Is there a specific function that can directly associate a face’s tessellation data (A3DTessFaceData) with its topological face data (A3DTopoFaceData)?
I have observed that the tessellation data (A3DTessBase*) comes from A3DRiRepresentationItemData, which is typically obtained from an A3DRiBrepModelData. However, an A3DTopoFaceData is not an A3DRiRepresentationItemData itself; it’s a sub-level structure within it.
Because of this, I tried using A3DRiRepresentationItemComputeTessellation on an A3DTopoFace* but it failed, as the function requires a parameter of type A3DRiRepresentationItem*.
The current workaround I’ve found is to build up the hierarchy from the A3DTopoFaceData all the way to an A3DRiBrepModelData and then call A3DRiRepresentationItemComputeTessellation. However, this process is very time-consuming and, crucially, it does not leverage the existing A3DTessBase* data that I already have from the Brep model’s tessellation.
Is there a more efficient way to achieve this mapping without reconstructing the entire Brep model representation item? Any guidance would be greatly appreciated.
