Prepare PTX geometry for USD / USDZ
The PTX-to-USD / USDZ route uses the PTX reader, mesh preparation and the USD / USDZ writer. Choose the geometry and representation required by the destination application.
Read the PTX scan data through the point-cloud interface. Select the scan region needed by the destination, establish units and alignment, and inspect sampling density and missing areas before constructing a surface.
Prepare a USD scene from the imported geometry
A surface-mesh destination requires face connectivity, not just point positions. Reconstruct the required surface from the imported points, then tessellate it or prepare the resulting polygonal mesh. Surface from Scattered Points provides a surface-fitting workflow to evaluate for this preparation step.
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.
Validate the converted model
Compare the reconstructed surface against the scan, including gaps, noise and sparse regions. Specify fitting tolerances and how boundaries or missing areas are handled. The mesh is a derived surface whose accuracy depends on the source samples and reconstruction settings.
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.
For repeated jobs, retain the source, preparation settings and representative output checks. Discuss this conversion with the input files, destination application and required geometry and attributes.
