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.

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.
The Libbulletjme Project is derived from open-source software:
- the Bullet physics simulation kit
- the jMonkeyEngine game engine
- Dokthar's fork of jMonkeyEngine
- Khaled Mamou's V-HACD Library for approximate convex decomposition
- Riccardo Balbo's vhacdBindings
- Stephen Gold's Heart library
- Paul Speed's SimMath library
This project also made use of the following software tools:
- the Antora static website generator
- the Checkstyle tool
- the FindBugs source-code analyzer
- the GNU Compiler Collection and Project Debugger
- the Git revision-control system and GitK commit viewer
- the Firefox and Google Chrome web browsers
- the GitKraken client
- the Gradle build tool
- the IntelliJ IDEA and NetBeans integrated development environments
- the Java compiler, standard doclet, and runtime environment
- jMonkeyEngine and the jME3 Software Development Kit
- the Linux Mint operating system
- the LLVM Compiler Infrastructure
- the Markdown document-conversion tool
- the Meld visual merge tool
- Microsoft Windows and Visual Studio
I am grateful to Riccardo Balbo (aka "riccardo") for bringing V-HACD to my attention.
I am grateful to "dustContributor" for optimizing the cleaner thread.
I am grateful to "elmfrain" for authoring the GearJoint class.
I am grateful to GitHub, Sonatype, AppVeyor, Travis, MacStadium, JFrog, and Imgur for providing free hosting for this project and many other open-source projects.
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.
