Who has experience converting OpenCasCade TopoDS_Shape data structures to ASSIMP scene?

[wujie-zxc]

void assimp_export(std::vector<TopoDS_Shape*> &vec, const char *file)
{
Assimp::Exporter exporter;
aiScene t_scene;
//I want to parse the OCC data to fill the scene , then export scene

}

Do you have a documentation about the internals of the data-structure for a TopoDS_Shape? Then we can tr to help you here.

If you have a TopoDS_Shape you can triangulate it and use the triangulation to fill an aiMesh. You can use the STL writer from OpenCasCade as a sample.

With a lot of help from ChatGPT, I have achieved this to some extent. Check out my code here:
