Abstract
A new approach to ray tracing is intro-
duced. The definition of a "ray" is extended into a
cone by including information on the spread angle
and the virtual origin. The advantages of this
approach, which tries to model light propagation
with more fidelity, include a better method of
anti-aliasing, a way of calculating fuzzy shadows
and dull reflections, a method of calculating the
correct level of detail in a procedural model and
texture map, and finally, a procedure for faster
intersection calculation.
