I’ve set aside time the next two weeks to work on BulletSim. As some of you might know, I am the original author of the BulletSim physics engine in OpenSimulator. While other projects have taken up most of my attention, there are some tweeks to BulletSim that are needed.

There are three things that I want to address the next weeks:

• Upgrade the underlying Bullet physics engine to version 2.86;
• Fix the missing collision problem ;
• Raycasting is not done in the physics engine.

The first job is getting re-setting up the build environment. I have to use an old version of Visual Studio and an old version of Linux so the compiled C++ code DLL’s and SO’s will work on older versions of the operating systems.

When I start making source changes, I’ll create an OpenSimulator branch for testing.

Stay tuned.
