Hi Enrico, If I understand your question properly, OpenSG handles this for you through the ProjectionCameraDecorator. The decorator looks for coordinates that defines the corners of the screen. The camera then figures out the correct matrices and asymmetric frustums based on this information and it's beacon. Have a look there since it could save you some time.

I'd like to minimize the perspective distortion felt by the user when he is not standing perfectly in the center of the cave by tracking the position of his head in the real world and then working on the perspective matrix of the application. Is it possible to alter the perspective camera of the viewports to match the position of the head of the user? Was it a single screen I'd just alter the camera position, but being a 3 or 4 wall projection I don't think it's that simple. Anyone did something similar?
