Hello,

I am a student and new for 3D programming.
I do an internship for development an application to compare two 3D surfaces.
For the moment the algorithme is base on the integral of gaussian curvature.

I must work with STL file which contains the position of vertices on triangular mesh.
I would like to get access to each vertice on a triangular mesh  and get the angles of incident edges at a vertex.

How can I do these with Java? Which libraries or methodes?
Which language suggest you to develop this program type?

Thanks for your replies
