Dr. Isaac Rudomin's recent work focuses on crowd simulation and rendering, as well as tangible interfaces. His work includes simulating and rendering 100,000 to 1 million simple characters in real-time using finite state automata running on the GPU. He also developed animatable facial models for crowds using a small set of representative geometry images and individualized parameters. His tangible interface projects include "Plant Chat" and demonstrations of crowds and fluids.

3. C r o w d S i m u l a t i o n State of the art in realtime large crowd simulation: [Reynolds 2006]:10K characters with Playstation3. [Rudomin et al. 2006]: 100K to 1M simple characters simulated and rendered in GPU . [DeSouza et al. 2007]: megascale agent based simulation for biology simulations. [ Shopf et al. 2008]: 60K detailed characters simulated in newest ATI GPU using hardware tesselation. Agent based crowd simulation has applications in architecture and urbanism, natural disaster mitigation, film and videogames, biological simulation

4. We were the first to specify, simulate and render in real time 100K or more characters using: Finite state automata running in the GPU Agent influence auxiliary images Level of detail and instancing XML scripts automagically converted to GLSL shaders and auxiliary images C r o w d S i m u l a t i o n

6. Animatable facial models for crowds We use a small group (5 to 7) of representative geometry images, three auxiliary images, as well as individualized parameters for modeling and animating each face in a crowd.
