Subject: Re: 3D point location problem



no! it is enough to test just one projection, but it must be choosen
carefully, e.g., it is not a good idea to project a polygon which is
perpendicular to xy plane to xy plane, try to estimate the normal n =
(nx, ny, nz) of the polygon, take A = max(nx, ny, nz) and project the
polygon in the A direction (i think this is called the biggest
gradient, but i'm not sure).
