Getting started with Ray tracing.

Getting started with Ray tracing.

Post by Stephen Quattlebau » Thu, 24 Sep 1998 04:00:00



Can anyone point me to a web-site or FAQ, or anything, that gives a good
introduction to ray-tracing for someone with a fairly good base in
geometry and calculus?  I'm thinking of ray-tracing from a structure
representing a BSP tree, and what I've found so far assumes a background
in graphics which I just don't have.
Thanks.

You should consider getting the book _Computer Graphics: Principles and
Practice_ by Foley, van Dam, Feiner, and Hughes. A good intro to ray tracing
can be found on page 776. The book is an excellent computer graphics
reference.

Though Foley et al is a great graphics reference, it's pretty light in its
coverage of ray tracing stuff.  An excellent book on this is "An
Introduction to Ray Tracing," edited by Andrew Glassner.  This is
definitely the book to get if you want to write your own ray tracer; it's
got a great mix of theory as well as good practical design/implementation
advice.

with a heavy emphasis on reference... an easier book to get into which also
has a good description of raytracing is Alan Watt's "3D Computer Graphics".
try finding both and leafing through them to see which style suits you
better. once you do understand graphics theory, the FvDFH book is great for
its thoroughness, but it is not an easy book to learn from...

I agree and would like to reinforce this recc.  The book is a little
old by computing standards, but quite solid.  It developed out of (or
at least in conjunction with) the Introduction to Ray Tracing tutorial
given at SIGGRAPH several years in a row (roughly late 1980's),
organized by Glassner.

Try the newgroup comp.graphics.rendering.raytracing.

And go to http://www.povray.org/ The Persistance of
Vision Raytracer web site.  You can get the POV-ray
source code, compiled binaries, and toutorials.  They
also support a news server.

The book "Practical Raytracing in C" by Craig A. Lindley has been a
valuable resource for me.  There is actually minimal raytracer code in
the first few chapters (although some does not work), and disks with
the original DKBTrace in the edition I bought a few years ago.

See
http://www.education.siggraph.org/materials/hypgraph/raytrace/rtrace0...
for Hypergraph, which has some of the basic material in _An Introduction to
Ray Tracing_ (which I contributed to), plus a lot of new stuff. Some fairly
good slides there, actually. Also see the tutorials section of
http://www.acm.org/tog/BibLook.html.

1. please, help me for getting ray tracing code in 2D case

Hello.

I major in industrial engineering at KAIST in KOREA.

I read "A Theory for Propagation Path-Loss Characteristic in a City-street
Grid" in IEEE Trans. Electromagnetic Compatibilty
 vol 37. No 3, August 1995 pp 333-342 written by S.Y. Tan and H.S. Tan

But I must programming this contents in 2D-case.

Please, help me !!!

I look forward to get this program code of 2D case !!!

please help me !!!

Thank you very much....
