According to the image color display, used the RGBA color model, designed the conversion method which changed voxelvalue into its visual properties.
根据图像彩色显示的需要，选用了RGBA颜色模型，设计了样点值和体素的视觉属性值的转换方法。

Method Before volume rendering we transfer each slice of volume into an array indexed by the value of voxels, element in which stores the position of each voxel.
方法在体绘制前，将每个体数据的每个层片编码成以体素值为序的有序数组。

Conclusion Abnormal crossing of multi-fiber within a voxel is one of reasons to cause diffusion anisotropy change. Abnormal crossing of multi-fiber may not affect the FA value.
