbecause it directly captures the bitmap from the screen. If anywindow is overlapping the source window then it will be capturedin the AVI. Your AVI output size is limited to the size of thescreen or less.

41. EGB series now supports ERMapper .ecw and .alg files, includingDrag and Drop support.

42. DXF output now supported with AutoCAD 2006 (Solid Generator,Extrusion Wizard, Feature Export, Transform Vector File, CombineDXFs)

43. Statistics Explorer now requests confirmation from the user beforeplotting graphs containing more than 250000 points.

44. Improved About information boxes for all Plug_In tools.45. Removed Surface Compression Options from Options dialog.46. Added support to Legend Editor for Feature Databases.

Defects1. Only the standard pop-up menu is displayed in the 3D View.2. Removed symbol size units control from lines and points series.

3. Text depth alignment now works in 3D.4. Text size blocking and clamping now works in 3D.5. The pinned dialog would constantly reposition itself on multiple

monitor systems.6. Changing dataset source in drillholes caused a crash.7. Changing some drillhole properties reset the colour stretch.8. Changing the font in drillholes was resetting the text angle.9. Symbol fill and line colour was not supported for vector symbols in

drillholes.10. Changing the drillhole dataset did not reset the field lists in all

property pages.11. Changing drillhole thicknesses caused the graphics to display

incorrectly.

12. Fixed the Apply button dismissing the pinned dialog for drillholes.13. Drillholes in workspace tree showed source data string.14. Symbol size selector often reported the wrong size.15. Removed references to size axis floating colour scales.16. Discover3D now switches to fast view and forces focus to be on the

3D plot.17. Drillhole label manual rotation was not working.18. Built-in vector symbols were not rendered using a display list in

many cases.19. Lat/long DTM grid surfaces rendered using variable compression

could show height gaps.20. Select mode is enabled correctly when closing the cursor plane.

This was sometimes making it so the view would not rotate even

though it appeared to be select\navigate mode. When a property pageis open do not update the property pages connected object whenclicking on a view. This stops the problem of the property pagesgoing to the 3D map object when click on the view to rotate.

21. When closing down the application if there was unsaved data and the"Save session" message box appeared, the user could cancel theclose by clicking "Cancel" on the message box. A side effect ofthis was that the workspace tree view was already deleted andtherefore appeared blank. It could not get restored unless a closeall was issued.


15/28

22. When editing a workspace tree item, if the delete key was pressedthen the complete item would be deleted from the tree.

23. Fixed problem with the "Save To Package" command not copying somefiles in a complex document.

24. Fixed crash when trying to load 16 bit goetiffs.25. When multiple databases were loaded random crashes could occur.26. Fixed a problem with the view scaling if the user turned off

a series that covered a large area of the view via the workspacetree.

27. If you added a drillhole object with no data loaded, when theproperty pages were opened the application would crash.

28. Loading a session that containing a 3D vector file that had beenhidden when saving, on reloading the session the name of theobject in the workspace tree would be missing.

29. Fixed a problem when trying to load tab rasters that referenceda large jpg file.

30. When repathing the temp files for a D3D session, attempting tocopy the file if the source and destination files are in the samedirectory produced a system error message box.

31. Added 'Local' lighting mode to EGB surfaces properties.32. Added one sided and two sided lighting control to EGB files.33. Added local and infinite viewpoint lighting controls to EGB files.34. Added mesh scope lighting override to EGB files.35. Fixed some interaction/rendering Defects between lighting and smooth

shading modes in EGB rendering.36. Vector files will now generally render wih smooth shading bydefault.

37. Lighting and shading mode could 'bleed' from one mesh to others asit was not being restored to the group default.

38. Cleared the undo/redo buffer after the creation of the intialdocument.

39. Fixed a memory leak with ECW surfaces in a Grid Group.40. ECW images were mislocated if they required an offset in the view.41. If trying to delete a 2D vector from the workspace via the

'delete' key then D3D would crash. Also when trying to select thisnode in the tree it would jump to the root node most of the time.

42. With 2 or more datasets open, the size modulation controls for 3D

symbols on the properties pages didn't seem to adjust to thecorrect dataset chosen by the user.43. EGB series could leak a large amount of memory when deleted or

reloaded because of a failure to clean up allocated texture memory.44. After deleting a the last object in a 3D view the view would seem

to freeze and still display the last object.45. If trying to delete a 3D axis or 3D vector file from the workspace

via the 'delete' key then D3D would crash.46. Status bar messages were missing for the following menu items:

- File->Close Datasets- File->Save View As- File->Save To Package- View->Toolbars->Save Arrangement

- View->Toolbars->Restore Arrangement- View->Toolbars->Reset Arrangement- Insert->2D Vector

47. 'Render Text' option for 2D vector files was not being saved in thesession files.

48. Transparent isosurfaces with 'no self see through' turned OFF willnow render correctly (using back sorting). Rendering performance isreduced. 'No self see through' is now turned OFF by default.

49. Contour dropout was working unreliably.50. Isosurface colour modulation could crash in some circumstances.


16/28

51. Voxel models always rebuilt their complete display lists whenleaving the property pages, or was dragging a slice through themodel with auto apply turned on. This bug meant that when certainDXF files were loaded nothing could be seen until a "zoom toextents" command was issued, and even then the 3D axis was notshown at the same location as the DXF data.

52. When objects are added to the workspace tree, they now get addedto the branch immediately after the last item in the tree of itssame type. If there are no items of the same type in the tree thengets added after any existing annotations as before.

53. Colour mapping in EGB series was failing when series were scaled/translated in some circumstances.

54. If a session was closed down that had previously had a fly throughplaying/avi saving, reopening the session and stepping through

the Fly Through Wizard, then moving from the "Path" page to the"Output"page would result in the wizard issuing a message boxsaying "Server threw exception". This has now been fixed.

55. When creating AVI's for a fly through or sometimes just playing afly through, sometimes objects would not render the change of statewhen properties of the fly through were turned on or off.

56. Properties also reset correctly now when a fly through is finishedor the user presses the "stop" button on the flight control slider.

57. Scaling a 3D vector file by a negative value then the 3D vectorfile would disappear from the view and any visible 3D axes would go

haywire.58. Displaying fast symbols with labels and disabling the rendering ofsome symbols using transparency defined from a legend, the labelswere still displayed at the symbol position.

59. When surfaces are displayed with tiled textures the tile boundariesused to be seen as thin light grey lines. On graphics cards thatsupport texture edge clamping this has now been eliminated.

60. When displaying a ECW, zooming into data close enough withtransparency set to 100% would result in all data in the viewdisappearing.

61. Reading 64 bit (double precision) binary Surfer grids wasoffsetting by one cell (8 bytes) and introducing an invalid cell atthe origin.

62. Using the export wizard for voxel models could cause a crash.63. Drag and dropping .gdb file would crash.64. If a drillhole began at something other than zero depth, image

curtains could be mislocated downhole.65. Fixed EGB hit testing to include scaling factors.66. Fixed EGB hit testing to improve the granularity of the spatial

search structure.67. Fixed EGB hit testing where an incorrect hit could result from

inappropriate testing termination.68. Image Registration Wizard would not allow the user to enter values

that contained a decimal place. As soon as the decimal point wastyped the cursor would move to the front of the number and nodecimal point would appear.

69. Data panning was not working properly in smooth pan mode.70. Data zoom in/out on a single click was too large.71. Point size control was incorrectly disabled.72. Removed Frame Properties dialog.73. Deleting an object from the workspace tree using the delete key was

not updating the view correctly and therefore giving an incorrectdata range for the remaining objects.

74. Stopped an extra application button appearing in the taskbar aftergoing into full screen mode.

75. If the application was moved to a different monitor and "Use


17/28

current display settings" was selected for the fullscreen options,then the display resolution may be invalid for that monitor.

======================================================================

Encom Discover 3D v2.00Version 2.0.14 Released July 2005.

======================================================================

New Features1. Added advanced COM support for voxel model property controls. TAB

dataset import now treats multi-vertex features as new lines (if a

line field has been identified).2. Added a new feature that allows you to select the shape of a 3Dtube. Accessed via the '3D Line Style' property page.

3. Auto Apply added to all Drill hole and Curve property pages.4. When in 3D navigate mode the position of 3D origin axis will be

displayed on the status when the 3D origin is shown.5. A new feature batch hardcopy wizard has been added to allow users

to export plots to either image files or the printer when using thefeature batch print method.

6. Scrolling the Mouse Wheel will now zoom a 3D view in and out.7. All unused datasets are closed now whenever a session is saved.

Previously all open datasets were referenced in the session.8. All property pages that contain drop down list boxes for Lookup

Tables and Legends will now distinguish where the table resides(i.e. in the project folder or the system folder).9. Added new file search ability to EGB grid file references. These

are exported with a relative path so if the EGB is moved the pathmay become invalid. PA assumes that if it is moved it is likely tobe to a deeper directory. Therefore it looks back up the directorytree for the grid file in a shallower path. It fails to find thefile the find lost file mechanism will then activate to locate thefile.

10. Added support for Arc Ascii grid format.11. Added Packager support to the File menu. The packager allows the

user to centrally store all external files used by a session.12. Added the file loading report dialog that pops up at the end of

loading a session if any files could not be located or were autoreplaced by the find lost file facility. Showing of this reportcan be turned on or off via the Tools->Options->File property page.It can also be turned off from the report dialog itself.

13. Added native support for located images GeoTiff and raster TABfiles via the located image series. This provides an efficientmechanism to display these images.

14. GEMCOM 3D vector file support added.15. Noddy voxel model support added.16. Voxel model information report added.


22/28

17. Automatic modified file updating added.18. Voxel model export in UBC format added.19. BIL raster format support added.20. Geosoft compressed raster support added.21. A new fly through creation wizard enables you to record a fly

through to an AVI video file or to generate a script that, whendropped into a 3D view, will execute a fly through interactively.

Any video codec installed on the system can be used to create theAVI file, although MPEG4 is highly recommended. Synthetic speechor WAV audio files can be incorporated into the fly through scriptto provide audio cues throughout the fly through (not available inthe AVI).

The fly through flight path can be generated interactively inDiscover3D or by drawing from various data sources includingMapinfo TAB files or any dataset loaded in Discover3D. The finalflight path can be exported as a 3D DXF for display in the 3D view.

22. 2D vector formats are now supported in 3D graphs and maps.23. Added ECW support for Surfaces.24. Added sensitivity control when flying around the 3D view. Use the

number keys to change the sensitivity :a. 0 = default speedb. 1 to 9 (Slowest to default)

25. Added an Explorer View Window to the Information Sheet.26. The Number Format Dialog now contains the ability to allow theuser to select a Locale to use to define the 1000's separatorcharacter and the decimal point character when formatting a numberfor a label.

Improved Features1. 3D Performance improved by preventing series regeneration when

adding or deleting 3D annotations, and when deleting all series notderived from curves.

2. 3D vector file optimisations when turning on/off separate blocks3. 3D vector file smoothing performance improved.

4. Added ability to drag and drop ERMapper ALG files.5. Added better handling of dialog and property page edit boxes thatuse floating point values. You can now enter a '.' and not receivemessage boxes requesting you to enter a number.

6. Added default colour selector to 3D Map properties that allows theuser to set the default font colours for both light and darkbackgrounds. These values are used as the default colours when anew series created. They are also used if the user changes thebackground colour. These colours are accessed via the "Advanced"button on the 3D Map->Appearance properties page.

7. Added support for Arc Binary grids.8. Added support for data mapped colour look up tables in the voxel

model series. If you load a data mapped LUT then the data map will

be used automatically. Data mapped LUT's can be identified in thedrop down list by a unique icon.

9. Added support for optional TFW files when loading GeoTIFF files.10. Added XY offset variables to voxel models.11. Auto Apply added to all Drill hole property pages.12. Automatic updating now checks for colour LUT and legend file

changes.13. Decimation has been added as a 3D grid compression option.14. Disabled pointless warning messages which are displayed when

loading TIFF images and grids.


23/28

15. EGB files now clip the geometry to the image extents.16. EGB images displayed in 3D now load the bitmaps on demand and

unload them as soon as they have been converted to textures. Thiswill keep memory use minimised. Also a possible texture memoryleak has been closed. Also, when an image is turned off from thetree (or a drill hole is switched off) the image and texturememory is unloaded.

17. EGB surfaces that use grids now unload/load this data on demand.18. ERMapper raster file support improved.19. If a LUT file is unlocated then the system will only report the

error once on loading the session.20. If a raster grid has been decimated during import the original

size of the grid is shown in brackets in the grid informationdialog. Information is also given about the NULL value and numberof NULL grid cells.

21. If an EGB file is unlocated or an image file referenced by theEGB is lost the system will only report an error once.

22. Improved drill hole EGB curtain widths and scaling. The widthcan now be defined in the EGB file and scaling control is morepowerful.

23. Improved grid compression controls and options.24. Improved integration with the LUT and Legend editors.25. Improved numeric accuracy of output ERMapper grid file header.26. Increased maximum line length in DXF files.

27. Look-at point now remains a constant size as you zoom in and out.28. Made some savings in memory consumption for EGB files that usegrids.

29. Modified drill hole EGB coordinate calculation so that thecurtain is always perpendicular to the hole locally. Note thatthis can cause some overlap of the image.

30. Moved label anchor position from 3D symbols as they didn't work.31. Optimised 3D rendering code in navigate mode.32. Removed coordinates from EGB serialisation which can reduce the

size of sessions/templates/components and also clipboard data.33. Removed some data duplication in EGB files to minimise memory

use. This particularly improves the memory use of EGB files thatrefer to external grids as the surface geometry source.

34. Restricted the compression slider in EGB files from 30 - 100% sothat users cannot set compression at less than 30% via the GUI.This is to ensure a reasonable level of compression is alwaysachieved and to prevent memory and CPU blowouts.

35. Restricted the compression slider in Image (Surface) files from 30- 100% so that users cannot set compression at less than 30% viathe GUI. This is to ensure a reasonable level of compression isalways achieved and to prevent memory and CPU blowouts.

36. Standardised the way in which lost files are relayed to the user.The full path and name of the file will be shown in the title ofthe File Selector dialog which can be resized to view the entirename if need be. It will also be shown in the status bar whilstthe dialog is open.

37. Streamlined the settings for axis arrangement in floating axes.38. Support for surfaces in EGB files improved.39. The auto reset of the view transform now has a larger range

before it gets triggered.40. The directory a session is loaded from will now be guaranteed to

be the first path searched when looking for lost files.41. The Located Image->Offset page now has some new transform options.

You can scale the Z value, offset the X,Y and Z values, or use aDTM to specify the values.

42. The shadow scaling in the grid image pseudocolour intensity layer


24/28

and the RGB intensity layer is now computed using a more robusttechnique. All existing sessions, templates and components willlose their user shadow scaling factors when reloaded. It will bereset to default. Thereafter, it can be modified and resaved. Thisfixes problems we have seems with latitude/longitude grids andwith grids that have very low or extremely high dynamic ranges.

43. The voxel model information report now takes into account anyclipping of the model when computing the volume of the model andof thresholds and lithology thresholds.

44. Tool tips are now created for any dynamically created toolbarsspecified in the .etm files.

45. Upgraded 3D surface compression to support decimation and nocompression. Supported various decimation options.

46. Users can now control the size of critical 3D textures.47. Voxel model optimisations when modifying certain objects such as

Slices, Isosurfaces, and thresholds.48. When in 3D navigate mode the position of 3D origin axis will be

displayed on the status when the 3D origin is shown.49. When loading an EGB, the path to the EGB is now added to the find

lost file mechanism so any fully qualified sub files of the EGBwill be located if they are dropped into the same directory as theEGB.

50. When you turn on slices for a voxel model, only one slice willinitially appear.

51. Surface Property page improvements:* Added the ability to see the name of the selected surface in thetree view of the imager properties pages.

* Added companion edit boxes to go with the Scale and Offsetsliders in the Surface Layer Property Page for Imager objects.

* Grids list can now been seen on the Surface page as well as thelayer page.

52. The graphical drill hole selection dialog has been improved in anumber of ways.* New control layout* Added status bar to show world coordinates that the mousepointer is at when moving around the graphical view.

* Added a new view control that can switch the way drill holes are

selected, that is you can now select holes using the XP Plane(Top view), XZ Plane (front view) and the YZ Plane (side view).* View mode saved between instances.

Defects* 3D compass was not displaying properly when a 2D vector file wasdisplayed in a 3D view.

* 3D text size is now related to screen percentage. 1pt = 0.4% screen.* After saving a view to file, copying to the clipboard or generatingan AVI, EGB files would be corrupted.

* Any view with a textured surface in it would render slowly.* Auto updating now detects changes to legend files.

* Axis scale property pages reported the wrong information is someinstances.

* Colour Lookup Table Editor and Legend Editor were displaying anderror message if the user tried to "edit" a file that has a spacein its path name.

* Colour LUT files of the same name from different search paths werebeing rejected. Now retained with a modified name.

* Colour LUT files were not being properly searched for on disk afterdeserialisation.

* Colour modulation switch and adding/deleting bands from the


25/28

workspace tree is more tightly integrated.* Colour tables were not read properly in certain circumstances wheninterpolation was set to HSL.

* Computation of the view data space range was including series whichhad been switched off. The view transform was not being reset asrequired.

* Contours were not regenerating when loaded in a session.* Corrected location where ERS files are rendered.* Crash occurred if the LUT editor was closed after closing theproperty page that invoked it.

* Crash occurred if the system template file did not exist or was nota valid template.

* Display a drill hole, then all holes, and then switch on colourmodulation. Would crash.

* Displaying drill hole data had a number of Defects that affected thedisplay such as appropriate colour/legend modulation etc. These wereonly seen in certain circumstances.

* Drag and drop improved with expanded file type support, targeting asingle document when multiple files are dropped and targeting asingle grid image series when multiple files are dropped.

* Drill hole datasets that contained a single station could causeDisc3D to throw an exception when loading. Also, the desurveying forholes with only one station was failing.

* Drill holes were not rendering cleanly due to floating point

round-off errors.* EGB files were not performing properly when saving a bitmap on thescreen or when rendered in an AVI. Performance of AVI generation wasalso being compromised by EGB files.

* EGB files with grids were broken.* Fast symbol sizes are now closer to normal symbol sizes.* Filled symbols were not rendering properly in 3D.* Fixed a problem where the workspace tree would unexpectedly expandsome nodes after modifying some property page.

* Fixed a problem which caused grids to be loaded when not needed inVoxel and EGB series.

* Fixed a problem with filenames in the startup.etm files containinghyphens in the directory names. On some machines the tool would not

be added.* Fixed colour space and crashing problems associated with some PNGfiles.

* Fixed coordinate round-off problem in blocks of DXF files.* Fixed minor bug in Vertical Mapper grid support.* Fixed problem with Datamine voxel model cell sizes.* Fixed problems with miss-location of EGB curtains on drill holes.Implemented support for texture coordinates in these EGB files.

* Fixed the problem with the SHARE.exe message box popping up.* Fixed TIFF read/write support.* Fixed up block handling for 2D and 3D DXF files so that any numberof blocks can now be handled. (Previously there was a limit of about2000 blocks due to the use of temp files for blocks. File offsets

within the original DXF file are now used instead).* Geosoft wholeplot (later version) survey database group name wasbeing set to the file name but some parts of the code assume it iscalled "Survey". Now we always set the Collar group name to Collarand Survey group name to Survey. Also, the survey file was not beingrecognised if the filename was not "Survey". We still require thesurvey file to have "Survey" in the filename.

* Graph initial colour table property page was inactive.* Grid name in image series tree was not set correctly when a grid wasloaded via a plug-in.


26/28

* Grid rendering performance was compromised by texture mapping andgrid normals were incorrectly calculated.

* HSL colour interpolation was not working.* If "Auto Apply" was turned on for a Lines->Symbol property page thenwhen turning on modulate colour it would automatically turn itselfback off.

* If a multi-element EGB series had some elements turned off thosesettings were not preserved in serialisation or when copying thatobject.

* If a voxel model was using a legend or colour lookup table and thecolour table got modified, the voxel model was not auto updatingwith the new colour scale.

* If an offset was applied to an EGB file that used bitmaporigin/extremity coordinates the bitmap was not offset with thegeometry.

* If displaying two or more objects in 3D view and you then deletedone of the objects, the view extents appeared to be taking intoconsideration the deleted object until a property in any of theremaining objects was modified and then the view would appear tojump to the correct extents.

* If no EGB file name is specified at the end of the wizard itautomatically opens the File Save As... Dialog to obtain one.

* If you changed the band in the surface properties then itsattributes were not being passed to the children layers.

* If you try to display depth labels on a drill hole that does notcome from a drill hole database it would crash or behave poorly.* iHelp jumped to a new page when changing tabs via a ShowMe call.* iHelp jumped to unexpected page if property page had no iHelp page.* Image processing engine was sometimes rendering grids as verticallystriped images. Also, it was incorrectly using interpolation in somecases when it was not required, impacting on rendering performance.

* Improved code which renders DXF files containing polyface Meshpolylines. Previously the wrong bounded box was being computed whichmeant nothing was displayed.

* Legend files failed to load entries where the data type was text andthe text item was an empty string.

* Legends were drawn upside down in some colour property pages.

* Lighting on EGB surfaces was not correctly initialised when firstswitched on.* Loaded sessions were having their saved Eye and Lookat positionsreset and therefore the view was different to what the user saved itas.

* Loading datasets across a network drive that was not mapped wasfailing.

* Logarithmic contour scales were not being correctly generated.* Memory leaks fixed in the feature database.* Mouse middle button navigation in 3D was not terminating when yourelease the mouse button.

* Multi-banded voxel models were not rendering correctly and were onlydisplaying the set of valid cells rather than the valid cells for

each band.* Objects can no longer be inverted by dragging back on themselves.* On the Image->Advanced property page the "Clip recursively" and"Clip on edge only" controls were not being set correctly afterclicking on "ok" or "apply" for the property page.

* Polygons from 2D DXF vector files rendered as 2D in 3D views werenot closed properly and would not render in all cases.

* Problems displaying RGB images.* Problems scaling series.* Redrawing efficiency was improved for complicated documents when


27/28

using selections.* Removed label anchor position from 3D symbols as they didn't work.* Rendering of bendy tubes was failing when there were equal points onthe tube. This was caused by a fix for a bug for NULL pointrendering made a few weeks ago.

* Sections were not displaying on demand in 3D. It would often requirechanging something else to make the section appear.

* Sessions that saved views in fast mode were not restoring back intofast mode.

* Some of the voxel model formats were not closing their input file(s)after loading the files. This prevented any other application orprocess from using the file(s).

* Surface textures were not rendered in layout mode if the surfacewas constructed in fast view.

* Symbol size units are not used in 3D and have been removed. Otherchanges to the property page to remove invalid options in differentstates have been made.

* Symbols were being stretched when axes were scaled anisotropically.* Text offset factors have been fixed - 1 unit = 0.1% of the screen.* The 3D compass was being drawn when printing.* The accuracy of the information reported in the data tab of theiHelp window has been improved.

* The Colour Scale dialog that could be accessed via the voxel modelproperty pages was not handling last loaded legends correctly.

* The DTM Z offset for 2D vector files in 3D maps was not working -there were user interface issues as well as its failure to apply thegrid offset.

* The Grid directory was not being remembered when loading Algorithmsor ECW's via the Surface Wizard button.

* The properties displayed in the document were not being saved intosessions and templates.

* The XY pixel size of EGB files for export was not being honoured.* There was a problem with the auto update of a surface. If thesurface was using different grids for different layers then duringan auto update if one of the grids was modified then all layers wereset to the same grid. In some instances linked cursors were notoperating from profiles to maps. This was because the first and/or

last stations in the line had NULL X or Y values.* There was no warning or find lost file routine if a grid which wasreferenced from inside an EGB could not be found.

* There were a number of obscure and generally unseen Defects in therecord set construction code for drill holes. There was also arendering bug in the drill hole tube rendering algorithm thatinserted gaps into the hole (interpreted as nulls). Rendering acrossnulls in this situation may have misrepresented the data in somecases.

* TIFF import/export fixed.* Transparency slider on surfaces was not updating correctly.* Transparent colour ranges were not being set correctly when comingthrough the COM interface.

* Transparent object rendering Defects addressed.* UBC voxel import failed to read files with cell sizes split overmultiple lines.

* Voxel isosurface transparency slider was not functioning.* Voxel model report was confusing length and height. Reportformatting was improved.

* Voxel model was returning mixed up Y and Z coordinate ranges whenoffsets were applied. This led to problems with the 3D annotationsand view transforms.

* Voxel models that do not store the NULL value locally in the file


28/28

were not deserialising correctly.* We discovered that geosoft wholeplot databases have changed formatat some stage in the past. Whilst the desurveyed XYZ coordinates foreach sample used to be computed and stored as the top of the sampleit now seems they are the centre of the sample. We now desurvey allgeosoft wholeplot data and recompute the XYZ coordinates. Thisinformation is not written back into the database - it is computedeach time the database is opened.

* When a new colour table selection was made the appropriate table wasnot reflected in the property page and the change was sometimes lost.

* When axes are switched off/on, the auto arrangement algorithm movedthem to suit the new arrangement of displayed axes. This wasundesirable and not the intention of the user.

* When loading drill hole databases insufficient attention was paid toNULL or EMPTY fields in the collar and survey fields. In some casesthis could lead to holes failing to display because - for example -the survey data was not recorded in the database.
