If we can't really use Catmull-Clark on triangle mesh, does that mean we have to use another algorithm or do we have to find a way to convert triangle mesh into quad mesh?

can we trivially turn a triangle into a bunch of quads by ex. splitting each triangle into three via the medians?

@justaddwater you can use loop subdivision instead
@jasonx that's basically what catmull-clark is doing here. It works, but you get the noted undesirable properties

When creating a 3D model (e.g. 3D animation context), quad meshes are always preferred and having triangles in a mesh is considered bad meshflow - now I know why!

I still don't quite understand why there's aliasing and poor normal approximation. Could anyone please explain it more?
