Read VRML for USD / USDZ output
A VRML-to-USD / USDZ workflow connects the VRML reader to the USD / USDZ writer. Select the model items and output representation needed by the receiving application.
Read WRL or VRML geometry through the OCCT VRML interface. Inspect the mesh content and available placements and appearance before constructing the receiving document. Keep referenced resources accessible during import.
Prepare a USD scene from the imported geometry
Use the imported polygonal geometry for mesh exchange or a mesh-capable CAD container. A scene-format change does not create precise CAD surfaces. Identify any interactive behavior or other source features that fall outside the geometry mapping.
Write USD, USDZ or USDA through the USD component. Map supported names, part placements and appearance into the scene. The component supports meshes, primitives, metadata, materials and animations, but this conversion can preserve only data actually available from the source or explicitly authored by the application.
Check the USD / USDZ result
Compare scale, orientation, geometry coverage and supported appearance. Retain the original scene if its behavior or organization must remain available beyond the geometry exported to the target.
Reopen the scene in the receiving USD application. Compare axis conventions, unit scale, hierarchy, repeated parts and material assignments. Review external resources or packaging for the chosen output variant; the retained CAD source remains the reference for precise modeling.
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.
