Camera projection matrix
I am trying to obtain the camera projection matrix for a camera in 3DS Max. I have no idea as to how i can obtain that information, without manual camera calibration (i.e finding corresponding points between the 3d world coordinates and the 2d rendered image).
Is there a script or a method by means of which given the 3d coordinate of a point, i can exactly find out the points pixel coordinates in the rendered image.
Any help will be greatly appreciated !!
