GLUNEWNURBSRENDERER(3G)GLUNEWNURBSRENDERER(3G)NAME
gluNewNurbsRenderer - create a NURBS object
C SPECIFICATION
GLUnurbs* gluNewNurbsRenderer( void )
DESCRIPTION
gluNewNurbsRenderer creates and returns a pointer to a new NURBS object. This object must be referred to when calling NURBS rendering and
control functions. A return value of 0 means that there is not enough memory to allocate the object.

gluBeginSurface, gluEndSurface - delimit a NURBS surface definition
C SPECIFICATION
void gluBeginSurface( GLUnurbs* nurb )
void gluEndSurface( GLUnurbs* nurb )
PARAMETERS
nurb Specifies the NURBS object (created with gluNewNurbsRenderer).
DESCRIPTION
Use gluBeginSurface to mark the beginning of a NURBS surface definition. After calling gluBeginSurface, make one or more calls to
gluNurbsSurface to define the attributes of the surface. Exactly one of these calls to gluNurbsSurface must have a surface type of
GL_MAP2_VERTEX_3 or GL_MAP2_VERTEX_4. To mark the end of the NURBS surface definition, call gluEndSurface.
Trimming of NURBS surfaces is supported with gluBeginTrim, gluPwlCurve, gluNurbsCurve, and gluEndTrim. See the gluBeginTrim reference page
for details.
GL evaluators are used to render the NURBS surface as a set of polygons. Evaluator state is preserved during rendering with glPushAttrib(-
GL_EVAL_BIT) and glPopAttrib(). See the glPushAttrib reference page for details on exactly what state these calls preserve.
EXAMPLE
The following commands render a textured NURBS surface with normals; the texture coordinates and normals are also described as NURBS sur-
faces:
gluBeginSurface(nobj);
gluNurbsSurface(nobj, ..., GL_MAP2_TEXTURE_COORD_2);
gluNurbsSurface(nobj, ..., GL_MAP2_NORMAL);
gluNurbsSurface(nobj, ..., GL_MAP2_VERTEX_4); gluEndSurface(nobj);

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
