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
