Hello everyone,

I am trying to move points along curves in world units as supposed to, say @curveu or @primuv which are 0-1 values as far as I know. So, I cannot use a carve to exctract a point along a curve for example. The main reason for this is that I need a way to be able to move points on multiple curves, but by the exact same amount irrespective of the actual curves different lengths. So, is there a good, fast way to do this?

Thanks,

Dag

you can use primuvconvert() [www.sidefx.com] VEX function to convert real distance value to parametric 0-1 coordinate

That sounds interesting tamte! I'll give that a try. And, btw, I would use something like the primuv() function to actually move the points? Or something else/better?

Thanks!
Dag

You can use primuv to get 3d positions in world space.

Thanks for your reply animatrix, I'll look into this soon and resolve my problem
Cheers,
