BulletSharp

BulletSharp is a .NET wrapper for the Bullet physics library.

This version uses Platform Invoke. There is also an equivalent version written in C++/CLI: https://github.com/AndresTraks/BulletSharp

libbulletc is a C interface to Bullet. It compiles into a .dll or .so file that exports Bullet functions.

BulletSharpPInvoke is a .NET library that proxies calls from .NET to libbulletc.

The benefit of P/Invoke over C++/CLI is that it runs on all platforms that support P/Invoke into shared user-mode libraries (Windows, Unix, Mac OS). See also Supported platforms.

Build instructions

Prerequisites

• CMake
• CMake-compatible C++ compiler (Visual Studio, GCC, etc.)
• C# compiler (Visual Studio or Mono C# Compiler)

Instructions

1. Fetch Bullet and BulletSharp

• git clone https://github.com/bulletphysics/bullet3
• git clone https://github.com/AndresTraks/BulletSharpPInvoke

2. Generate libbulletc solution files with CMake

• Set the source code directory to BulletSharpPInvoke/libbulletc
• Set the build directory to e.g. BulletSharpPInvoke/libbulletc/build

You can change these options:

• Optional platform for generator - x64, Win32
• BULLET_INCLUDE_DIR - the location of bullet3/src (autodetected)
• USE_DOUBLE_PRECISION - use with the double precision branch
• BULLET2_MULTITHREADING - to enable multithreading, select BULLET2_MULTITHREADING, press Configure and then select available libraries: BULLET2_USE_PPL_MULTITHREADING, BULLET2_USE_OPEN_MP_MULTITHREADING, BULLET2_USE_TBB_MULTITHREADING

3. Build libbulletc

• On Windows, open BulletSharpPInvoke/libbulletc/build/libbulletc.sln and build the solution
• On Unix, open a terminal at BulletSharpPInvoke/libbulletc/build and run "make"

4. Build BulletSharp

• Open BulletSharpPInvoke/BulletSharp/BulletSharpPInvoke.sln and build the solution
