Method inOrthoSphereExact

Slow exact 3D in-ortho-sphere test. Returns a positive value if the weighted point pe lies inside the ortho-sphere defined by the weighted points pa, pb, pc, and pd; a negative value if it lies outside; and zero if the five points lie on the same ortho-sphere. The points pa, pb, pc, and pd must be o
