How can I group my points, if some of them have 3 or 2 or 1 vertex
I need something like: pointGroup_$NUMBER_VERTICES_IN_POINT
I need something like: pointGroup_$NUMBER_VERTICES_IN_POINT

this is example from The Algorithmic Beauty of Plants.
here & - Correction of segment orientation H due to phototropism T
(& in Houdini - only one of turtle rotations)
how can I implement this correction in Houdini?
T-tropism in houdini - its only gravity
but I need gravity & phototropizm.
thanks!

I have a problem…
In scene example you can see the following…
We have N-polygon. Assign my materials to it I see different results. First – my shader applies to every primitive, another - to all at once. The reason is that s&t parameters in shader taken from different places. One – from global parameters, another – from uvcoords operator. If I use uvcoords –its all good for me. I can apply my shader to surface all at once, not to every primitive.
Problem happens then I assign to my material shaders like stucco, concrete or some another. As I can see that shaders applies to EVERY primitive, not for all in time. In my shader I have some parameters there I can apply uvcoords operator or some UV or st…
In shaders like stucco, concrete I cant find such parameters…
Uvcoords takes st-parameters from UV-texture node in object level. But it doesn’t works with stucco-like shaders…
I cant find the way to rule this problem… What must I do to apply stucco-like shaders to all geometry at once??? Not to every primitive…

I'm looking something like this (in attachment)
Im not familar with houdini specifically in foreach node Can you post some example about this node - there is no examples in help
one more question - if I create curve with numbered point on it, what attributes must I change to rotate each point?
point node have NX, NY - normal directions, and then I type $F - number of frame in place of N*(Add Normal), nothing rotating, or rotating strange but number of frames is changed
I want to change point normal direction depending on frame number… (one frame - one degree) HOW???
may be it have (from 1-to 0) value?? or in radian? or vector?
thanks for replying
