I has a new problem ;) Here is the situation.
I need to make a cameraview based on a position and normal. The position is pretty easy to implement, but rotation isn't. I have tried making a matrix out of the normal vector and the multiply projection with that, but that changes position of the camera.
In examples found on these forums, people handled the situation by creating a ratation matrix out of quaternion. I' thought I'd try that but I am at loos about how to convert the normal into a quaternion.
