Image Description, by
My name is Aaron Oman, and attached is an image from a project I'm doing for my computer graphics rendering course
this semester. The topic my partner and I chose was "Real-Time Caustics". Originally we were going to implement
the Wand and StraBer paper on the subject, but we both lacked any experience with pixel shaders and decided to
implement the Daniel Sanchez-Crespo paper at Gamasutra instead. We just implemented the straight OpenGL (no pixel
shaders) version and used the wave-generation algorithm and textures from the paper. The floor texture we're
using, we found on a website that hosts free textures for usage.
Running as-is (which still could use some tweaking, but is definitely serviceable) I get 30 fps on my Radeon 8500
le with an Athlon XP 1700+.
It was a fun project to work on. This was the first time I've ever attempted environment mapping or blending, and
I'm mostly happy with the results.
