Volume visualization using adaptive tetrahedral mesh with GPU-accelerated fast cell search

Tracking particles in a complex geometry of such a human body is an issue for the fast calculation of Monte Carlo simulations. An adaptive tetrahedral mesh is a solution for representing the complex geometry. The number of cells affects the calculation speed because of searching cells. However, the cell search is an issue for the calculation speed. Therefore, a GPU-accelerated fast cell search algorithm for the adaptive tetrahedral mesh has been developing. The adaptive tetrahedral mesh generation is described. The GPU-accelerated fast search of cells in the tetrahedral mesh has been developing. The volume visualization software has been also developing for visualizing outcomes of a Monte Carlo radiation simulation.
