Loading custom objects?

[sidgairo18]

I have an object .stl file which I have build using a 3D CAD software. Can that be imported into the scene?
Or is there any other library where such objects can be imported and rendered.

Thanks.

I have implemented a class named TriangleMesh to load arbitrary .obj files as triangle meshes. So, first convert your .stl file to a .obj format.

However, the rendering is quite slow because we need to loop for every triangle of the mesh, and Python loops are very slow. A bounding volume hierarchy acceleration structure could be implemented, but I think renders will still take a lot of time.

If you want to render arbitrary triangle meshes, Python isn't the language to work with. An implementation in a compiled language like C++ should be needed for speed.
