Building Virtual Roads from Computer Made Projects

Abstract

Abstract. Driving simulators require extensive road environments, with roads correctly modeled and similar to those found in real world. The modeling of extensive road environments, with the specific characteristics required by driving simulators, may result in a long time consuming process. This paper presents a procedural method to the modeling of large road environments. The proposed method can produce a road network design to populate an empty terrain and produce all the related road environment models. The terrain model can also be edited to produce well-constructed road environments. The road and terrain models are optimized to interactive visualization in real time, applying all the stet-of-art techniques like the level of detail selection. The proposed method allows modeling large road environments, with the realism and quality required to the realization of experimental work in driving simulators.

Procedural generation of topologic road networks for driving simulation

“…After obtaining the definition of the topological road network, the generation of the road path for each roadway takes place. Finally the 3D model of the roads and the terrain are created, using procedural techniques previously described in [4].…”

“…A way to optimize the process of generating the layout of the road from the topological definition is to use tools for automatic generation to facilitate this task, as presented in [3]. For the generation of de 3D models, procedural modeling techniques can be used, as presented in [4].…”
