The coordinates must -agree with _param7, specified below. -_phead(_param6) -Specifies the order of the NURBS curve. _param6 equals degree + 1, hence -a cubic curve has an order of 4. -_phead(_param7) -Specifies the type of the curve. If this curve is defined within a -_cmnd(BeginCurve)/_cmnd(EndCurve) pair, then -the type can be any of the valid -one-dimensional evaluator types (such as _const(MAP1_VERTEX_3) or -_const(MAP1_COLOR_4)). Between a _cmnd(BeginTrim)/_cmnd(EndTrim) pair, -the only valid types are _gluconst(MAP1_TRIM_2) and _gluconst(MAP1_TRIM_3). -.SH DESCRIPTION -Use _cmnd to describe a NURBS curve. -.P -When _cmnd appears between a _cmnd(BeginCurve)/_cmnd(EndCurve) pair, it is -used to describe a curve to be rendered. -Positional, texture, and color coordinates are associated -by presenting each as a separate _cmnd between a -_cmnd(BeginCurve)/_cmnd(EndCurve) pair. No more than -one call to _cmnd for each of color, position, and texture -data can be made within a single _cmnd(BeginCurve)/_cmnd(EndCurve) -pair. Exactly one call must be made to describe the position of the -curve (a _param7 of _const(MAP1_VERTEX_3) or _const(MAP1_VERTEX_4)). -.P -When _cmnd appears between a _cmnd(BeginTrim)/_cmnd(EndTrim) pair, it is -used to describe a trimming curve on a NURBS surface. If _param7 is -_gluconst(MAP1_TRIM_2), then it describes a curve in two-dimensional (\f2u\fP -and \f2v\fP) -parameter space. If it is _gluconst(MAP1_TRIM_3), then it describes a -curve in two-dimensional homogeneous (\f2u\fP, \f2v\fP, and \f2w\fP) -parameter space. -See the _cmnd(BeginTrim) reference page for more discussion about trimming -curves. -.SH EXAMPLE -The following commands render a textured NURBS curve with normals: -.sp -.Ex -gluBeginCurve(nobj); - gluNurbsCurve(nobj, ..., GL_MAP1_TEXTURE_COORD_2); - gluNurbsCurve(nobj, ..., GL_MAP1_NORMAL); - gluNurbsCurve(nobj, ..., GL_MAP1_VERTEX_4); -gluEndCurve(nobj); -.Ee -.sp -.SH NOTES -To define trim curves which stitch well, use _cmnd(PwlCurve). -.SH SEE ALSO -_cmnd(BeginCurve), _cmnd(BeginTrim), _cmnd(NewNurbsRenderer), _cmnd(PwlCurve) - |
