import geometry

General Module Function

The import geometry module will read STL, PLY, OBJ and .G files containing object geometries.  

This module provides the user with the capability to integrate site plans, topography, buildings, and other 3D features into the EVS visualizations.

NOTE: This module intentionally does not have a Z-Scale port since this class of files are so often not in a user's model projected coordinate system. Instead we are providing a Transform Settings group that allows for a much more complex set of transformations including scaling, translations and rotations.

Module Output Ports

• Output [Field] Outputs the CAD layers.
• Output Object [Renderable]: Outputs to the viewer

Properties and Parameters

The Properties window is arranged in the following groups of parameters:

Transform Settings: This allows you to add any number of Translation or Scale transformations in order to place your Wavefront Object in the same coordinate space as the rest of your "Real-World" model. It is very typical that Wavefront Objects are in a rather arbitrary local coordinate system that will have no defined transformation to any standard coordinate projection.

 

Generally you should know if the coordinates are feet of meters and if those are not correct, do that scaling as your first set of transforms.

 

It will be up to you to determine the set of translations that will properly place this object in your model. Hopefully rotations will not be required, but they are possible with the Transform List.
