Scene Authoring for Virtual Environments

Project Summary

Driving simulation requires high fidelity, correlated scene databases of large geographic regions with properly constructed roads, realistic terrain, natural foliage, and appropriate cultural features. Scene database creation is labor intensive and expensive. The goal of our work is to leverage the work of scene modelers by allowing them to easily reuse database components in the construction of new scenes. This is accomplished through the development of a "building block" approach to scene modeling. Scenes are constructed from prefabricated components (in much the was a model racetrack is built.) By imposing a highly structured format on the boundaries of scene database tiles, sections can be rearranged and combined to create a variety of virtual driving environments.
