OCCT conversion workflows

USD / USDZ to glTF / GLB

Convert USD, USDZ or USDA to glTF or GLB. Prepare supported scene geometry and define hierarchy, material and metadata mapping for web delivery.

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

Prepare USD scene content for glTF delivery

The USD reader imports USD, USDZ and USDA, including meshes, primitives, names, hierarchy, colors, metadata, materials and animations. A USD-to-glTF integration selects the scene data to retain and writes it through the glTF interface.

The source component’s read coverage and the destination writer’s coverage must be considered together. Importing a property successfully does not mean that every target scene format or writer can express it in the same form.

Convert scene geometry and select attributes

Use the supported mesh representation for scene output and prepare any imported primitive representation that needs conversion for the target. Define which scene items, placements and names form the delivered asset.

Material models, metadata and animation need explicit mapping decisions. Some applications need a static visual derivative; others require motion or application metadata. State the requirement and verify writer support instead of silently treating the same pipeline as suitable for both.

Reopen in the target viewer

Check orientation, scale, object visibility, hierarchy and appearance in the intended glTF or GLB consumer. Verify that the package includes the resources needed by the selected delivery form. Compare representative scenes with multiple materials and nested structures.

For an engineering portal, Light Web Viewer can connect scene interaction to the surrounding application. Keep the source USD scene for properties or editing workflows that the glTF derivative does not retain. Custom integration services can define these scene and enterprise-data relationships.

Conversion integration

Build a USD / USDZ to glTF / GLB workflow

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