OCCT conversion workflows

PLY to USD / USDZ

Convert PLY to USD / USDZ through a mesh workflow. Prepare geometry, map supported data and validate the result in the receiving application.

Build this conversion into your application with OCCT readers, writers and the commercial components identified below.

Prepare PLY geometry for USD / USDZ

The PLY-to-USD / USDZ route uses the PLY reader, mesh preparation and the USD / USDZ writer. Choose the geometry and representation required by the destination application.

Read polygonal PLY through the Assimp import route. The native OCCT catalog lists PLY writing, while Assimp supplies a PLY reader. Check the imported faces and available vertex properties before selecting an output representation.

Assimp lists PLY among its supported inputs. Select a delivery with that reader enabled.

Prepare a USD scene from the imported geometry

Transfer the imported polygonal geometry into the target mesh workflow. A point-only PLY needs a surface-reconstruction step before a surface-mesh export; changing its extension does not create face connectivity.

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

Check face coverage and the property fields required by the recipient. PLY variants can use different properties, so color and other data need validation against the actual reader and writer mapping.

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.

Conversion integration

Build a PLY to USD / USDZ workflow

Share the source and receiving applications, representative files, required attributes and throughput. We can scope SDK evaluation or an integrated conversion service.
