Hi All,

Say I have a mesh, lets say in an L shape. Now I want to fit a piecewise linear function to the vertices or faces (doesn't really matter as both give 3d positions) of that mesh. I know this is quite vague, but I am

Very, very vague. More information is needed. To help you form your intent:
- What is the domain of the function?
- What is the range of the function?
- How do you define the term "fit"?

To make things more concrete:
- What is the application?


Ok, I will try and make myself clearer. Imagine doing a linear regression on some 2d data, now I want to do that to 3d data. This data is the vertices of a 3d mesh. To further complicate this I want to fit x number of lines through the data such that if I just had a straight tube it would simply fit one line through it, but if I was presented with an L shaped tube I would fit two lines through this with 3 control points.
