Geological architectural visualization engineering complex geological

Geological engineering complex geological visualization is the use of computer technology, engineering investigation will be converted to image data obtained facilitate interactive visual analysis of the geological structure of the underground space form three-dimensional map and profile graphics,architectural visualization which is based on engineering data visualization and measurement data [4]. The use of visualization technology from large geological survey data to construct the project for the edge of breaking geological stability and deformation and damage other underground chamber play a key role and structure of the rock surface, and show its scope, to cross-cutting relationships and mutual to help engineering geology staff to make the correct interpretation of the original data, then the geological analysis of specific issues for the project to provide decision support. The following diagram (Figure 2) by the surface topography of discrete data interpolation with different colors to express differences in elevation to rolling hills and river erosion cut mountain valley formed the state of visualization.

Figure 2 is hilly and mountainous river erosion cut valleys of the state of the formation of visual

Complex three-dimensional geological modeling and visualization process, from exploration and extraction of geological information in the database the coordinates of the location and physical and mechanical parameters of rock and soil, through different geological fitting and interpolation function get level (surface) and geological entities,house rendering|3d rendering 3D computer graphics display, expression of geological information in the study area of ​​distribution. Geology and geological aspects of rock generated entity, from any angle to achieve the model, to achieve the specified profile, orientation and inclination to generate vertical profiles.
