EmberGen 2 LPV Cloud Rendering R&D EG 1 could never dream of this many voxels at this rendering quality. Oh how far we have come!

Real-time spectral rendering of the atmosphere using Radiance Cascades with rainbows and refraction. Light paths are allowed to bend and create complex dispersion as well as atmospheric lensing.
Wave Cascades: A wave-optical extension of Radiance Cascades for real-time simulation of Lorenz-Mie scattering and Lorenz-Mie-Fresnel diffraction. Fully spectral Mie LUT is computed in real-time (white=measured, green=computed), and I sample it with UHRC which is fully spectral.

Still tweaking the combustion solver in EmberGen 2. A bit closer to photo-realism as well, particularly at the end.

Based on my recent work for real-time Lorenz-Mie scattering and spectral volumetrics, I think it would suit well for atmosphere rendering in the style of Gran Turismo. Has anyone tried recreating their datasets, or better, results, also to compare? Want to try this in real-time.
Replying to @CodyBennett
Mie scattering is wavelength-dependent and varies over altitude and humidity, as described in "Physically Based Real-Time Rendering of Atmospheres using Mie Theory" and Gran Turismo 7 2023 GDC presentation. This phase is nice on the ground but doesn't hold up at higher altitude.

Wife told me these wouldn’t fit. Little did she know I had trained for this moment for years.

i made a puzzle game where you bend light with prisms, lenses, black holes there's 30 levels for you to play it's called Prism Rules, it's out now, i hope you'll enjoy :]
i'm working on a game prototype where you use mirrors / prisms to bounce light around and solve puzzles not sure if this is something? think you'd have fun playing this?

This is the clarity we've been crying out for. But it's a poisoned chalice. This is a 10X cut to claude -p disguised as a monthly bonus. Anthropic is discouraging any kind of programmatic usage. And that's fine - no subsidy lasts forever. But it's time to try Codex.
Starting June 15, paid Claude plans can claim a dedicated monthly credit for programmatic usage. The credit covers usage of: - Claude Agent SDK - claude -p - Claude Code GitHub Actions - Third-party apps built on the Agent SDK

The Mother of All Games Scorched Earth, by Wendell Hicken, was released as shareware in 1991. Not easy on the eyes, but one of the best multiplayer games ever! It let you customize everything - from gravity, wind, and meteor showers. Building on earlier games like QBasic Gorillas, it took the concept to a new level, supporting up to 10 players with far more complexity and variety. You could set the angle and power to aim, combined with a wide choice of weapons (unlike the banana in QBasic Gorillas). Computer-controlled enemies could be set from difficulty 1 (Moron) to 10 (Cyborg). No other game has named its lowest difficulty level so perfectly! Here’s to Wendell Hicken - thank you, wherever you are!

I learned a few months ago from Dr. Harmon that you can actually see Earth’s shadow in the sky during sunrise or sunset. I had no idea that was even possible until he mentioned it. Today, I looked out the window and the sky looked exactly like what he had described: a bluish band near the horizon with a soft pink layer above it. I checked with him, and my guess was right. It was Earth’s shadow and the Belt of Venus. Even though we can’t see it anymore, its light is still traveling through the atmosphere. The Earth itself blocks part of that light, casting a huge shadow into the air opposite the sunset. That shadow appears as a dark, bluish band rising in the sky. This is Earth’s shadow. The pinkish layer above it is called the Belt of Venus. It is sunlight that is still reaching the upper atmosphere and getting scattered, giving it that soft pink color. There are so many subtle celestial moments happening around us that we don’t even realize are there!

I'm trying to figure out where to live next, and one big consideration is the climate. So naturally I made a tool that represents monthly average temperatures for cities as 3D rings so they can be compared more easily. Check it out: awjuliani.github.io/weather-…
