Bezier surface models

Does maybe someone know how to find some free to use models in the form of bezier patches (the cubic preferably) Something like utah teapot but more, TNX

maybe i should switch to nurbs then.. im new in 3d graphics.. searched and i dont find any place with bezier patch models (except utah teapot).. is there better with nurbs surface models.. some repository?friedlinguini wrote:Not offhand, but you could probably generate some from polygonal models (e.g., by converting to PN triangles or subdivision surfaces). I suspect there isn't much call for Bezier models, because if NURBS is more flexible for high-order surfaces.
...Sometimes. NURBS is fine for things like designing mint-condition man-made objects (where smooth, curved, and shiny is important). If you have a lot of geometric detail (nature scenes, scanned 3D objects, etc.), then it's hard to argue that a pixel-sized NURBS patch is more efficient to store than a pixel-sized triangle, and it's those high-detail scenes where storage is a problem.AlbusDumbledore wrote:such curve-patch-models occupy far less space in memory than fat triangle ones -
