Is there a way to simulate a projector in MATLAB

I am currently looking to simulate a projector in a 3D scene. However from what i have seen in MATLAB so far is that you can simulate a point light source and a point camera. Is there a way to simulate a M by N projector and a M1 by N1 camera system?

projector pixels are, roughly speaking, laser like sources. The only way, i think you an implement rays from a light source is by setting the source at infinite which leads to parallel rays on the scene but thats not exactly what i want.

Similarly for the camera, given a DoF, and intrinsic parameters, i could possibly simulate a M by N camera on my own but would really love if there was a existing function to do it.
