## Subject: **Re: Piecewise Linear Function of 3d Points**

No this is not quite what I want. I want to attempt to fit a linear

function / set of straight lines to a set of 3d data points that may

have come from a mesh. So it is sort of like trying to find medial axis,

but rather than I want to fit the data with a set of straight lines. I

know I could find the medial axis then simply this, but again without

disclosing exactly what I am trying to attempt, I can't explain why this

is not a suitable solution. So for the moment I am asking given a set of

3d points say modeling an L shape, how can I fit a series of straight

lines through this. I have seen it described in 2d as multi-phase linear

regression, but I can't even find much more information about it and

certainly not for 3d.
