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.

Features

Common

• Efficient data structures with no use of STL
• Stack and small block allocators
• Built-in math library
• Tunable settings used across the entire library

Collision

• Dynamic tree broadphase
• Static tree "midphase"
• SAT
• GJK
• Spheres, capsules, hulls, triangle meshes
• Optimized pair management

Dynamics

• Contact, friction, restitution
• Mouse, spring, sphere, cone, revolute joint types
• Joint motors, limits
• Constraint graphs
• Simulation islands and sleep management
• Linear time solver
• Stable shape stacking
• One-shot contact manifolds
• Contact clustering, reduction, and persistence
• Contact callbacks: begin, pre-solve, post-solve
• Ray-casting and volume queries

Testbed

• OpenGL with GLFW and GLAD
• UI by imgui
• Mouse picking
• premake build system

Documentation

• Doxygen API documentation
