The first version of Bounce has been pushed to the following git repository: https://github.com/irlanrobson/bounce. Bounce is a 3D physics engine for games and interactive applications and hopefully will be a fun project to work on.
I look forward to get a MATLAB license after using the R2015a trial for a week. Scalar and vector functions, gradient fields, and level curves are very easy to be evaluated in my experience. Example:
I gave a simplistic talk last week at university for a couple of math and engineering students about vectors and points. You can download the slides translated to the English language here.
