In Case of Bomb Threat

• Go across the street towards the Stadium
• Like my gym teacher used to do youll all do
  wind sprints until the guilty parties confess
• Meet in that parking lot for continued instruction

More Questions from Recent Papers

• Predicting the Drape of Woven Cloth Using
  Interacting Particles
• Could it produce quantitative results?
• Could you simulate individual strands of cloth?
• How much better are simulated cloth models over
  hacked ones?
• Introducing noise?
• How is texture mapping applied?

• Faster simulation methods?
• Modeling thickness?
• Flattened folds?
• Can we change parameters to represent wool,
  cotton, polyester,

More Questions from Recent Papers

• Timewarp Rigid Body Simulation
• When does the system perform best/worst?
• How can you check if two bodies passed entirely
  through one another?
• Scaling this to real parallel system
• Practical applications
• Application to soft bodies (collisions)
• Where does rendering of frames fit in?

Rigid Body Simulation Continues

• First clarify assignment 3
• Part A of the assignment is particles only
• No angular terms (MOI, w, a, etc.)
• We replicate angular term simulation by building
  multi-particle objects (soft bodies)
• Drawback to this technique is that we are not
  going to model effects of particles striking soft
  body

Rigid Body Simulation Continues

• Part B of the assignment could be full rigid body
  simulation
• Add rigid bodies (defined by a set of points, not
  individually simulated particles) to your scene
• Get angular terms right
