I maintain the Geometric Tools website (https://www.geometrictools.com) providing freely downloadable source code, much of it motivated by my time spent in the 3D video game industry working on game engines and games. Some source code is based on algorithms I have worked on for contracting, and other portions are based on requests from users themselves. I consider my active field to be Computational Mathematics, because I like mathematics and I like computing. The algorithms and ideas are not new, but I have focused on robustness for computing mathematics when using floating-point arithmetic.
