The Libbulletjme Project adds JNI "glue code" to portions of Bullet Physics and Khaled Mamou's V-HACD Library, enabling 3-D physics simulation from Java applications.

Complete source code (in C++ and Java) is provided under a mixed open-source license.

The project supports the 3 major desktop operating systems: Windows, Linux, and macOS. Both the x86 and x86-64 architectures are supported for each operating system. It also supports Linux on ARM (armel, armhf, and aarch64) and macOS on ARM and provides native libraries for the 4 supported Android ABIs (armeabi-v7a, arm64-v8a, x86, and x86_64), making a total of 14 platforms.

For each desktop platform, 4 native libraries are distributed:

  • a release build using single-precision arithmetic (the default library)
  • a release build using double-precision arithmetic
  • a debug build using single-precision arithmetic
  • a debug build using double-precision arithmetic

In addition, multithreaded native libraries are provided for x86_64 architectures running Windows or Linux.

Libbulletjme is used in the DynamX Physics Mod for Minecraft.

Libbulletjme's native libraries are used in Minie, which integrates Libbulletjme into the jMonkeyEngine game engine. For applications that don't use jMonkeyEngine, standalone Maven artifacts are provided.

History

The evolution of this project is chronicled in its release log.

The C++ glue code for Bullet was originally copied from jme3-bullet-native, a library of jMonkeyEngine. The soft-body portion was added in 2018, and is based on the work of Jules (aka "dokthar").

The Java code is based partly jMonkeyEngine, partly on Riccardo's V-hacd-java-bindings, and partly on Minie. Minie is, in turn, based on jme3-bullet, another jMonkeyEngine library.

I am grateful to ndebruyn for helping me test the Android native libraries.

I am grateful to Pavly Gerges for helping me test the armhf native library.

I am grateful to Yanis Boudiaf and "qwq" for many helpful suggestions.

I'm also grateful to my dear Holly, for keeping me sane.
