    two intersecting planes

    what would the results be of rendering two intersecting planes (without sub-dividing them)??

    it that allowed in open gl?

    hey jenny, what's goin on man?

    "what would the results be of rendering two intersecting planes (without sub-dividing them)?? is that allowed in open gl?"

    the intersection of two planes is either nothing (the planes are parallel, but not the same), a plane (the planes are the same), or a line (the planes intersect and are not the same).

    you shouldn't have any problems except for the second case, where the planes are the same. in that case, you're going to get z-fighting problems.

    Try!

    It's allowed, however if depthbuffering is off you might get strange results.
