I'm trying to map a U value along a NURBS spline.
Imagine a spline that has 4 points:
Now all I need is the uv's to reflect the distance
between these points so that the u value would be:
This could obviously be done by merely mapping $TY to $MAPU.
However, now imagine a nurbs curve that twists and turns -
I need the u value to reflect the length along the curve
to any given point (the arc-length or chord-length).
Hope someone has an answer ...
Thanks for your time,
PS Maya does this automatically :)
