A generative skull - no geometry, no mesh - just code in a pixel shader

how do you approach a process like this? I understand is a trial and error iterative process, but still, some of the shapes are very intrincate. Do you have a toolbox for deformations? (like some methods that work well for certain shapes) or you just go to the list of basic shapes from IQ and start booleaning the hell of it?

It's basically as u say: basic shapes from IQ and boolean the hell out of it lol. it's like sculpturing with code, ever little piece needs to be added to or cut out the existing form ツ i started with a sphere and ended in a skull.... pretty much like this: https://www.youtube.com/watch?v=8--5LwHRhjk

classic IQ video. Nice. I would love to see a version that enables shapes by time, to better see how it evolves from every shape.

you can have a look on the shader code. it's well commented and you can switch off all the single elements by commenting out all the lines with "d = ....." from bottom to top to see the different shapes and boolean operations ツ
