Geometric Optics Approximation Sampling: A Far-Field Reflector-Induced Transport Framework
Zejun Sun, Guang-Hui Zheng
We develop a far-field geometric optics approximation sampling (GOAS) framework for constructing direct samplers from target measures. The method exploits the connection between th…

Geometric Optics Approximation Sampling: A Reflector-Induced Transport Map Framework
Zejun Sun, Guang-Hui Zheng
In this paper, we propose Geometric Optics Approximation Sampling (GOAS), a reflector-induced transport-map framework for sampling from target measures. Once a reflecting surface i…
