Overview
U3D_Reader supports reading .u3d files (Standard ECMA-363, 1st Edition) in binary format.
U3D_Writer supports writing .u3d files (Standard ECMA_363, 4th Edition, June 2007).

Parameters
Exporter Parameters
Export parameters are controlled by U3D_WriterParameters.
Known Limitations
Importer
- U3D models may contain textures but U3D_Reader doesn't read them yet.
- U3D does not store the unit information. Currently the units are interpreted as meters and the lengths/coordinates are scaled appropriately.
Exporter
- Currently only export of colors is available, but not materials. Some software may display exported models without proper shading and/or color. This depends on whether the software in question relies on materials for coloring and shading, or if it can use diffuse mesh colors.
- The names of the entities in the exported file must be unique. As a result, if there were entities with the same names in the exported model, the sequence number of the entity will be added at the end of the entity name.
