OCCT conversion workflows

Parasolid to glTF / GLB

Convert Parasolid X_T and X_B to glTF or GLB. Prepare BRep meshes and map imported names and colors into a visualization scene.

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

Prepare Parasolid geometry for scene delivery

A Parasolid-to-glTF pipeline reads X_T or X_B with the commercial importer, tessellates the translated BRep shapes and writes a glTF or GLB asset. This connects CAD exports to web viewers, engineering portals and graphics applications.

Use the XDE import layer when names and colors must remain attached to model items. Select a document-to-scene mapping that lets the receiving application identify those items after conversion.

Balance geometric detail and loading cost

Choose meshing tolerances for the actual viewing task. Large parts, small features and repeated occurrences may require different preparation decisions. Measure reading, healing, meshing and writing separately so that a slow conversion can be traced to the relevant stage.

Express Mesh provides surface-meshing controls. If the input needs repair, keep the healing resource configuration with the conversion settings to make results reproducible.

Verify item identity and appearance

Reopen the scene and compare scale, placement, names and colors supported by the complete route. A Parasolid export does not necessarily contain the richer scene properties of the destination: texture-based materials or animations need source data or an explicit authoring step.

For glTF output with external resources, distribute the full asset set. For GLB, check the package in the target viewer. Light Web Viewer can connect the resulting scene to application selection and inspection workflows. Keep the BRep source for operations that require exact CAD surfaces.

Conversion integration

Build a Parasolid 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.
