Description

Wave Tracing: Generalizing The Path Integral To Wave Optics is a Eurographics 2026 conference talk recording on YouTube by Shlomi Steinberg with Matt Pharr listed as co-presenter material on wave-optics simulation. It bridges Monte Carlo path integration with practical wave effects.

The talk contrasts bilinear interfering-path formulations with a weakly local incoherent wave-tracing approach built from Gaussian beams and elliptical cone proxies. Examples include diffraction phenomena and wireless coverage scenarios where classical ray optics alone is insufficient.

Researchers and advanced rendering practitioners studying physical light transport beyond geometric optics are the core audience. Background in path integrals and basic wave optics is assumed.

The recording is free on YouTube as a single conference session. Steinberg and Pharr's wave-tracing line of work is discussed in research circles spanning rendering and optical simulation.
