NAME

crvn - draws a series of curves 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 shapes of the curve segments are determined by the control points specified in geom.  If the current basis is a B-spline, Cardinal spline or basis of similar properties the curve segments will be joined end to end and will appear as a single curve.
