Question by Matthew_Ostil · Feb 14, 2020 at 07:54 PM · raycasting projection-matrix

ScreenToWorld raycasting with panini projection

Hi everyone,

We're doing a large FOV interactive (120 degrees) and were hoping to use a single camera for the view. To avoid as much distortion as possible, we applied a panini projection in the post processing volume which looks great.

However, in this interactive, players will be controller screen space aimers which translates into a point in the world via a raycast from the camera. Of course, because of the warping of the panini projection, the position of the UI aimer doesn't translate into the real world position of the raycast and thus, the shot doesn't align.

Any help is appreciated, thanks!
