1. Rigid Body Dynamics: A Graphical Simulation Eugene Paik 2008-2009

2. Abstract Real-time Simulation Dynamics Calculations  Physics Graphics

3. Applications Physics Modeling Teaching Video Games Sumotori Dreams

4. Approach 2D vs 3D Shapes Efficiency Intuitive Interface

5. Design Java  Existing graphics libraries  Easy object-orientated framework  Familiarity Small steps  Implementing rectangle bodies first

6. Driver Class Check for collisions between each body Apply forces to each body Draw each body

7. Body Class Superclass for every mass Variables to keep track of  Acceleration  Velocity  Position  Mass  Angular acceleration  Angular Velocity  Orientation

8. Vector Class Custom Class for easy manipulation of vectors Necessary when dealing with physics

9. Recent Changes First Version  3D using OpenGL Second Version  2D using Graphics2D Angular properties of bodies creates problems

10. Conclusion Dynamics is a huge field Modern simulations barely touch on the subject
