Read Blender BLEND for VRML output
A Blender BLEND-to-VRML workflow connects the Blender BLEND reader to the VRML writer. Select the model items and output representation needed by the receiving application.
Read the supported mesh and scene content from the Blender file. Blender authoring data such as procedural operations or editing history must not be treated as exported CAD geometry.
Prepare a VRML visualization derivative
The Assimp integration provides mesh geometry, colors, materials and scene structure for its supported inputs. Pass that data to a separate OCCT or commercial writer. For STEP, STEP XML or DXF output, use the mesh-capable representation; this does not reconstruct BRep surfaces from polygons.
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.
Check the VRML result
Check which objects and their visible geometry are present in the imported result. Keep the original Blender project for authoring data that the exchange route does not retain.
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.
Discuss this conversion with the producing and receiving applications, representative files and required geometry and attributes. Compare the reader/writer catalog when a different representation is needed.
