A voxelization modeling algorithm for point-kernel simulations on 3dsMax files

A voxelization modeling algorithm based on tetrahedral three-dimensional (3D) scan conversion for point-kernel gamma ray calculations is proposed in this paper. The arbitrarily shaped geometries of radiation environment are built by 3dsMax software and the properties of the radiation source and shield material are given directly in the 3DS format file. The voxelization algorithm converts irregular geometry into a compressed voxel model for point-kernel calculation. The algorithm can handle arbitrarily shaped geometries: with or without holes, self-intersecting, manifold or non-manifold. It has fast calculation speed and good shape adaptability. (author)
