algorithmic modeling for Rhino

Since I don't have space in my new tiny apartment for a real Christmas tree...

Edge splitting and mesh circle packing using a simplified implementation of this paper: http://www.geometrie.tugraz.at/wallner/packing.pdf

(Kangaroo already does this, probably much better)

...with a genetically optimized candy cane : gingerbread man : ornament ratio hung via a 3D nesting algorithm (garland hung via gradient descent algorithm).

Happy New Yearz!

The tree is also generated procedurally using advanced plant growth and ornamental algorithms, it doesn't come from the first Christmas tree image I found in google.

Looks great Vicente.
Happy holidays!

Despues cambiaste a true el boolean toggle?

Wow, muy bueno!

Pero no pude ejecutarlo, me pone: "error: Parameter is not valid. (line: 0)"

Puse un nuevo estilo de visualización llamado "black", cambié las rutas, y también cambié el nombre del viewport a "tree" y nada.

De todos modos... Feliz año nuevo! :)

Btw, there are some multithreaded loops which are pretty useless since the bottleneck is the edge splitting.

File: CPTree.gh

For the script to work:

- Create a custom display mode named "black" (with black background, no grid/axis and nice lighting).

- There's a string with the location of an image file, rename it so it points to an image in your computer.
