Modeling, Rendering, and Analysis of Uban Environments

Abstract

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.
