        public override Vector3D normal(Vector3D intersectionPoint, Vector3D viewPoint)
        {
            Vector3D normal = new Vector3D(ng);

            if (viewPoint.subNew(intersectionPoint).dot(normal) < 0.0)
            {
                normal.neg();
            }

            return(normal);
        }

Example #2

File: Sphere.cs Project: MasterKiller1239/Raytracer

        public override Vector3D normal(Vector3D intersectionPoint, Vector3D viewPoint)
        {
            Vector3D normal = intersectionPoint.subNew(position());

            normal.scale(invRadius());

            if (viewPoint.subNew(intersectionPoint).dot(normal) < 0.0)
            {
                normal.neg();
            }

            return(normal);
