NAME

patch − draws a surface patch

SPECIFICATION

C
patch(geomx, geomy, geomz)
Matrix geomx, geomy, geomz;

FORTRAN
subroutine patch(geomx, geomy, geomz)
real geomx(4,4), geomy(4,4), geomz(4,4)

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

DESCRIPTION

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