SoNurbsSurface — NURBS surface shape node

SoGLRenderAction
          Draws the surface based on the current coordinates, material, and so on.

     SoRayPickAction
          Picks the surface based on the current coordinates and transformation.

     SoGetBoundingBoxAction
          Computes  the  bounding  box  that  encloses  all  control  points  of  the  surface  with the current
          transformation applied to them. Sets the center to the average of the control points.

     SoCallbackAction
          If any triangle callbacks are registered with the action, they will be  invoked  for  each  successive
          triangle approximating the surface.

       This  shape  node  represents  a  NURBS  surface  based  on the node's knot vectors and on control points
       constructed from the current coordinates. The current coordinates are used  in  row-major  order  (the  V
       direction corresponds to the rows). The number of coordinates used is determined by the numUControlPoints
       and  numVControlPoints  fields.  The  uKnotVector and vKnotVector fields contain floating point arrays of
       non-decreasing values.

       The order of the surface in the U and V directions is defined as the number of knots minus the number  of
       control points in the particular direction. The largest order allowed for a NURBS surface is 8.

       The  control  points  of  the NURBS surface are transformed by the current cumulative transformation. The
       surface is drawn with the current light model and drawing style. The coordinates,  normals,  and  texture
       coordinates  of  a surface are generated, so you cannot bind explicit normals or texture coordinates to a
       NURBS surface. The first material in the state is applied to the entire surface.

       The surface is trimmed according to the currently defined profile's curves.

       When default texture coordinates are applied to a NURBS surface, the edges  of  the  texture  square  are
       stretched  to  fit  the  surface.  The  axes  of the texture are called S and T; S is horizontal and T is
       vertical. The axes of the NURBS surface are called U and V; U is horizontal and V is  vertical.  You  can
       also define texture coordinates explicitly with the S,T location point, the knot vectors, and the current
       texture coordinates.

       The approximation of the surface by polygons is affected by the current complexity value.
