Universal Solid 3D Format for High Performance Urban Simulation
Jean-François Rotgé, Jérémie Farret · 2007
This article defines principles for a new generation of geometric simulator, able to unify volumic data representation and processing for real time applications in urban simulation. The proposed simulator unifies in particular geometric and graphic pipelines, replacing polygonal surfaces with descriptive polynomials for generalized algebraic surfaces. Such algebraic surfaces are combined with an arithmetical superset of constructive solid geometry system. This approach virtually enables interoperability between CAD/CAM, GIS, AEC, and photogrammetry, through an universal solid 3D data format, designed for high performance computing.
