View Full Version : Aditional clipping planes in world coordinates

11-19-2002, 10:59 AM
How to maintain the coordinates of the six aditional clipping planes in world coordinates, in a way that permits rotations and translations to be multiplied to the modelview matrix without moving the planes in relation to the objects in the scene.
I know that the plane equations are stored in eye coordinates, but I don't want this behaviour.
For instance:
Suppose that I have a car in a scene and specify a clipping plane (might be GL_CLIP_PLANE0) that removes the front part of the car from the exact middle of it. What I want is to navigate around the car while maintaining the front part of car out of the image.

Thanks in advance

The clip plane orientation depends on WHEN you specify it.

Thanks Relic, now it works.
