I'm presently working on an honors undergraduate thesis in ray-tracing.
The algorithm I'm developing should save a significant amount of time
for scenes of the following types:
1. many objects
2. ones with large objects in the foreground taking up a significant
amount of screen space.
Basically, I'm modifying DBW_Render to use a 3-dimensionally, spatially
sorted, doubly linked list in order to reduce the number of ray-object
intersections, eliminate sorts, and in general reduce rendering time.
I would be very interested in obtaining numerous 3-d object description
files to benchmark on the ray-tracer. These would include things like
3-d molecules, houses, trees, etc. and any procedural algorithms as well
(large sphere of smaller objects, Sierpinski gadgets, etc. I will be
sure to acknowledge any contributors of objects (even if I don't use
any that you've contributed) in the final paper. Along with the description
please provide an explanation of the format of the object.
Just to let everyone know results obtained so far, I've reduced the
rendering time of a >400 object scene by 2-3 times (rendering time for
standard DBW estimated on a portion of the screen rendered).
Please e-mail all 3-d files, with explanations to : prem@geomag.gly.fsu.edu
Thanks much in advance.
