I looked over his journal the other day and it was quite informative. I'm surprised how things are really that easy. He also got me thinking about Voronoi diagrams, which I completely forgot about. Very cool stuff that I'm working on implementing.
The buddhabrot is interesting. The nebulabrot (lol, who comes up with these names) makes me think of space invaders. I've seen some YouTube videos where they've animated the colours, but if it's possible to slightly animate the shape (slight rotations and what not), it would make for an interesting addition to my video.
The video itself is quite time consuming. I'm rendering it on a dual core 1.8GHz. Some scenes take 2-3 days of processing to film the full zoom on one section at roughly 2048 max iterations (though it varies on what I'm targeting). And if I make a mistake, I smash myself into the wall head first.. To make things worse, I'm producing the videos at 60fps and downsampling the output images from 3840x2160 to 1920x1080. It's really worth it though. I wrote the thing in C++ so there's no fancy assembly going on (see QuickMAN), but I am taking advantage of multithreading. I'm even contemplating adding a network renderer to get my other PCs to join in. Hmm, I should also get the GPU to help out too. Heh, the funny thing is my PC can't even playback the final video. 60fps HD is to much for my crummy PC to handle.
The fractal flame algorithm is a lot worse too since it requires tons of iterations to converge the result. I'd love to do videos with that because it's so fluidic and beautiful, but it would take a month just to do a 1 minute video.
I have a 4d julia on my ATM card
Better to have julia than starfleet's logo on there ;)
