Hi everyone,

I've a bunch of 3D points that make up a collection of surfaces (forming a pile of sand). I want to create a collada file from scratch using these vertices to create my 3D model. I've been going through the collada specifications and have found something called NURBS surface which looks like something that I must use but I don't understand how to use it. Can anyone please suggest me some way by which I can create a collada file using my vertices?
