Is there a way to find the arc len of a curve in vex?

Specifically, each points position along the arclen?


thanks!

This thread(http://forums.odforce.net/topic/10092-curve-u-parameter-to-attribute/ [forums.odforce.net]) has some suggestions; the consensus of that discussion seemed to be the Arc Length Spline mode of UV Texture SOP is the way to go. The @uv.x would be the arclen at that point.

There is also a suggestion in there to re-sample then do it in VOPs.

Hope that helps!
