Hi everyone,

I've been doing some work on the 3D calculations. You haven't heard from
me for a while, as I had to switch and work on another project.

I did my best to follow the design guidelines that I could find in BG,
and based on that I have a AABBbox, PolygonSoup, Halfspace, LineSegment,
Tetrahedron, TetrahedralDecomposition and similar things + intersection
(test) algorithms up and running in 3D.

Right now, the code is tied to a C++ Computational Fluid Dynamics
framework OpenFOAM - currently only by the Point type and vector
operations (cross/dot product). As soon as I finish the method I'm
working on, I will have time to detach the 3D geometry into a separate
library/repo.

I would really like to work on it until it fits the standards of BG, but
I would probably need input regarding the design from your side. If I
don't get interrupted again by something else, I estimate I will be able
to start porting all I have in a few weeks time. At that point you guys
can see if what I managed to do is worth an effort from your side, or not.

Best regards,
Tomislav
