Nerox Posted July 22, 2008 Share Posted July 22, 2008 Hi, I would like to rebuild an nurbs surfase after its projected using a 'ray Sop', so I can convert it to polygons and the polygons are nice filled out across the surfase. I can remember I was able to do suge a rebuild in Maya but some how I can't get it done in Houdini. Any suggestions? I've added an scene file.

sibarrick Posted July 22, 2008 Share Posted July 22, 2008 What do you mean by rebuild? It looks like maybe you mean "refine sop" which will add extra isoparms, but then you'll need to re-ray it to make it fix the ray surface. (see attached) But if you just want a Nurbs grid on a tube there are better ways to go about this. I assume what you posted is a cut down example of what you are really doing, in which case you might what to look at creep and paste sops. Maybe if you describe the real situation there are better ways to do this. NurbsRebuild_01_si.hipnc Quote Link to comment Share on other sites More sharing options...

Well, I had a look at the ray_feather tutorial on sidefx.com and I wondered if I could use this ray Sop to rebuild existing geometry like Cad data or other dirty stuff. As far as I can remember Maya is capable of rebuilding a nurbs surface (maybe I'm wrong) so I was wondering if Houdini is able to do this. I one could combine these two things I think it might be a nice workflow to rebuild a car for instance, instead of manualy playing with vertices and faces. The refine sop you've used are more of a fix, I would like to truly rebuild the surface or fill out the faces/vertices equally. Quote Link to comment Share on other sites More sharing options...
sibarrick Posted July 24, 2008 Share Posted July 24, 2008 You can do that but its a bit more involved. When I get time I'll post an example. Its not a one sop solution. Quote Link to comment Share on other sites More sharing options...

I would really appreciate it, but no hurry, it's fantastic you're helping me out any way. Quote Link to comment Share on other sites More sharing options...
