Space Colonization

Experiments with the implementation of the algorithm in houdini

Great work. Keep it up.

Lets see a few different kinds of trees.

Cool. I also played around with this algorithm a while ago.

Stanford Buddha as a base domain for the points:

It's pretty slow. Sad thing the only way to speed up (build a KD-tree) the point query inside a python SOP is to use inline C++.

Here is a slighty extended example for space colonization mostly based on Entagma's tutorial: https://www.youtube.com/watch?v=XtYkMnM-szY

awesome as always Konstantin.

Could you explain how to shape / art-direct the way it colonizes the space?

Branching behavior etc?

Are space colonization algorithms suitable for that sort of thing?

Cheers

Hi Kilian,

directing those systems is generally possible albeit fiddly. Here is a mixed approach supporting attributes along guide curves. Branch networks and voxel fields are mutually interacting. This one avoids shadows, changes density and varies tangent guidance.

Oh hey, I didn't see your response until now.

Thank you very much! I will look at the file.
