Volume rendering of spatial scattered data based on spatial data interpolation algorithms
基于空间数据插值算法的空间散乱数据体绘制实现

Volume rendering technology is one kind of visualization technology, which can truly represent the information within the 3D data sets. And volume rendering of 3D irregular data sets is still a focus in the volume rendering field. This paper introduced the means to transform the spatial scattered data to regular volume data by using spatial data interpolation algorithms, and then implemented the volume rendering of spatial scattered data by using ray casting algorithms. Finally, the volume rendering of the oil distributions in one part of oil storage field was achieved by using the principle introduced in this paper.
