NAME

crv, rcrv − draws a curve

SPECIFICATION

C
crv(geom)
Coord geom[4][3];
rcrv(geom)
Coord geom[4][4];

FORTRAN
subroutine crv(geom)
real geom(3,4)
subroutine rcrv(geom)
real geom(4,4)

Pascal
procedure crv(var geom: Coord);

procedure rcrv(var geom: Coord);

DESCRIPTION

crv and rcrv draw a curve segment using the current curve basis and precision.  rcrv draws a rational curve.  The four control points specified in geom determine the shape of the curve segment.
