A Voxel Tree

This is just a teaser of a future post about procedurally generated trees. Here you can see an example of the trees I'm currently able to generate. I would have liked it to be a Christmas tree, but I cannot make evergreens right now.

It is all voxels, which explains why the tree's crown looks a bit like a cloud. That can be improved at lot, this is something I will discuss later.

I am not using L-systems to generate trees. I did try it, but I was not happy with the amount of input that was required. When it comes to trees apparently there are bigger forces at work than just self-similarity and subdivision.

This is using a technique called Space Colonization. Although I modified this method to make it more efficient, you can find the basics here.

    1. algorithmicbotany.org seems to be gone... Weird this was from the University of Calgary.

      "The definitive resource for L-Systems, this University of Calgary site is maintained by Lindenmayers collaborators."

      The main paper can be found here:
