Member Function Documentation

point3<double> const& pointgrid3Dbilineardraw::operator()	(	uintc	r,
		uintc	k
	)			const [inline]

Patch pointer.

By setting row and col this returns the corner points of that patch.

Definition at line 47 of file pointgrid3Dbilineardraw.h.

References col, pointgrid3D::M, pointgrid3D::N, pg, pointgrid3D::pt, and row.

    assert( r<=1);
    assert( k<=1);
 
    assert(row<pg.M);
    assert(col<pg.N);

    uint index = row + col*pg.N;
    index += k;
    index += r*pg.N;
  
    return pg.pt[index];
  }

void pointgrid3Dbilineardraw::update

(

)

Update the graphics by writing to the graphics container.
