crvn crvn
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.
