# vecmath.rb
# The vecmath library provides Vec2D and Vec3D classes which can be
# use in place of processing PVector, and provide a more rubylike interface.
# Also included in the vecmath library is the ArcBall utility after:-
# Ken Shoemake. Computer Graphics Laboratory. University of Pennsylvania. Philadelphia, PA
# ==== Example Arcball usage see vecmath library in samples
