Q1) I have an ObjGroup object, (a cube :D). Is there a way of finding the normals for each vertex? Ideally for each face, to account for shared verts at corners.
These are my print outs for a ObjGroup cube.
vertices.size()=8
vertex_indices.size()=36
vertexNormals.size()=0
normal_indices.size()=0
Q2) Should the last two == 0 ?
Q3) Also I've loaded a HDR image into an EnvMapBackground object. Is there a way of looking up a radiance value from a vector? Or do I need to go through Texture<Color>* from within EnvMapBackground?
