OCCT conversion workflows

PSL to XCAF

Convert PSL point clouds to XCAF through surface reconstruction and mesh preparation. Check scan coverage and fitting accuracy before export.

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

Prepare PSL geometry for XCAF

The PSL-to-XCAF route uses the PSL reader, mesh preparation and the XCAF writer. Choose the geometry and representation required by the destination application.

Read the PSL 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.

Build and store an XCAF document

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.

Place the imported geometry in an XCAF document and map the supported names, colors and structure to its labels. Use the native OCCT document storage appropriate to the selected XBF or XML delivery. Mesh data can remain mesh in the document; creating labels does not generate analytic CAD surfaces.

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 document in the intended OCCT application and verify geometry, occurrence placements and mapped attributes. Keep application-specific additions distinct from source properties. XCAF storage is useful for continuing an OCCT workflow, but the recipient must support the chosen document format.

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 PSL to XCAF workflow

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