Optimized volume rendering in object space

Abstract

In this paper, we propose a method of visualization of volumetric data using the developed storage format models voxel-based approach. As a rendering algorithm was chosen splatting, optimized by rejecting invisible voxels. Compared to the standard voxel-based storage method, the amount of information about free voxels was reduced by a group description of free voxels. The bill description format allows the user to enter additional attributes that are required to solve a specific task. The application was implemented using the proposed method, as well as its testing, the results of which prove the fulfillment of the requirements: the size of the files was reduced by 20-25 times, the rendering time was also reduced by 5-6 times.
