Prepare XPDMXML geometry for VRML
The XPDMXML-to-VRML route uses the XPDMXML reader, mesh preparation and the VRML writer. Choose the geometry and representation required by the destination application.
Read the XPDMXML product data through its interface and resolve the geometry required by the selected model items. Keep referenced model resources available; product structure without its geometric content cannot supply an export mesh.
Prepare a VRML visualization derivative
Prepare meshes for the resolved shapes, keeping part occurrences and their placements consistent. Use suitable source meshes directly or tessellate BRep surfaces at the required detail.
Write the selected mesh representation through the OCCT VRML interface for a consumer that expects WRL or VRML. Map the geometry, placements and supported appearance information required by that viewer. Keep precise CAD topology and unsupported attributes in the engineering source.
Validate the converted model
Check geometry completeness and reference resolution before judging the output. Product identifiers, revisions and other management data need an explicit destination mapping or a separate retained record.
Open the output in the receiving VRML application and check scale, orientation and part positions. Verify the actual appearance mapping and any resource references. Compare the tessellation against the viewing task rather than judging fidelity from successful file loading alone.
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.
