Presentation Transcript

  1. Primer to Physics Engines By Matti Larsson and Christian Holmboe, Nya Medier, 5p, VT02

  2. Paper contents • Introduction to physics simulations • Technical overview of algorithms and methods • Overview of existing physics engines • In the summary, we discuss the driving forces behind and the future of physics engines

  3. Introduction • Rigid bodies • Deformable objects • Collision detection • Broad phase • Narrow phase • Constraints

  4. Physics engines

  5. Havok • Cloth is a two-dimensional spring mesh • Fast cloth technique

  6. Vortex • Motion captured character animation • Relative Position, Relative Orientation (RPRO)

  7. Key problems • Stability problems • Scaling problems • Rotation energy • Over-determined constraints • Multi-physics • Hardware concerns

  8. Conclusions and future • Total VR solution packages will emerge • WYSIWYG (What You See Is What You Get) tools • Cheating vs. real physics; examples: • Havok cloth • Vortex character animation, Relative Position, Relative Orientation (RPRO). • Chaotic behaviour • Academic and commercial worlds join forces for standardization and cost sharing
