Hello J,
Thank you for the reply. I do need the vertices and faces. My
application is to load CAD model and simulate the projection (X-ray image) of
the model according to the materials. So the ability to access individual
vertices are important for my application. Any easy ways to build a program
that able to load different types of model and also can access individual
vertices and faces? Thanks
Xin
