- I wasn't properly scaling the positions for the rigidbody simulation to match the fluid simulation.
- Some of my quaternion calculations were not correct when updating the rotation of the rigid body.
- The coefficients for the interaction forces weren't calculated correctly. I found a detailed formulation for the dampening coefficient in .
- I refactored the rendering code so you can switch rendering techniques on the fly.
- The test program has run-time configurable mass and dimensions for rigid bodies being added.
- Velocity visualization can be turned on/off during run-time.
My plans now are to push my changes into the blender version that Ian already created. Once I have done that I will create some examples and work on writing up my Master's thesis. From then, I will return to working on integrating the library into Bullet. Hopefully, I will get a chance to work on some visualization as well.
