Paper Abstract

In order to combine rugged terrain and abuttals efficiently and accurately in current GIS, an improved method is presented which realized abuttals rendering on rugged terrain by the way of combining buffer object and ZP+ algorithm which comes from Z-pass. We create the shadow volume via extruding abuttal data, then play real-time rendering ,determine the width of shadow volume dynamically using screen-space error metric, as a result, the volume could fit the scene closely. For improving the render rate we store the volume vertex arrays using buffer object. Experiments indicate that the method advances the program performance, combines abuttals and terrain closely and meets the demand of display.
