Quick experiments on orbit traps to regular 3D Julia sets. I had the idea of trying something like this since one year and a half at least, and I finally found the perfect afternoon to try it. All the images below are the result of that interesting experimental session. Rendering was done based on point clouds (like here
, meaning that you can inspect the fractals in real time). The lighting (that contains both a shadowed directional light and ambient occlusion) is precomputed and stored in each particle.
Because it was a short experiment, I didn't research on how to compute analytic normals for the objects. Instead I estimated the normals by a variation of central differences in the voxel itself.
The first two images used sinus traps, the two following lines traps, the next point traps, and the last a combination of lines and point traps. You can click the small images below to enjoy a higher resolution version.
