Research Overview

---

We are currently doing research in the following areas of Computer Graphics:
• Modeling and Visualization of Complex Graphical Environments
  • Terrain and Urban Modeling
  • View-dependent Refinement
  • Stereoscopic Visualization
• Crowd Simulation
  • Path Planning
  • Physcological and Sociological Factors
  • Emergency Crowd Simulation
• Physically-Based Modeling and Animation
  • Deformable Models
  • Human Modeling and Animation
  • Facial Animation

We have been working on developing techniques for the visualization of complex geometric environments, such as terrain height fields and urban models. We developed algorithms for stereoscopic view-dependent visualization of terrain height fields. We proposed a slice-wise representation for buildings, which is a data structure that stores buildings using axis-aligned slices, and exploited this representation to develop an occlusion culling algorithm for urban areas. Slicewise representation brings significant computational and storage gains.

We also investigate various aspects of crowd simulation, such as impact of personality models on crowd behavior, path planning and modeling crowd behavior in emergency situations.
