bgncur(3G)bgncur(3G)NAME
bgncur, endcur - delimit a NURBS curve definition
FORTRAN 77 SPECIFICATION
subroutine bgncur
subroutine endcur
PARAMETERS
none
DESCRIPTION
Use bgncur to mark the beginning of a NURBS (Non-Uniform Rational B-
Spline) curve definition. After you call bgncur, call nurbsc to define
the curve. To mark the end of a NURBS curve definition, call endcur.
The NURBS curve definition must consist of exactly one call to nurbss 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 lmcolo cannot be called between bgncur and
endcur
