RE: [Algorithms] transforming a plane

[Brian M. <bma...@ra...>]

If you are wanting the AABB that encloses the original after transformation
try:

Arvo, James, Transforming Axis-Aligned Bounding Boxes, p. 548-550
http://www.acm.org/tog/GraphicsGems/gems.html

It works by figuring out which of the corners of the bounding box produces
the largest extent along each axis for the new coordinate space.
I'm not sure if this is what you want - but exploiting the extent properties
of a AABB is normally a good way to get fast code with them so hopefully the
concept may help if nothing else.
