Adaptive Cone Tracing is a combination of
cone tracing and adaptive supersampling that provides the following:
- anti-aliasing comparable to stochastic sampling
- anti-aliasing of shadows from point light sources
- area light sources: lines, rectangles, spheres or arbitrary polygons
- anti-aliased and blurry reflections
Details can be found in "Ray Tracing
with Adaptive Supersampling in Object Space" from
Graphics Interface '93 and
Adaptive Supersampling in Object
Space Using Pyramidal Rays" from the March 1998
Computer Graphics Forum.
A short clip from an animation rendered using Adaptive Cone Tracing
is also available as an mpg (830K).
