NAME

crvn − draws a series of curve segments

SPECIFICATION

C
crvn(n, geom)
long n;
Coord geom[][3];
rcrvn(n, geom)
long n;
Coord geom[][4];

FORTRAN
subroutine crvn(n, geom)
integer*4 n
real geom(3,n)
subroutine rcrvn(n, geom)
integer*4 n
real geom(4,n)

Pascal
procedure crvn(n: longint; var geom: Coord);
procedure rcrvn(n: longint; var geom: Coord);

DESCRIPTION

crvn and rcrvn draw a series of curve segments using the current basis and precision.  rcrvn draws a series of rational curves.  The control points specified in geom determine the shapes of the curve segments.  If the current basis is B-spline, Cardinal spline, or basis with similar properties, the curve segments are joined end to end and appear as a single curve.
