NAME

rpatch − draws a rational surface patch

SPECIFICATION

C
rpatch(geomx, geomy, geomz, geomw)
Matrix geomx, geomy, geomz, geomw;

FORTRAN
subroutine rpatch(geomx, geomy, geomz, geomw)
real geomx(4,4), geomy(4,4), geomz(4,4), geomw(4,4)

Pascal
procedure rpatch(var geomx, geomy, geomz,
geomw: Matrix);

DESCRIPTION

rpatch draws a rational surface patch using the current patchbasis, patchprecision, and patchcurves.  The control points geomx , geomy , geomz determine the shape of the patch.  geomw specifies the rational component of the patch to rpatch.
