magneto Posted February 9, 2014 Share Posted February 9, 2014 Hi, If you use a Copy SOP with a NURBS curve as the template, the Copy SOP will copy your geometry exactly on the points of the NURBS curve which are outside the curve (except the first and last). But if you use a Sweep SOP, it copies your geometry at specific positions directly on the curve. I need to calculate the same positions myself. Is there a way to do this? Perhaps in VEX or some kind of expression? Thanks Quote Link to comment Share on other sites More sharing options...
Guest mantragora Posted February 9, 2014 Share Posted February 9, 2014 It's a procedural app, why don't you just sweep and extract those positions from copied geometry? Easier than going into Nurbs math. Quote Link to comment Share on other sites More sharing options...

magneto Posted February 9, 2014 Author Share Posted February 9, 2014 Thanks guys. @mantragora: Yes but I don't need positions but other attributes, so I can't transfer attributes spatially because the curve might be self intersecting, etc. @petz: I tried primuv, but I don't know what U values to use. Just doing PT/(NPT-1) doesn't work, nor seem any U coordinates generated by the Texture SOP. Am I missing something? Quote Link to comment Share on other sites More sharing options...
