Buddhabrot Grand Tour

This is a detailed and technical tour of the Buddhabrot.  The zooms and rotations are slow to give the viewer a chance to see the details and relationships between the different parts of the fractal which become noticeable as it's rotated.  

I spent a lot of time writing my own Buddhabrot renderer from scratch.  The frequently cited random sampling and Metropolis-Hastings methods didn't seem to resolve the level of detail that I was after, so I worked out some original methods to give greater detail while having enough performance to produce an animation with some zooming and rotation.

There is very little post production and the images in the sequences are as the renderer output them.  I wanted this video to showcase the technical side of rendering this challenging fractal moreso than any artistic editing that could have done.

I really enjoy it.
I "can't judge" technically, because i'am not a "master"  in this kind of computation, but really nice work. Some part make me think about "universe", nebula clouds.
Thanx

cool trip into a mandelbrot mobilee cheesy how come the 3dish look !?


Thanks.  Each iteration of Z=Z^2+C can be though of as a point with 4 dimensions - C-real, C-imaginary, Z-real, and Z-imaginary.  If you render an image with the Z-real, Z-imaginary values you get a Buddhabrot, if you render it with C-real, C-imaginary values you get the traditional Mandelbrot.  Rotating just involves using standard math to rotate between any two of the axis.  For example at about 0:25 it begins rotating from the view Zr, Zi to Cr, Zi
