bool is_valid() const
Returns true if the defined surface is valid, false otherwise.
A base class for all things that want to be reference-counted.
This class is an abstraction for evaluating NURBS surfaces.
void omit()
Sets up the surface to omit itself from the output.
void tesselate_uv(int u, int v, bool autoplace, double ratio)
Sets the surface up to tesselate itself uniformly at u x v, or if autoplace is true,...
A reference to an EggNurbsSurface in the egg file, and its parameters as set by the user input file a...
void tesselate_per_isoparam(double pi, bool autoplace, double ratio)
Sets the surface up to tesselate itself to a uniform amount per isoparam.

double count_patches() const
Returns the number of patches the NURBS contains.
void tesselate_specific(const pvector< double > &u_list, const pvector< double > &v_list)
Sets the surface up to tesselate itself at specific isoparams only.
void tesselate_auto(int u, int v, double ratio)
Sets the surface up to tesselate itself by automatically determining the best place to put the indica...
int tesselate()
Applies the appropriate tesselation to the surface, and replaces its node in the tree with an EggGrou...

The result of a NurbsSurfaceEvaluator.
void set_importance(double importance2)
Sets the importance of the surface, as a ratio in proportion to the square of its size.
