Pc Cluster-based Parallel Processing And Visualization For Massive Mine Spatial Data

The large scale elaboration of three dimensional mine model is the key of Digital Mine. The building of elaborate mine model and furthermore geo-statistical and spatial analysis, such as the accurate calculation of geological reserves, the optimization of the mining, the virtual simulation of mining process and so on, all are related with massive three-dimensional spatial data. Because of the tremendous volume of mine data, it's hard to finish the huge job on ordinary PC machine.The development of PC cluster provides a cheap and powerful parallel calculation environment of digital mine. This paper introduced this solutions and tests on PC cluster-based environment for Digital Mine. Firstly, a solution to build a PC cluster for Digital Mine is provided; Secondly, the parallel processing and 3D visualization for massive three-dimensional spatial data of Digital Mine are studied. Thirdly, two parallel processing systems, one for fast massive voxelization of 3D geological body, and the other for 3D visualization of massive3D spatial data are developed and tested. It shows that the PC cluster is a economical and effective parallel processing and visualizing environment for digital mine.
