patch patch
NAME
patch, rpatch - draws a surface patch
SPECIFICATION
C patch(geomx, geomy, geomz)
Matrix geomx, geomy, geomz;
rpatch(geomx, geomy, geomz, geomw)
Matrix geomx, geomy, geomz, geomw;
FORTRAN subroutine patch(geomx, geomy, geomz)
real geomx(4,4), geomy(4,4), geomz(4,4)
subroutine rpatch(geomx, geomy, geomz, geomw)
real geomx(4,4), geomy(4,4), geomz(4,4), geomw(4,4)
Pascal procedure patch(geomx, geomy, geomz: Matrix);
procedure rpatch(geomx, geomy, geomz, geomw: Matrix);
DESCRIPTION
patch and rpatch draw a surface patch using the current
patchbasis, patchprecision, and patchcurves. rpatch draws a
rational surface patch. The control points geomx, geomy,
and geomz determine the shape of the patch. geomw specifies
the rational component of the patch to rpatch.
