LED体三维显示BCC采样体素化

摘要

In order to reduce the number of voxels and improve the accuracy in the LED 3D display ,BCC sampling methods is used . The"cow"model is taken as an example ,compared with the Cartesian sampling ,BCC sampling with the same number of samples reduces the voxels by 27 .6% .When the number of samples by BCC reduce to 70% of the Cartesian samples ,the voxels can be reduced by 43 .4% .%在L ED立方体三维显示中，为了减少体素量和提高精度，采用BCC栅格采样方法。以“牛”模型进行实验，对比笛卡尔采样， BCC采样在采样点数量相等的前提下体素量减少27.6％；将BCC栅格的采样点数量降低到笛卡尔栅格采样点数量的70％后， BCC采样得到的体素模型实际体素量要比笛卡尔采样得到的体素量减少43.4％。
