   Catmull-Clark Algorithm
  hello.who can help me with code of realization of Algorithm Catmull-Clark.It is desirable on  Delphi.I write the program which reconstruct 3D model of face and I need to smooth it.I have decided to use this algorithm but I can't realize it.I poorly present as the model is reconstructed.thanks for the answers and help   
Here and especially here are two resources on Catmull-Clark subdivision.Unless you can find some kind of code sample in Delphi, I think you'll need to implement it from the specification on wikipedia or the original paper it was published in (second link).Hope that helps.   ;  the fact that I already read what is written on wikipedia and could evaluate with the help of the described there algorithm a new situation of points on an example of a cube..point is that that I am weak in OpenGL and yet I do not present as to break ranges and to realize it OpenGL. if at you there is no realization on Delphi me will arrange and on С ++ :)   ;  people HEEEELLLPPP!!!
