Hi J-S, Thanks for your interest on this topic. I will try to make a curve drawing interface for my graduation project. So I will inform the mail-list about any updates on curve drawings. Maybe it can be added to a future release of osg.
P.S: Robert thanks for your reply too. I don't want to search 3rd party plugins for tesselation since I don't have much time. I will give a try to osgTeapot example. /emre On Dec 23, 2007 4:00 PM, Jean-Sébastien Guay <[EMAIL PROTECTED]> wrote: > Hello Emre, > > >> Is there any way to render bspline, nurb or any kind of curve in osg ? > > > > There is no parametric support in the core OSG. > > > > You can extend the OSG to support it, and the osgteapot example is an > > example of this.
