Image data processed by cloud based software and theinitial produced 3D Cloud Model

4

Manual stitching process and the initial 3D Mesh Model

Stitched image that was not automatically stitched on the cloud and then resubmit the scene for reprocessing

5

Creating Reference Points in order to set-up the X,Y,Z directions on 3D Model

In photo lock mode, pick the clear image withthe angle that you want to create the reference points

Autodesk 123D Catch mesh model saved as OBJ File and then imported in SketchUp Pro

Imported geometry remains at 1:1 scale

Sketchup Pro – 3D Model Content of Parliament Square Chapel in Trinity College

• Imported image revealing two sides of the building• Position the Perspective Grips • Position the Axis Origin • Set up Image Scale • Trace Edges with the Line Tool • Checking the 3D with Orbit Tool• Adding the Content Model elements • Final View Adjustments and Export Image• Import a two-dimensional representation of the model in LayOut• In LayOut to create 2D design documentation/construction drawings

Creating the SketchUp ModelUsing

Match Photo

The yellow line represents the horizon line

Red and Green vanishing point grips aligned directly with roof edges and wall lines

Initial view of imported image in SketchUp

This will establish the ground plane of the SketchUp model

Perspective Grips and Axis Origins

Axis origin – the yellow square where the blue and red lines intersect – repositioned to the corner point where the building meets the ground

Orbiting in Photo Match, the photo goes away

With line tool, started tracing edges of photograph creating faces of the model

3D Modelling can be defined as the geometric and graphical object reconstructionof not only buildings but also of the surrounding environment

Why 3D Modelling:

Photo-textured and three-dimensional models enable easy understanding
