Hi to everyone, I'm try to extract a portion of a 3D plane in order to simulate a video camera view.
For example, I have generate a random x,y and z plane (like a ground). I suppose to have a moving camera that face down respect to the plane at a certain height. How i can project the camera view in order to extract only a portion of plane that the camera see, supposing to have a certain focal length? My plane is define with 3 2x2 matrices, I attach an example
