Controlling Simulations for Animation Systems

Purposed topic outline

Key Topics• Types of simulations

– Gaseous / Smoke / Small light particles (leaves in the wind)– Liquid– Cloth / Hair

• Methods– Vector Fields– Path Based– Unconnected Particles (ex: Vortex Particles)– System of Particles

• Achieving results– Backward solving:

• Optimization problem• Linear System • Iterative Approach

– Forward Simulation w/ controls:• Animation Controls (wires, particles)

Resources• Thurey. Detail-Preserving Fluid Control SCA06• Wojtan. Keyframe Control of Complex Particle Systems Using the Adjoint

Method SCA06• Shi. Controllable motion synthesis in a gaseous medium VC05• Angelidis. A Controllable, Fast and Stable Basis for Vortex Based Smoke

Simulation SCA06• Treuille. Keyframe Control of Smoke Simulations Siggraph 03• Selle. A Vortex Particle Method for Smoke, Water and Explosions Siggraph 05

• Perhaps others… maybe even an interactive dynamic manipulation of motion capture if no one is presenting it (if there is also time)
