Read JT for VRML conversion
A JT-to-VRML workflow combines the JT reader with the VRML writer. Use it when the receiving application needs VRML data from an existing JT model.
JT can contain stored visualization meshes, embedded Parasolid BRep, or both. Select the representation needed for the destination before reading the assembly. The Parasolid interface imports precise geometry only when the JT file contains Parasolid BRep data.
Prepare a VRML visualization derivative
For a mesh route, select a suitable stored level of detail or tessellate the imported Parasolid BRep with the required deflection. For a precise-geometry route, use the embedded BRep; a mesh-only JT file cannot supply the original CAD surfaces.
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 VRML result
Check part placements and repeated instances as well as names, colors and transparency. A stored coarse level of detail cannot regain surface detail merely by changing file format.
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 a production pipeline, keep a representative source file and its expected geometry and attributes with the conversion settings. Discuss conversion integration with the source and destination applications, or compare the supported format interfaces.
