Accelerated path generation and visualization for numerical integration of feynman path integrals for radiative transfer

Previous work in framing radiative transfer in terms of Feynman path integrals (FPI) is extended. The path sampling algorithm is extended with a constant time target function for root finding. Benchmarking for root finding schemes is reported. Additional analysis of the path weighting scheme is given. Utilization for the Metropolis algorithm is discussed. A log-normal fit for convergence of the integral sum is found. A visualization tool for attributed path data is presented.
