gluBeginCurve
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.
