OCCT conversion workflows

OBJ to FBX

Convert OBJ to FBX 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 OBJ geometry for FBX

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

Read Wavefront OBJ polygonal geometry through the OCCT workflow. Check the associated material resources and object grouping where these are used by the source asset. Keep the geometry and its required companion files together.

Prepare mesh geometry for FBX delivery

This is a mesh-to-mesh route. Preserve the available surface triangles, apply the required placements and map only the attributes supported by both the reader and writer. It does not reconstruct a CAD feature history or analytic BRep.

Write the selected mesh geometry with the commercial FBX interface. Prepare the supported scene and placement mapping required by the receiving application. Check appearance and other attributes individually rather than assuming all source properties have an FBX writer mapping.

Validate the converted model

Check object grouping, orientation and units with the receiving application. Normals and material references need explicit validation, particularly when the source uses external resources.

Reopen the FBX in the destination and compare scale, orientation, geometry coverage and placements. Verify the actual version and property mapping needed by that application. Retain the engineering source for information that the scene derivative cannot carry.

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 OBJ to FBX workflow

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