    Is there such a thing as a fractal coordinate system? Are there CAD systems that can generate fractal meshes for example, with cauliflower-floret shaped cells, and turn a 3D scan on a cauliflower into a set of addressable locations like “Floret 3, subfloret 7...”)?

        Semi related my wife just said “cauliflower is perfect because some people want more than others and comes out that way”. Hedghog, Fox, or something more sinister?

        The address scheme you describe works for L-systems.

        Related question, can anything do this in reverse, given a volumetric scan? @EndlessForms

        Topological Data Analysis uses a function (which you can specify) that applies real number values to data (like voxels) to describe topology of your object. It does a bad job keeping track of sub-features, although there is a method "Mapper" that gets close to what you describe

        That's parametric design. Rhino/Grasshopper. AUTOCAD is now 20th C. legacy software!

        In CS terms wouldn't that be equivalent to a method of indexing an ordered tree? Index representing which branch to take at each level of the hierarchy

        One could come up with a spatial tesselation based on wavelets. Multi resolution analyses are like the wavelet analogs of Fourier decompress, done on say a geometric object. I suspect by this point math people who do wavelet based work may already have such coordinate systems..

        (I’m yet unaware of such systems being implemented in CAD software, which historically uses straight Euclidean coordinates in both hardware and software, with most transformations between variations of these.
