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.
__init__(name: str) → None¶
setSurface(surface: NurbsSurfaceEvaluator) → None¶
Sets the particular surface represented by the SheetNode.
getSurface() → NurbsSurfaceEvaluator¶
Returns the surface represented by the SheetNode.
- Return type
setUseVertexColor(flag: bool) → None¶
Sets the “use vertex color” flag. When this is true, the R, G, B, A vertex color is assumed to be stored as the dimensions 0, 1, 2, 3, respectively, of the extended vertex values. Use
NurbsCurveEvaluator.setExtendedVertex()to set these values.
setNumUSubdiv(num_u_subdiv: int) → None¶
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.
getNumUSubdiv() → int¶
Returns the number of subdivisions per cubic segment to draw in the U direction. See
setNumVSubdiv(num_v_subdiv: int) → None¶
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.
getNumVSubdiv() → int¶
Returns the number of subdivisions per cubic segment to draw in the V direction. See
resetBound(rel_to: NodePath) → None¶
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.
