addattribute in wrangle node

[mawi]

Hi.

Is there a way to create primitive attributes for each point in a curve containing the point position.

int i;
int np = npoints(geoself())-1;

for (i=0; i <= np; i++)
{
v@p0 = point(geoself(),"P",i);
}[/CODE]

Some thing like this in the attribute wrangle primitive mode but with the @p0 concatinated to @p+"i".

Its almost midnight so bare with my messed up brain...

I don't think you can do it purely in VEX. You could if you used the addattribute function but that's not available in CVEX.

Are you trying to add all point positions to all primitives, or just the primitives that actually have that point?

In any case you could probably do it in a ForEach SOP where the attribute access has a channel reference to a parameter on the Wrangle SOP:

v@`chs("attributeName")` = ...;[/CODE]

It's gonna be slow though.

I have x-curves cointaining x-points each.

Now I want primitive attributes (p0,p1,p2,p3...) representing the position of the points in every curve.

I was trying to find a shortcut thru vex, but thinking about it in daylight I might have solved it.
