This is an implementation of the <a href="http://www.graphics.cornell.edu/pubs/1997/MT97.pdf"> Fast, Minimum Storage Ray/Triangle Intersection</a> method. This test does not take into account the winding order of the triangle, so a ray will intersect a front-facing triangle as well as a back-facing triangle.

This is an implementation of the <a href="http://www.graphics.cornell.edu/pubs/1997/MT97.pdf"> Fast, Minimum Storage Ray/Triangle Intersection</a> method. This test implements backface culling, that is, it will return <code>false</code> when the triangle is in clockwise winding order assuming a right-handed coordinate system when seen along the ray's direction, even if the ray intersects the triangle. This is in compliance with how OpenGL handles backface culling with default frontface/backface settings.
