I work on an app which is using a projector, which is used to be represent as a camera in Unity.
However as I use a perspective camera (and I want a perspective camera), I’d like to have the same position in Unity and IRL.
To a better understanding, you can see on the scheme in black what a unity camera sees, and in red, what my projector sees and what I want to achieve in Unity.
My problem is that I want my camera Off-axis/off-center but I don’t know how to do it.
I think there’s some things to adjust with the “Camera.projectionMatrix” ( Unity - Scripting API: Camera.projectionMatrix ), but I don’t understand how the script works, and I don’t understand what happens when I change the floats (right, left, bottom, top).
If someone could help me, I’ll appreciate.
