There's a neat short paper from Eurographics this year that evaluates how well microfacet shading models actually predict measured reflectance. The answer is: not nearly as well as one would hope! (1/3) ssteinberg.xyz/2026_surface...

wave_tracer 0.1 released wavetracer.dev wave_tracer combines path tracing and wave optics in a novel way, for practical general-purpose wave simulations across a variety of EM modalities and applications.

I stand (sit) behind this: alecjacobson.com/weblog/siggr... I will also warn Israeli potential attendants (meaning any civilian connection to Israel, like familial relations, loose as it may be) risk *getting kidnapped or worse*. Yes, even if you travel with a foreign passport, you may be targeted,

To be presented in SIGGRAPH Asia: A path tracing-compatible formulation for general-purpose wave transport. See how light transport, under rigorous Wigner optics, can be done practically for optical, long-wavelength (RADAR/cellular), and acoustics applications. ssteinberg.xyz/2023/03/27/r...

A Generalized Ray Formulation For Wave-Optics Rendering

Under ray-optical light transport, the classical ray serves as a linear and local "point query" of light's behaviour. Linearity and locality are crucial to the formulation of sophisticated path tracin...
