Simpler Cvex Example?

[pbowmar]

Hello,

CVEX looks really cool, but um, I don't really understand the example, which I realize shows off lots of things but I really don't get it. Anyone have a simpler example? All I want to do is load a gdp (I know how to do this) that has, say, 4 lines in it. Each line has a prim attribute "seed" which is just its prim number basically.

Then I want to run this VEX code on it, where freq and amp are, let's say, hard-coded.

cvex
simplenoise(vector freq = 1;float amp = 1; int seed; export randpoint = 0;)
{
       randpoint = random(seed);
       P += noise((P+seed)*freq)*amp;
}

and output the newly positioned points.

There is more in my real work but this is jist of it. I don't even see in the CVEX example where the geometry is

Cheers,

Don't everyone rush in at once

OK, so I have to fill an array named the same as the VEX Variable, say "P" and then another to write to, say "Cf".

Any way to act directly on the gdp's points without all this copying/filling arrays?

Cheers,
