Are meshes faster than nurbs?

I''m just guessing, but since nurbs are so smooth i assume they are a lot slower than meshes, even if it has enough vertex to simulate a smooth surface?

Can''t say I know *for certain* but I''d imagine NURBs to be slow-as-hell compared to a mesh-based model.

Well, the NURBS are used in modeling programs because they can change resolution since they arent escentially an object but a ecuation.

With NURBS you can create an object that in memory an viewport is really fast, but in render they are Slow-as-hell (but with a really better resolution).

NURBS can be as faster as MESH, bacause before render
nurbs are transformed into a mesh with the desired resolution.

If you generate a mesh from NURBS with 10 polygons it will
be the same as having a simple mesh with 10 polygons, so
the speed on rendering is the same.

In addition to kamikaze15''s post, you would probably use NURBS for graphics card compatibility in games. Then you could still support an ATI Rage 128 and also provide the best graphics for the Geforce FX, or even newer graphics cards. I assume you could do the same with lighting and textures, as is becoming more important in games nowadays (Doom III).
