3D Strange Attractor visualized in 3Delight with ray-marching shader

I started this in 2008 and hope to get back to it soon. Basically, I have computed a voxel approximation of a three dimensional chaotic dynamical system, and adapted a ray marching Renderman cloud shader used in the movie Contact to visualize the attractor via 3Delight. This is just work in progress, an attempt to capture the true volumetric, delicate and fascinating form of these generative artifacts.

It’s so hard to get enough resolution on rasterized 3D volumes. I’ve tried on multiple occasions and never been happy with the result, especially when there are sharp details as with these strange attractor maps. I love your use of color, nonetheless.

Thanks Mark! It’s so true. Trilinear filtering got me some more mileage here but it was a struggle against artifacts for sure.
