subdivision surface

can anyone give me tutorial or example how to do subdivision surface eq: doo-sabin in jogl?

Hi

Doo-Sabin isn't a trivial algorithm as far as I know. I have no Java implementation but you can find some tools doing it on Internet. There is a C++ implementation here:

If this is for a homework, we won't do it for you but let us know whether you need some help on any precise aspect.

I have used the Hemesh (Java) library (http://hemesh.wblut.com/) for doing subdivisions together with JOGL.

This is normally a Processing library, but removing the Processing dependencies is not terribly difficult, if you want to use the library in your own code.
