Bugfixes: Simplify and correct one derivation of a second derivative of energy function. Clear dynamic variables for static shapes Invalidate contact for a particle when its type switches from dynamic to static Improvements: Allow user to apply force to a particle Allow user to displace a particle Compute kinetic energy Store the mass of each particle, not only its inverse. It can improve performance because the solver needs the masses most of the time for computations Add some code to find shared and non-shared edges. These algorithms don't work for non-manifold meshes Remove some unecessary temporaries decreasing code readability
About
Bounce is a 3D physics engine for games.
To get started with Bounce see readme.txt.
Here is how to control the Testbed. The Testbed is a collection of non-unit tests and examples that helps the author debug features and is not part of the library.
Camera (as in Maya):
- Rotate the scene holding LSHIFT + LMB
- Translate the scene holding LSHIFT + RMB
- Zoom in/out the scene using LSHIFT + Mouse Wheel
Bounce is released under the zlib license.
