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.
SheetNode(std::string const &name)¶
Returns the number of subdivisions per cubic segment to draw in the U direction. See
Returns the number of subdivisions per cubic segment to draw in the V direction. See
Returns the “use vertex color” flag. See
reset_bound(NodePath const &rel_to)¶
Recomputes the bounding volume. This is normally called automatically, but it must occasionally be called explicitly when the surface has changed properties outside of this node’s knowledge.
Specifies the number of subdivisions per cubic segment (that is, per unique knot value) to draw in a fixed uniform tesselation of the surface in the U direction.
Specifies the number of subdivisions per cubic segment (that is, per unique knot value) to draw in a fixed uniform tesselation of the surface in the V direction.
Sets the particular surface represented by the
