[vtkusers] Displaying NURBS surfaces in VTK

[David, John]

Since no one else has answered, I'll give it a try...

I consider myself a VTK NooB, and too have an interest in using NURBS with VTK.  After hunting around for quite awhile the positive feedback I came across was a suggestion on using OpenNURBS for the surface/spline part, and VTK for the visualization etc.  Taking a look at OpenNURBS and OpenCAM it appears that the GLU problem was solved some time ago (not -- I have not made an in depth study to make sure).

If you just want to render NURB surfaces, I would suggest taking a look a Blender available at blender.org, Rhino, or similar animation packages.  There are also a number of simulation tools like OpenCASCADE which might work too (again I am not sure of the capabilities).

Other than that I think the whole NURBS question would make for a wonderful addition to the FAQ, but when I went to check the VTK FAQ I got a 404 error...  Maybe I'll have better luck later today.

Best of luck, and when you find a solution, will you tell mee ;-)

Subject: [vtkusers] Displaying NURBS surfaces in VTK
 
Hello everybody,

I need to display a NURBS-surface in my application which uses VTK for
visualization.
There have been a couple of posts on this list regarding NURBS support
in VTK from late 2004 saying it is not possible due to the lack of GLU
integration.

Does anybody know if there have been any changes in VTK that enable
displaying of NURBS surfaces? And if it is still not possible to
directly view such surfaces, is there any opportunity to make a
workaround? What I have right now are the control points of the surface
to be rendered.

Thanks for any help,

Marius
