The application of computer Three-dimensional visualization technology in railway route selection can improve the efficiency and quality of the design of railway route selection. Three-dimensional railway route modeling is the key of the route Three-dimensional visualization. The Three-dimensional modeling methods are studied deeply in the paper, according to the feature of railway route selection...
Digital representation of terrain surface is an important research area. A number of techniques have been proposed to represent the terrain surface in a realistic manner. They have been broadly categorized as 2D or 3D terrain models. Each of these models has its own merits and demerits. An ideal model will capture the minute details of the terrain, thus requiring more sample points of the terrain,...
The purpose of this research is to demonstrate the possibility of valley landscape reconstruction by VRGIS technology, to design and realize the dynamic observation and changing simulation. The work takes Juntang lake valley as a case. The Delaunay triangulation is constructed by Successive Interpolation Algorithm in order to establish the TIN model. The rainy and snowy scenes are simulated by Particle...
