bgncurve(3G) bgncurve(3G)
NAME
bgncurve, endcurve - delimit a NURBS curve definition
C SPECIFICATION
void bgncurve(void)
void endcurve(void)
PARAMETERS
none
DESCRIPTION
Use bgncurve to mark the beginning of a NURBS (Non-Uniform Rational B-
Spline) curve definition. After you call bgncurve, call nurbscurve to
define the curve. To mark the end of a NURBS curve definition, call
endcurve. The NURBS curve definition must consist of exactly one call to
nurbscurve to define the shape of the curve.
The system renders a NURBS curve as a series of line segments.
NOTE
On Impact and Infinite Reality lmcolor cannot be called between bgncurve
and endcurve
