Presentation Transcript

  1. Eugene Paik 2008-2009 TJHSST Systems LabRigid Body Dynamics Simulation

  2. What is rigid body dynamics? In physics, rigid body dynamics is the study of the motion of rigid bodies. (wikipedia) What is my project about? My project focuses on accurately graphically simulating these physical interactions between rigid bodies. Introduction

  3. Applications • Engineering/Architecture • Computer Animation • Video Games • Teaching

  4. “State of the Art” • Havok physics engine • Halo 3 • SSBB • Starcraft II • Fallout 3 • etc.

  5. Development • 2D vs 3D • What language? • Where to start?

  6. Easy Familiar Existing graphics libraries Java

  7. Overview • project.java • Vector.java • Poly.java • Collision Detection • Rotating Bodies • Collision Response

  8. Collision Detection • Separating Axis Theorem • Moving bodies • Rotating bodies

  9. Collision Response • How two objects react to each other when they collide • Physics

  10. Current State

  11. Analysis • Changes to the project: • 3D -> 2D • C++ -> Java • OpenGL → Java Graphics

  12. Conclusion • Bigger project than expected • Research still being done in area • Collision Detection • Physics • Soft-body dynamics/Liquid dynamics
