SheetNode

from panda3d.core import SheetNode
class SheetNode

Bases: PandaNode

This class draws a visible representation of the NURBS surface stored in its NurbsSurfaceEvaluator. It automatically recomputes the surface every frame.

This is not related to NurbsSurface, CubicSurfaceseg or any of the ParametricSurface-derived objects in this module. It is a completely parallel implementation of NURBS surfaces, and will probably eventually replace the whole ParametricSurface class hierarchy.
