Clockwise checks orientation from this respecting to direction. Revises the orientation of the points A, B, C clockwise, relativly to their direction. If we head from A to B and then to C, we can apply the method of the screwdriver. If this direction points at the same side as the param direction, we obtain true as a result.

"Cross" calculates more then the Method disjoint. In case of crossing, a value lam and the cross point is returned. This value ist between 0 and 1. The line is regarded as a bounded line. For the use of lam watch Plane

This method checks, whether a LineType L intersects the triangle or not. The Line is regarded as a bounded Line with Endpoints A and B. The cross point - if exists - has to lie between A and B.
