Thread: user clipping plane

  1. #1

    user clipping plane

    hi all:
    the spec. specific the user define clipping plane coefficients in object space
    and must transform to viewing space and perform DOT operation with a viewing space vertex.

    if i want to implement the user define clipping plane feature using
    per-pixel clipping(like texkill in shader)

    does the DOT operation must perform in viewing space?
    or it's OK in object space?

    As long as it behaves identically, implementation details don't matter.
