NAME

gluBeginCurve, gluEndCurve - delimit a NURBS curve definition

 

C SPECIFICATION

void gluBeginCurve( GLUnurbs* nurb ) 




void gluEndCurve(
GLUnurbs* nurb )






delim $$

 

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);
