Hello Bob, it answers almost :). On the other side I am more confused than before because I have not yet heard about isometric projection before. I'm basically looking for settings for a CG programs (blender/poser) camera (perspective mode is fine! - 2d orthographic or other cheated modes are not in focus of interest ) that is the same as the "physical" cameras used to make movies are used for. If that is actually possible, that is. http://www.songho.ca/opengl/gl_projectionmatrix.html In OpenGL (and I think e.g. blender) camera perspective is defined by a projection matrix. But I do not know what the correct projection matrix is that movie makers or photographers use when they use their physical cameras. If the perspective in the CG program is different from the perspective of a photo, one cannot reproduce the mesh by sculpting, I think.
