摘　　要：本文对Splatting算法重采样过程中的的重构函数进行了研究和比较,给出了选择的标准和结论,提出了一种新的基于多重构核的体绘制方法,利用了数据的相关特性,在没有大幅度降低绘制速度的前提下,提高了图像在不同应用场合的整体质量.最后,给出了相应的仿真程序.The paper makes a detailed analyses on the popular reconstruct kernels used in Splatting algorithm. Then we give the criterion to choose a proper reconstruct kernel in the certain condition. At last, we propose a novel approach, which used the mutliresolution method. The choose of the different reconstruction function, depends on the feature of the voxel. According to the results of the emulational program we experiment, the method has been proved useful.
