Rigid Bodies

A very simple CPU driven rigid bodies system with an OpenGL renderer. Qt 5 used as the base framework.

The rigid body system implementation is based on the Physically Based Modeling SIGGRAPH 2001 Course notes.

Features

• Control the camera (WASD keys for movement, and mouse left click + mouse movement for orientation).
• Semi-implicit Euler as the numerical solver.
• Collider types implemented:
  • Sphere
  • Cube
• Force fields implemented:
  • Gravity
  • Drag

Known issues

• The resting contact has is not implemented. Instead of applying the resting contact, objects position and rotation get fixed.

Requirements

The software requires the following libraries to be installed:

• GLEW
• Eigen
• QT 5

Build

Clone the repository:

git clone https://github.com/GerardMT/Rigid-Bodies
cd Rigid-Bodies

Compile the code:

cd src
qmake-qt5
make

The builds can be found at build/.

Run

Once build, run the project from the build directory:

cd ../build/release/
./rigid-bodies
