PERFORMANCE

• Pixel Threshold

• Defines a N x N pixel square

• N = Threshold

• Entities that fit inside the pixel square are acted on

• Entities are any geometry/text

• Solids

• Faces

• Edges

• Wireframe

• Etc.

• Culling

• Replacing the display of entities with a dot

N = 10


PERFORMANCE

• Pixel Threshold –

(Cont’d.)

• To get a “feel” for pixel size on a screen

– Convert pixels to inches • Pixels ÷ DPI = Inches

– Pixels = threshold

– DPI = Dots per inch

– Screen resolution = 1920x1200

– DPI = 1920 ÷ screen width inches

N = 10

Diagonal

?


PERFORMANCE

• Pixel Threshold – (Cont’d.)

• To get a “feel” for pixel size on a screen

– Pixels per inches (PPI) (Dots per inch –

DPI)

• Screen resolution = 1920x1200

• Diagonal = 17 inches

• Pixel threshold = 10

– Get sum of the squares of screen resolution

1920^2 +1200^2 = 5,126,400

– Take square root of sum

√ 5,126,400 = 2,264

– Divide by diagonal to get PPI

2.264/17 = 133.2 PPI (generic 120DPI)

– Divide threshold by PPI to get threshold inch size

10/ 133.2 = .08”

N = 10

Diagonal

?


PERFORMANCE

• Pixel Threshold – (Cont’d.)

• Use this base value to estimate threshold values that will work for you

• N=10 ~ .08”

• N=20 ~ .08” * 2 =.16

• …

• N=50 ~ .08” * 5 =.4

N = ?

• Stops drawing “small” True Type font text

• Show a simple box at text location

• Uses pixels to determine text size at current zoom, rotation, etc.

• Range: 1 100 Default= 5

Smaller text size not

displayedLarger text size not

displayed


PERFORMANCE

• Simplify Text – (Cont’d.)

• When not selected

• Draws complete text regardless of size at every required redraw

• Benefits

• Redraw completes faster

• Faster dynamics

• Small text probably not legible any way


PERFORMANCE

• Framerate Optimization Methods

• None

• Redraws everything before update completes

• Benefits

• How previous KC versions display redraw worked


PERFORMANCE

• Framerate Optimization Methods –(Cont’d.)

• Display Culling

• Displays only geometry that is larger than threshold during:

• Zooming

• Dynamic rotations

• Panning


PERFORMANCE


• Culling threshold when not rotating…

• Does not display geometry that falls within the pixel threshold at current viewport state

• The more zoomed out the less geometry might be displayed

• Range: 1 200 Default = 3

No Culling Culling



displayed


PERFORMANCE


• Culling threshold when rotating…

• Does not display geometry that falls within the pixel threshold during dynamic rotation, zooming & panning

• The more zoomed out the less geometry might be displayed during dynamic rotation

• Range: 1 200 Default = 5



displayed


PERFORMANCE


• Benefits

• Faster redraw by eliminating geometry too small to deal with at that particular viewport status

• Faster redraw during dynamics

• Faster dynamics

• Uses less graphics resources


PERFORMANCE


• Minimum number of frames per second…– Fixed frame rate option will produce at least the given number of

frames per second in non-hidden-line rendering modes

• Minimum number of frames…

• Stops drawing after the given time, then uses idle time to continue drawing in increments until the scene is complete (draws when KeyCreator isn't doing anything else).

• Drawing starts over when the scene changes (pan/zoom/rotate, or entities created/modified/deleted).

• Range: 1 30

• Default = 15

More time to draw – More

entities drawn - Rougher

dynamic movement

Less time to draw – Fewer

entities drawn - Smoother

dynamic movement


PERFORMANCE

• Framerate Optimization Methods – (Cont’d.)

• Culling Threshold for deferring entities…

• Draws larger (outside of pixel size threshold) entities first

• Defers drawing smaller (inside of pixel size threshold) entities until the end

• Range: 1 200

• Default = 100



displayed


PERFORMANCE

• Framerate Optimization Methods – (Cont’d.)

• Benefits• Reduces waiting for complete redraw

before user can start

• Graphic performance

• Significant performance improvement when model has many faces

• Significant performance improvement when model has extreme number of wireframe entities


PERFORMANCE


• Example

(Framerate = 15; Threshold = 100)

• The first update draws items >100 pixel threshold for 1/15 seconds, and then returns control to the user.

• The remaining updates only runs while the program isn't doing anything else for the user.

• If the user is rotating the model by dragging the mouse, for example, it will draw for up to 1/15 seconds, and then process the next mouse move, which will rotate the model, and start the update cycle again.

• Once the user stops moving the mouse, then further updates will happen to fill in anything that wasn't drawn in the first update. Once everything is drawn, the updates stop.

• Note: This is most effective when running a single maximized viewport. If there are multiple viewports in use in the part, or the part isn't maximized, then it has to give the same 1/N seconds time to each viewport to redraw as it needs it


GRAPHICS CARD

• Driver Types

• Direct3D and OpenGL

• Two technologies which are used to draw graphics on computer screens using hardware features. Certain video-cards support Direct3D/OpenGL of different version, so developers have to deal with different hardware and software. In most cases OpenGL is a good solution because it is standard for multi-platform, and Direct3D is a solution as long as Windows is most widely spread operating system on desktops/laptops.

• OpenGL has wider hardware support, while Direct3D is more widespread.

• OpenGL and Direct3D are both implemented in the display driver

• Direct3D may not support new GPU features


GRAPHICS CARD

• Driver Types

• Hardware OpenGL

• Uses the graphics card OpenGL capabilities

• Important to know the GPU options & their setting

• Access to GPU options vary by OS & cards

• Software OpenGL

• A software graphics driver PC independent

• Does not use graphics card

Windows 7


GRAPHICS CARD

• Driver Types

• Windows GDI

• Used for testing only

• Direct3D

• Uses the graphics card Direct3D capabilities

• Important to know the GPU options & their setting

• Comments

• Most cards have default settings

• Most user do not change GPU settings & maybe should


GRAPHICS CARD

• Display Lists

• Display list is a group of OpenGL commands that have been stored for later execution. Once a display list is created its copied into the display list memory

• Types

• Geometry

• This option sorts the display more efficiently if designs tend to include mostly solids with large numbers of faces.

• Segment

• This option is more efficient at sorting a relatively higher number of entities such as point cloud or wireframe models which have identical attributes (color, level, etc.).

• Segment is preferred over geometry, only use geometry if segment doesn't work right


GRAPHICS CARD

• Anti-Alias

• Anti-Aliasing is the technique of minimizing the distortion artifacts when representing a high-resolution image at a lower resolution based on sampling.

• Sampling Value

• Control sampling level by selecting 2X, 4X or 8X.

• Quality increases with the higher value, but performance decreases.

• Your graphics card must be able to support the selection.

• Full screen

• Applies to everything displayed.

• Lines/Edges

• Applies only to lines and edges.

• Text

• Applies only to text.


GRAPHICS CARD

• Hardware Shadow

• Uses the hardware to render shadows if View>Render>Shadow is used

• Quick HiddenLine

• Uses Hardware OpenGL hidden line capabilities

• May not be acceptable for very complex curved shapes

• OK for mechanical parts


GRAPHICS CARD

• Transparency

• Z-sort

• technique to render translucent polygonal geometry by sorting Z of polygons.

• More accurate but less performance than “peeling”

• Depth Peeling

• Depth peeling is a multipasstechnique to render translucent polygonal geometry without sorting polygons.

• Enter # of levels to peel

• Better performance but less accurate

• Adjusting peeling levels may help


GRAPHICS CARD

• Quick Moves

• Deals with GPU memory methods/algorithms & Graphic card dependent

• XOR

• A swap algorithm that swaps values at distinct, non-overlapping memory location

• XOR draws the geometry on the screen by combining the geometry color with the computed color on the screen in a way that the original color of the screen can be restored by simply repeating the same draw operation. This causes the color of the drawn geometry to be affected by the color over which it is drawn.


GRAPHICS CARD

• Quick Moves -(Cont’d.)

• Overlay

• Draws the geometry in an additional graphics region which is displayed on top of the screen by the graphics card. The original screen contents are restored by simply removing the geometry from the region. This provides true color geometry. This is similar to placing a piece of transparent film over a picture and drawing on the film.


GRAPHICS CARD

• Quick Moves - (Cont’d.)

• Spriting

• Used to describe a technique whereby images are seamlessly scenes.

• Spriting is especially good for integrating 3D objects into 3D scenes in such a way that they can be easily removed in the future.


GRAPHICS CARD

• Quick Moves - (Cont’d.)

• Which to use?

• Spriting is preferred

• The reason these options are here is that some graphics cards don't work well with spriting.

• Overlay is preferred over XOR

• Produces better quality, but not all cards and drivers support it.

• The XOR and Overlay options can't be used together.

• The user must choose one option, and use that for all methods that are enabled but not using spriting.


GRAPHICS CARD

• Quick Moves -

(Cont’d.)

• …Non-Entity Animation

• Setting for non-entity animation like custom cursor, marker, rubberband, etc.


GRAPHICS CARD

• Quick Moves -

(Cont’d.)

• …Wireframe Animation

• Setting for wireframe animation, including detail entities.


GRAPHICS CARD

• Quick Moves -

(Cont’d.)

• …Solid Animation

• Setting for solid/surface animation


GRAPHICS CARD

• Quick Moves -

(Cont’d.)

• …Highlighting

• Setting for highlighting geometry (not necessarily animation)


GRAPHICS CARD

• Test Graphics Card

• Runs a program from TechSoft(HOOPS) that tests the capabilities of the graphics card, and tests whether the graphics card meets the minimum capabilities.

• This program is completely independent of KeyCreator, and doesn't use any KeyCreatorsettings.

– Runs test based on only 2 Driver Type settings:

» If Direct3D is selected as the driver type, then the Direct3D test is run. Otherwise, the OpenGL test is run.


GRAPHICS CARD

• Test Graphics Card - (Cont’d.)

• After the process is complete, KeyCreator will optionally send the graphics test results to Kubotek for analysis.


GRAPHICS CARD

• Test Graphics Card - (Cont’d.)

• Sample test result:Video Memory: 1073741824 bytes (1024 MB)
