Thanks Robert. Alright, here is the deal. I'm trying to draw a 3D triangular mesh with osg. For some mesh, the calculated normal points to the inside. So, I want to draw both the front and back faces, which have opposite normals. Then you can render the mesh visible. Is there an example of this? Thanks!
