Surface recostruction from scattered points cloud Part1

Builds a triangulated surface given a 3D points cloud. They do not need to be in the z=f(x,y) form

Description

This is a simple Surface recostruction code based on crust algorithm. Given a 3D points cloud returns a tight triangulation.  
   
This version lacks surface post treatments so the output could be not regular. Anyway it gives an idea of how the surface looks like. So for graphical purposes this should be good.  
 
Remember the crust algorithom needs a cloud representing a volume so open surface may give inaccurate results. For example : a plane can not be triangulated, a semi-sphere yes.  
For open surface you can see Part2 of my submission.  
 
The more points are given the best the surface will be fitted, of course in this case you would have to wait more and in the worst case a memory help error may occurs. The best results are obtained with more points in high curvature feature.  
 
 
If any problems occurs in execution, or if you found a bug, have a suggestion or question just contact me at:

Espacially on models which the algorithm fails. Thank you.

Hi 
Excellent contribution. 
with some small modifications, I could also use it for visualization of my 3D colored surface data. 
Thank you very much, 
 
regards,
