[Bf-committers] GSoC Proposal: NURBS

[Mango Jambo]

Every time I see someone suggesting to get Nurbs working in Blender I think
it is a good thing to see devs getting attention in the way we would shape
things in Blender, using different workflows from what we are use to. It is
a good thing. But I agree with Ton that tools, new or improved, can give us
the same effect with a lower cost.
In other hand, a way to deal with shapes in Blender would be great, but,
IMHO,  not necessarily using Nurbs. I would like to suggest you to check
this link
http://www.fxguide.com/featured/pixars-opensubdiv-v2-a-detailed-look/ . May
be an implementing opensubdiv would give us a greater addition for Blender.
But I'm just an artist. For me it's easy to suggest anything, right? ;)
