Abstract

This study evaluates the uniformity and doublecounting behavior of three ray-spawning algorithms— tessellated icosahedron, generalized spiral, and Fibonacci spiral—used for shooting-and-bouncing-ray propagation modeling. Angular separations between neighboring ray pairs were analyzed, and spatial distribution maps of the separation angles were presented. The tessellated icosahedron demonstrated superior uniformity, as indicated by lower maximum-to-minimum separation ratios. Monte Carlo simulations were conducted to estimate the probability of double-counting, using a reception sphere radius defined by the largest separation angle. Results show that the tessellated icosahedron also yields the lowest double-counting probability (~
