We propose a mathematical road surface model based upon road axes and properties. In addition, we introduce a process to produce a mesh representing the roads and the terrain so that roads and terrain match. Experiments and compelling results prove the efficiency of our framework.I.3.7 [Computer Graphics]Three Dimensional Graphics and RealismVirtual reality10.2312/udmv.201614149-15
