I know how to obtain the 4x4 projection matrix of the camera in Blender, but it seems its format is different from the standard camera projection matrices. I would appreciate it if someone explains how I can project a 3D point to 2D (image coordinates) using that projection matrix.

  • Thanks, but I need to know how projection_matrix in the camera object works. In that question, they use world_to_camera_view. – Farhad Dec 04 '15 at 22:51
