中文摘要： 体矿化模型是基于体视化方法直接构建的矿化模型。但当场景过大、体素过多时，构模速度将大为降低。据此，本课题在体矿化模型的基础上引入计算机并行处理能力，来研究并行计算条件下的体矿化模型的构建及其三维可视化仿真技术。首先，以体矿化模型为基础，研究基于体视化绘制技术的并行构模理论及相关算法；其次，以矿体数据的并行处理为核心，研究并行通信、并行计算及并行绘制等数据处理机制；最后，研究并行体矿化模型的并行体绘制技术框架，并借助微机系统中GPU的并行计算能力实现系统原型，以期解决体矿化模型的三维体绘制与建模速度问题。

英文摘要： The based voxel of orebody model is built directly orebody model based on volume visualization methods. When the drawing orebody scene is too large,or the number of voxel is excessive, orebody modeling of speed will be greatly reduced. Accordingly, this subject introduces in the orebody modeling processing based on the computer's parallel capabilities to study the parallel simulation technology and its 3D visualization of the orebody model based on voxel. First, study on rendering technique based on volume visualization for the parallel orebody modeling theory and algorithms according to orebody model based on volume visualization technique; second, research on the data processing mechanism for parallel communication, parallel computing and parallel rendering, taking parallel processing of the orebody data as the core; third, study on parallel volume rendering framework, and realize parallel rendering system prototype based on GPU parallel computing ability of microcomputer system, in order to solve speed problem of 3D volume visualization and modeling in the orebody model.
