Title: Grammar-based Encoding of Facades.
Authors: Haegler, Simon1, Wonka, Peter2, Arisona, Stefan Müller1,3, Van Gool, Luc1,4, Müller, Pascal3
Source: Computer Graphics Forum. Jun2010, Vol. 29 Issue 4, p1479-1487. 9p. 2 Color Photographs, 4 Diagrams, 3 Charts, 1 Graph.
Subjects: Real-time rendering (Computer graphics), Interactive computer graphics, Virtual reality, Cities & towns, Prototypes, Graphics processing units
Abstract: In this paper we propose a real-time rendering approach for procedural cities. Our first contribution is a new lightweight grammar representation that compactly encodes facade structures and allows fast per-pixel access. We call this grammar F-shade. Our second contribution is a prototype rendering system that renders an urban model from the compact representation directly on the GPU. Our suggested approach explores an interesting connection from procedural modeling to real-time rendering. Evaluating procedural descriptions at render time uses less memory than the generation of intermediate geometry. This enables us to render large urban models directly from GPU memory.
