Single surface representation

Hi there,

im searching for a surface representation for a given point cloud. I know that there are a couple of basic representation such as cubic bezier, hermite surfaces and so on. The problem is that my point cloud is very large. Therefore, a cubic bezier surface would be composed of many cubic bezier patches. Im wondering if there are representations that only use a single “patch” to represent a surface with a large number of control points.


Hi guys

I just found a paper on the subject-matter. For anyone who is interested:



since the paper was a little bit confusing to me. Here is a more detailed description by the same author. It’s her dissertation on “3D Free-form Surface Representation and Its Applications”.
