I have the need to do some pixel accurate rendering at 7264 X 1184, where each pixel will be mapped to it's appropriate LED counterpart. I have a grid guide set up that I built in Maya and have imported it into Houdini. Each square is equal to 32 pixels. Everything is fine with the orthographic camera but I would like to also create a perspective camera where I want the camera frustum to exactly match the corners of my layout grid. I have eyeballed it for now but was wondering if there is a way to ensure that the match is exact.

Thanks for any help…

I think you can calculate the aperture and focal values using the formulas mentioned here
