Read USD / USDZ for VRML output
A USD / USDZ-to-VRML workflow connects the USD / USDZ reader to the VRML writer. Select the model items and output representation needed by the receiving application.
Read USD, USDZ or USDA with the USD component. It supports meshes, primitives, names, hierarchy, colors, metadata, materials and animations. Select the scene nodes and the scene state required for the receiving workflow.
Prepare a VRML visualization derivative
Prepare the imported meshes and any supported primitives for the target representation. For a static output, select or evaluate the required animation state in the application and apply the corresponding placements. Source animation support does not make a static CAD or mesh format animated.
Write the selected mesh representation through the OCCT VRML interface for a consumer that expects WRL or VRML. Map the geometry, placements and supported appearance information required by that viewer. Keep precise CAD topology and unsupported attributes in the engineering source.
Check the VRML result
Validate unit scale, orientation, nested transforms and geometry coverage. USD materials, animation and metadata need individual mapping checks; only properties supported by the destination can travel with the converted model.
Open the output in the receiving VRML application and check scale, orientation and part positions. Verify the actual appearance mapping and any resource references. Compare the tessellation against the viewing task rather than judging fidelity from successful file loading alone.
Discuss this conversion with the producing and receiving applications, representative files and required geometry and attributes. Compare the reader/writer catalog when a different representation is needed.
