NAME
gluBeginCurve, gluEndCurve - delimit a NURBS curve definition
C SPECIFICATION
void gluBeginCurve( GLUnurbs* nurb ) void gluEndCurve( GLUnurbs* nurb )
PARAMETERS
nurb Specifies the NURBS object (created with gluNewNurbsRenderer).
DESCRIPTION
Use gluBeginCurve to mark the beginning of a NURBS curve definition. After calling gluBeginCurve, make one or more calls to gluNurbsCurve to define the attributes of the curve. Exactly one of the calls to gluNurbsCurve must have a curve type of GL_MAP1_VERTEX_3 or GL_MAP1_VERTEX_4. To mark the end of the NURBS curve definition, call gluEndCurve. GL evaluators are used to render the NURBS curve as a series of line segments. 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 curve with normals; texture coordinates and normals are also specified as NURBS curves: gluBeginCurve(nobj); gluNurbsCurve(nobj, ..., GL_MAP1_TEXTURE_COORD_2); gluNurbsCurve(nobj, ..., GL_MAP1_NORMAL); gluNurbsCurve(nobj, ..., GL_MAP1_VERTEX_4); gluEndCurve(nobj);
