1.Considering convolve can be concluded from several inputs to one output, we are allowed to dispose the interested voxel as well as those affecting them, evidently reducing the redundancy.
利用卷积实现多输入到单输出映射特性,仅对兴趣以及对其产生影响的据进行处,极大的降低了据处冗余度;
2.Based on the emission, absorption, diffusion, reflection and scatteration of light by a voxel, it is suitable for generating and rendering realistic images of complex scenes.
