I'm trying to perform some basic image analysis of 3D objects. What I'd like to be able to do is capture in matrix form what a camera would see given distance from object, viewing angle, and resolution of the viewer. Are there any existing functions or toolboxes that could help me achieve this?

You could just do a surface plot of the object, set the camera position parameters of the axes, and then use exportgraphics (which has a Resolution parameter). Then, I guess you could read in the image file back into a Matlab matrix with imread.
