[Plib-users] clipping performance question.

[Gouthas, T. <the...@ds...>]

Just an optimization question for frustrum clipping, which would better be
directed to an OpenGL format, but this forum is more convenient at this
point in time.. 

For basic line strips, say of 100's to 1000's of points. Is it worthwhile
going to the trouble of calculating a bounding spehere  for clipping to the
view frustrum, or is line clipping pretty efficient. You would think that an
intelligent implementation would check the end points of a line segment
first and not attempt to draw it if both were out of the clipping rectangle.
Anyone have an idea what OpenGL does?
