Abstract :
The first step in FEM-based deformation is voxelization, which means objects showed in original mesh will be desecrated into mass of small units (voxels), and then the characteristic matrix can be fetched with the coordinate, shape, and attributes of voxels. This paper focuses on the reciprocity between specifying voxel physical parameter and simulating the deformation. A table list out provides physical properties used to manufacture voxels. The experiments and results point out the significance of setting up material traits for reliable deformation simulations. Specifying the range of elastic strain, the plastic strain, and the maximum of failure force of a model by manufacturing its voxels helps to obtain more ideal simulation results.
