【摘要】 对地质勘探所提供的大规模三维规则网格数据进行可视化处理，针对地质数据特点和地质分析的特殊需要对原有体绘制方法进行简化和改进，大幅度提高重构速度。同时对三维交互等普遍性问题进行了研究，并已取得一些初步成果。更多还原

【Abstract】 In processing large scale data from geological exploration,the 3D Reconstruction procedure is greatly speeded up by the suggested algorithm,which is based on the original volume rendering algorithm (Ray casting) and the features of geological data.Also,the implementation of 3D Interaction is investigated and some initial results are shown,such as the expression and movement of a 3D point on a 2D screen.更多还原
