doi:10.16182/j.issn1004731x.joss.201707006

Abstract

Abstract: A method of realistic real-time rendering based on road boundary alpha-map was proposed to eliminate the blur and aliasing issues produced by traditional rendering method based on buffer mechanism. In the method, the road was generated by buffer mechanism based on grid model of terrain, and the road's borders were constructed by analyzing the characteristics of road boundary grids. Based on these, three types of road boundary alpha-maps were designed for producing the road borders with realistic visual effects. Experiment shows that the method can improve the rendering realism of the road borders than traditional method. Another advantage of the method is that the number of alpha-map has nothing to do with the terrain size as well as the length and width of road.

Key words: realistic rendering, 3D road modeling, real-time rendering, three dimensional simulation
