Abstract: Analytical expressions are derived for fast calculations of 3D potential integrals. These fast calculation methods remove the singularities from potential integrals and thus achieve very fast convergence with a very small number of sample points. The simulation results show that for a given number of significant digits, the fast calculation method always converges much faster than the singularity cancellation method for the prism domain.
