Hardware it needs, as the project states it
C++ requires a C++ compiler and works on Windows, Linux, Mac OSX, iOS and Android; some optional demos need OpenGL 2 or OpenGL 3. The experimental OpenCL GPU support needs a high-end desktop GPU such as an AMD Radeon 7970 or NVIDIA GTX 680 or better, and does not work on OpenCL CPU devices. The VR s

Overview

What it does: Robotheca's summary

  • Provides real-time collision detection and multi-physics simulation for games, VR, visual effects, robotics and machine learning.
  • PyBullet is the recommended Python interface, installed with pip and aimed at robotics, reinforcement learning and VR.
  • Includes example demos such as an ant and humanoid environments, and a DeepMimic test run.
  • Can run collision detection and rigid body dynamics entirely on the GPU through experimental OpenCL support.
  • Builds with cmake, premake, vcpkg, or Visual Studio, Xcode and Linux makefiles, and can connect to a VR sandbox on Windows.
  • Demos are launched from an example browser and can record movies or screenshots.
