Application of 3D visualization concept layer model for coal-bed methane index system

AbstractIn the information times, comprehending and monitoring the development of science and technology are one of the most important activities. But the fast increasing in technologic information of the network makes people lose their way who finds that it is difficult to comprehend and master the trend of the technologic development. Visualization technology and its open source tools provide a new vision for people to understand the complex structural and unstructured information. In this paper a method of 3D modeling and visualization of coal bed methane index system is proposed. This method integrates basic coal-bed methane index data, borehole discharging data and interpretation section data of geophysical exploration from a view of multi-source data fusion. The 3D spatial data field model is established by using the spatial interpolation technique and drawing technique of the 3D texture hardware assisted volume rendering direct volume is used to realize the volume visualization, and then the spatial distribution characteristics and inner attribute of strata structures are reflected by true 3D model. The method which uses direct volume rendering techniques in 3D modeling of coal bed methane structure can more accurately reflect the coal gas structures and rapidly establish the data field, thus, it possesses good applied prospects. It also stresses the visualization tools used in dynamic monitoring and analyzing the scientific and technologic hot spot of coal bed methane and monitoring the science data of important coal bed methane research based on network database
