I've been trying to figure out a fast way of determining the scissors needed
for shadow volumes. The shadow volumes are directional and are clipped to a ground plane. I've a version running which uses the shadow-caster's oriented bounding box extruded along the light direction and clipped with the ground plane, then each point (16 points) are projected into screen space to determine required scissor region. This in inadequate as it involves too many transformation and min/max checks, so is there any faster method out there (I'm sure it is)?

No bother, I've finally figured out it anyway! :) Thanks anyway!
