An Improved Ray-casting Algorithm Based on AABB
Volume visualization is one of the advanced technologies in the field of medical image 3D visualization, the efficiency of the volume rendering algorithm directly influences the results of volume visualization. In allusion to the ray-casting volume rendering algorithm,a fast look-up empty voxels algorithm is proposed based on AABB, which shortens the length of ray integral and accelerates the volume rendering. The experiment results verify that the new algorithm is effective in raising rendering speed.
