Lately, I've been working on integrating the Ogre 3D Engine and Bullet Physics Engine together in order to build myself a nice, little engine for future experiments. Here's the progress so far. It is basically a bunch of robots falling from the sky. They pile up and fall off the edge. The physics is simulated by Bullet, and the rendering is done by Ogre.
I have also started using CMake to generate cross-platform build files. It basically allows me to have one build file that will work on all platforms (rather than the mix of SCons, MSVC, and XCode I had before). I've only tested it on Windows (MS Visual C++ Express '08) and Linux (GCC/Makefiles) so far and it seems to be working well. Not sure about OS X yet.
