Ray-tracing quaternions/hypercomplex fractals
Posted 19 August 2009 - 03:44 PM
I'm asking as I am working on code to ray-trace fractals that will include transparency/diffraction.
So far the only relevant text I've found is the brief outline on Wikipedia regarding Distance Estimation for the "inside" but the algorithm requires too many iterations and is not generic enough for the purposes of rendering general 4D number systems.
I'd appreciate any thoughts on the subject :)

In any case your problem sounds like a Kenton Musgrave sort of thing. I think he either started Pandromeda (they sell Mojoworld) or at least he works there. He's also a pretty famous author and fractal expert. He sent me email personally when I some issue installing the program. We even had a short email exchange. He sounded like a supper nice guy. You might want to look into his work or contact him.

Well that would work if all fractals were 100% convex but if they were then they probably wouldn't be fractals :)

In that case if there's no distance function that works well inside the fractal, it seems like it could be hard to find all the intersections. At least that's what I think the OP is getting at.
