UV point attribute to a ramp.

[Symbolic]

Hi,

This may sound strange. But I have to do the following.

* I have a curve with UV attribute. (0-1)

* I scatter n points on the curve (ex: 4 points)

* I know the UV attribute for each point:

P1 = 0.1

P2 = 0.4

P3 = 0.6

P4 = 0.9

* Somewhere else I have ramp parameter.

I need to make something like that:

"I have 4 points, create 4 points on the ramp as well and set their position to the corresponding U locations"

So I get a ramp with 4 points... set eaxctly at 0.1, 0.4, 0.6, 0.9

Please do not get mad if this sounds creazy!

(And I do not know what is going on, but my firefox is not performing splle check anymore! )

just some bricks that might help ....

from the help:

__init__(self, basis, keys, values)
>>> lin = hou.rampBasis.Linear
>>> hou.Ramp( (lin, lin), (0, 1), (0, 1) )

basis is the interpolation, keys are the keys and values the values ...

for p in node.geometry().points():
 p.floatListAttribValue("uv")

this returns the UV values of your points.

the problem here might be that scattering along a curve doesn't necessarily create an ordered sequence of points.

Thanks rdg!

I will give it a try... Although my python skills are still very poor. So If I want to have a button around my ramp... something like "Update ramp"...

Then I will build my script inside this button? Right? So the script can dive into the sub networks... find the points... get their 0-1 position and transfer this into the ramp?
