The first version of Particle-Physics Manager was created in 2008 by Ross Meredith, as his project for the third-year undergraduate course Introduction to C++ in the School of Physics and Astronomy at the University of Birmingham. An outline of this first version, which used the Fast Light Toolkit (FLTK) for graphics, is given in his project report (pdf, doc).
Ross continued development of Particle-Physics Manager for a six-week summer project in the Particle-Physics Group, with input from three of the group's researchers: Karl Harrison, Cristina Lazzeroni and Mark Slater. During the summer project, Ross gave a presentation of the game objectives (pdf, ppt), produced a design document (pdf), and wrote a one-page end-of-project report (pdf, doc). The game itself was re-written from scratch, using the Qt graphics library, and implementing the mechanics in an extensible framework.
The next step in the development is to add the physics content.
