coming soon👇 Atmosphere²

"Hello, World" by @astro_reid and @NASAArtemis in #Blender
Simulated with the upcoming Atmosphere² Addon.

Sun, Moon and planet positions are calculated by the date & time, and the position of the camera is driven by the Artemis II Ephemeris file.
The lighting is physically simulated from the Moon and Sun spheres, in real-time.

I had to bump up the Exposure value to see this result.

[Physical Addons @PhysicalAddons]

Exactly this.

[NASA Earth @NASAEarth]

That's us! 🌍

The Artemis II crew captured beautiful, high-resolution images of our home planet during their journey to the Moon. As @Astro_Christina put it: "You guys look great."

@FlippedNormals We can only imagine how intense this period has been. Hope when the tides calm, you get to stand on your feet and enjoy what comes next.

This was not a decision made lightly. Over the last few years, the costs of maintaining a store with thousands of creators have increased significantly, while earnings have decreased. 1/7

I accidentally created an optical illusion in #Blender while implementing a hexagonal texture de-tiling.
The hex edges appear to slightly bend.

POW development has been quietly cooking for 3 weeks. Time to talk about it.
Our new intern Sphynxcolt — from our own Discord community — is working hand in hand with Mārtiņš on a new LUT-based wave system. No more hardcoded limitations. Future-proof architecture. Room to grow.

Get ready for some spectral eye-candy!

Teamwork 💪 @samuel_krug

All over the place this week - my nameday off midweek, @_martinsh presenting Flow in Tartu.
Second week of IG community picks - learning how time-consuming proper curation is: https://t.co/OhVUX8qlby
@_martinsh working on clouds. I'm wrapping LIAA yearly reports.

[80 LEVEL @80Level]

.@iamcosmoloop presented a beautiful real-time water shader made in Blender, which delivers refraction, underside refraction, lights, and shadow interaction.

Enjoy: https://t.co/t8V0pmoxXw

[Karlis Upitis @_karlisup]

This week: moon implementation, atmospheric refraction for celestial bodies, and depth sorting for stars/sun/moon/earth.

Still rough around the edges (missing textures, light emission, depth sorting bugs), but the foundation is solid. #atmosphereV2

[Mārtiņš Upītis 🇱🇻 🇺🇦 @_martinsh]

Two very much exaggerated cases of the green flash. The distortion of the sun and atmosphere is caused by the thermal inversion, so sometimes it bounces the ray creating mirages (same way mirages form on hot ground or asphalt) #b3d

[Physical Addons @PhysicalAddons]

"Taking a break from clouds" @_martinsh said.
48 hours later: atmospheric refraction with temperature gradients running in real-time.
...And that's why ladies and gentlemen I handle the business side.

[Mārtiņš Upītis 🇱🇻 🇺🇦 @_martinsh]

Atmospheric refraction in #Blender

I added pressure and temperature gradient to my atmosphere shader. The sun is spectral and IOR variation makes the ‘green flash’ possible.

Animation starts when sun is at horizon. Which means that the whole animation happens behind horizon.

[Physical Addons @PhysicalAddons]

@polyhaven Thanks for the shoutout! Retro-future + atmospheric lighting = *chef's kiss*. If we were in our early twenties with unlimited time, we'd absolutely jump in and try to snag some prizes 😄. This time we'll be cheering from the sidelines.

Further experiments with cloud rendering in #Blender
I added a custom, spectral phase function. It is a LUT calculated with my MIE plotter in shadertoy.

Multiple scattering is based on Delta-Eddington two stream approximation, a fast, accurate method in atmospheric physics for calculating radiative fluxes (light transfer) in scattering atmosphere and clouds.
