How can I render a 3D scene for an observer seeing the world through an oblique screen?
Seams so simple: I want to render a 3D world on a tablet that lays on a table (see image)
This would have the following results: 1-The top of a cube located "just below the tablet, parallel to it" needs to be drawn on the tablet as a square (not as a trapezoid). This way, the player (which is at an angle) will see it correctly on the tablet. 2-There will be a vanishing point far down for vertical lines, so the cube's vertical face will be displayed as a trapezoid.
I can't find a discussion about that topic. Maybe nobody knows how to do that?
$$anonymous$$y guess is that you can do this by changing the projection matrix on the camera, though I cannot tell you how:
