Modeling, Rendering, and Analysis of Uban Environments

10:00am - 11:15 am
Halligan 111B
Speaker: Peter Wonka, Arizona State University


In this talk I will address three challenges related to urban environments: Modeling, Rendering, and Analysis. Modeling: Creating digital content for virtual worlds remains a significant challenge, especially for urban environments, which are among the largest and most complex. As display capabilities improve and audience expectations grow, procedural modeling techniques are becoming an increasingly important supplement to traditional modeling software. In this talk, I present grammar-based, image-based and interactive methods for the efficient creation of urban environments. Rendering: Urban environments can contain a massive amount of details. I will discuss how visibility computations and compression can help to render massive models in real-time. Analysis: Sensing geo-spatial urban data provides many interesting challenges for data analysis. I will discuss examples of current research projects, such as finding roads in aerial images, classification, and visualization of geo-spatial data.


Peter Wonka joined the computer science faculty of Arizona State University as Assistent Professor in 2004 after two years as a post-doctorate researcher at the Georgia Institute of Technology. He received his Ph.D. in computer science from the Vienna University of Technology in 2001 and a masters degree in urban planning in 2002. His research interests include various topics in computer graphics, especially real-time rendering and procedural modeling. Peter Wonka is a member of the PRISM lab (
