Hello all, let me introduce myself. My name is Martin,
and i'm a student in a university in Indonesia. Right now,
i'm studying Ray Tracing as my Final Project, but i can't
find a good resource on the net. Actually, it's not the
Ray Tracing itself that bother me (because i have already
taken that lecture subject). It's the Cone Tracing, because
my final project will heavily based on this optimizing-
techniques of Ray Tracing. And it's very little resources
on the net of the Cone Tracing. All that I know is that
the Cone Tracing is an optimization of Ray Tracing that
forms a cone to shoot rays instead of shoot ray to all
direction (which waste optimization). Please for you who
can give me a little hints about the cone tracing and the
formula, or maybe give one or two url of good references
of Cone Tracing on the Net. Thank you very much. I'll wait
for your reply, guys.

God bless you all,
Martin
