Abstract

Splatting is a classical direct volume rendering method based on object order, which volume data exists in layers and each layer of data has similar lines. The amount of calculation data restricts the speed of image rendering. In order to further improve the rendering speed, this paper used a method based on the combination of similarity between adjacent layers and empty voxel jump to speed up the algorithm. It filtered the 3D texture data of the image in the process of reading the data, and then used the footstep table in the 3D texture data after filtering to project in two dimensions. It calculated the gray value of each point by using the similarity between adjacent layers, and classified the data according to the gray value of each point to calculate the empty voxel that had no effect on the imaging, skipped the rendering process and speeded up the algorithm. The experimental results show that the optimized algorithm can solve and improve the spatial correlation and operation efficiency of Splatting algorithm to a certain extent on the basis of ensuring the quality of the drawn image.
