Hi Vicente,  Love the torus with  noise field scaling down. How did you achieved it? Great work!!

Now I finally got around to play a bit with your definition I have to say: Awesome!!! Looks crazy cool too. Amazing work Vicente.

Still didn't have the time to dig in deeper myself, but this is really awesome!

Did a quick rendertest in Thea Render for Rhino with the wireframe procedural - Some postwork in Lightroom:

So far it seems that the growth is always sooner or later taking over the whole mesh/space, so at the end there is always one big lump.

- It would be interesting to be able to paint areas of the initial mesh in different shades of grey and have the growth controlled by that. 

- Or have the algorithm develop "interest" somehow in certain areas, so the growth is more irregular and diverse.

- Alternatively it could be interesting to have a kind of goal(s) so that the growth is going in a certain direction (-> Light).

Big thumbs-up :-)

Cheers,

Tom

De lo mejor que he visto en mucho tiempo por el foro, maravilloso !

Gracias por compartir, me voy a entretener mucho con el código ~:)

With noise field scaling down over time. For now all the abominations I've grown have begged me to shoot them.

Nick: The color is a gradient that paints yellow the newest vertices and orange the oldest. This was to see which edges are splitting but it doesn't look very good.

Giulio: Thanks, ill try compiling it if I continue playing with this. I haven't really had time to test anything, as soon as it sort of worked I posted it.

Things that are easy to play with is changing the Grow() method. In this animation the rate of growth is related to the position of the edges in a simplex noise field. It looks disgusting but with some care I'm sure some rules can be found that look nice.

Vicente, great work! What the colour generation logic?

This is really cool Vicente!

Regarding speed, I am wondering if you tried putting that code into a compiled component. Especially passing large structs should be relatively faster there. For example, the BoxSphereIntersection method that is fed a Box and a Point3d and several property accesses might be inlined by the compiler.

That is because with the compiler you can compile in Release mode. Maybe David will add that possibility in the future in GH, but for now in order to help debugging (mostly line numbers) we have make up without optimizations in Grasshopper.

After a few more iterations, even after sectioning it you can't tell it was a torus.
