"It looks like that your srfs are planar... So i think you can use plane to plane mathematical intersections.
Im on the phone, but i think you need to graft input a and for input b you need cull list plane by index, using as index a series number…"
"I remember using a script from here in the forum that works...
Also you can use the dot product between normal vector from the surface and a reference point to know if you need negative or positive value to the offset."
"You really need to di sime tutorials first....
Anyway... I think that the extend curve component works with negative values, so if you enter negative radius value youll shrink the line.
Pd: for negatives values multiply -1"
Hey Manuel, I tried to use your L-system fractals definition to generate branches. I was able to make it work, but now I want the branching to start at certain UVs of the surface, but it doesnt seem to work. Would you please look over my definition and see whats not working. Also the definition I have set up right now is producing duplicates of the same line.
