Description
The Mandelbulb was an attempt to recreate the Mandelbrot Set in 3D. It was largely considered a failure at first. However, as I explore it further, and render it in higher detail, I am finding that the fractal has some quite interesting detail. The aim of this video is to show you what is actually there. So I've called this a "technical render", its not an attempt to be artistic. Please give me your thoughts in the comments. There two parts to this render:
0:00 Wide View of the Needle
1:42 Close-up View of the Needle
3D fractals are much harder to render than 2D fractals. There are a number of trade-offs to make as we can't simply assign colours to iteration counts. Most renderers for the Mandelbulb fractal rely on graphics card running at 32-bit precision. However this severely limits how close we can get.
This is an attempt to render the Mandelbulb at full 64-bit double precision, which was done on a CPU. It is early days for my little software renderer, so there are a few problems, but it does expose some detail. It would not be possible to render the 2nd part of this video at 32-bit. It is significantly more zoomed in.
The close-up view actually only takes you to the main mini-bulb shown in the fist video. It is significantly more zoomed, and you are seeing much less of the needle.
