Based on: https://paulbourke.net/fractals/bioblob/
Done, by brute force, in Nim. The program exports a POV-Ray scene with spheres
or in include file with an array of arrays array[6]{centerX, centerY, centerZ,
radius, parent, generation}, of whitch the skeleton is made.
Now working slowly on speed improvement (R-TreeD?) and ideas to influce the
growth. Wind, gravity, interaction with a container o other growths (forrest(?)

The R-Tree3D works:
spheretests is how many new spheres it tried to place.\
placementTest is the amount of sphere sphere intersection tests. A child sphere
should only intersect with its parent. the Tree makes quite a difference here

Nice composition, wouldn't a higher threshold give the blobs a less artificial,
more organic look? maybe not your goal? but the blur goes in that direction.
Curious about your use of Nim for that. was it pure pleasure, or did bring the
feeling of holding a spoon with chopsticks?
