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.

Tasty too

I stand (sit) behind this:

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,

Couldn’t get it faster with quantization or other tricks. I am also sorting the 8 nodes by distance to AABB. Both ray and cone performance has improved dramatically (traversal is virtually negligible compared with intersecting meshes), so not looking at it further.

Literally spent a couple of days on it. My motivation is also not rays but elliptical cones (for wave optics). A BVH does significantly better than a kdtree for cones, so I also put together an 8w BVH.

Yes. I’d also assume it’d be different on a GPU.

Exactly what I found actually. Compressing the nodes reduces performance even with moderately complex scenes. Uncompressed 8w nodes is fastest.

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.

Happy to announce that I have joined UWaterloo as assistant professor. If you are interested in doing a PhD in rendering or light transport, check out ssteinberg.xyz/students.

A Free-Space Diffractions BSDF. This paper addresses the problem of simulating the diffractions ("bending") of light around geometry and obstacles, in an efficient manner with ray tracing.
