Super excited to announce that ring worlds now also have an atmosphere :) #bevy #gamedev

Physics time warp! Another advantage of moving all physics systems to Bevy's fixed-rate schedule is that we can speed up time even with Avian's rigid body physics active. Any speed multiplier world work here and the behavior is the same as in real time. #bevy #gamedev

Continuing the instanced rendering arc with terrain scatter. It doesn't look that fancy yet and it's lacking any kind of artistic control. But it's a start! #bevy #gamedev

And here's the new ring debris rendering together with the rest of the planet! I also added raymarching for the ring dust. 🪐 #bevy #gamedev

And here are the planetary rings with frustum culling and level of detail implemented! This is a total of 4M objects (~1M after culling). #bevy #gamedev

Let's move the planetary ring debris fully to the GPU! Today I worked on a proof of concept rendering a million points. Single-precision floating point again makes this harder than it should be. The solution? Use a Taylor series approximation close to the observer, where all the debris is. #gamedev

The ring shadows are done by intersecting a ray to the sun with the ring and then sampling the 1D ring texture at the hit position. #gamedev

Spent a bit of time rewriting the ring texture system. The ring textures are now generated on the GPU together with the rest of the terrain data, instead of being loaded from memory. This allows for much quicker iteration time when working on those textures :) #bevy #gamedev

Sketch of a tidally locked ice world. I quite like the surface texture of the ice here :) #bevy #gamedev

This was supposed to be a moon but it ended up looking more like a planet. Trying a new method here to get more color variation. #bevy #gamedev

Messing around with noise functions for the desert planet I noticed that faking dried up rivers and lakes is just a matter of layering and warping noise. No complex simulations required :) #gamedev

how about some procedural volcanoes

Somehow got inspired to improve the looks of the "default moon" in the game. This is the first time I'm using a grid-based approach for the craters. That way every generator invocation only needs to iterate over the nine closest craters to calculate their height offsets. #bevy #gamedev

Investing some time in cloud rendering again 🌤️ Here's a small improvement to the density function that makes the cloud layer thicker and uses an additional 3D texture to give it more detail. #bevy #gamedev

Finally added planetshine! Now planets and moons will also illuminate the rocket based on how much light they receive from the sun. Really helps tie the scene together. #bevy #gamedev

With the latest driver update nvidia threw a curve ball my way. The terrain suddenly rendered with black hexagons and the generated data of some planets lost a lot of resolution. #gamedev

And here's the first dwarf planet! It's far from the sun and features a "sea" of frozen nitrogen. I like how the very thin atmosphere makes it look much more dramatic. #bevy #gamedev

hell yes this was fully intentional and not at all the result of putting a minus in the wrong place #gamedev

And another one! I quite like the wavelike pattern on this one. It's also the first to feature the new procedural impact craters. #bevy #gamedev

More experiments with canyon features! This time with a slightly different approach which allows making them even larger. I like how those help sell the "icy moon" look. Poor moon has been through a lot though :( #gamedev #bevy

Finally sat down and worked through the math to generate realistic looking crater geometry. Now nothing will stop me from spamming those when creating new planets and moons. #gamedev #bevy

Started working on a new moon for one of the gas giants. I really like how adding local surface features helps to add some character. #gamedev #bevy

Trying to place some canyons on the surface of the moons and uhmmm

Literally all I want is to make an impact in this world Some experiments with producing impact craters in the terrain generator :) #bevy #gamedev

I've been quiet for a while again, but lots of things have been happening behind the scenes! Just not much that would make for flashy pictures. Now I'm looking forward to positing more about the progress again :) #bevy #gamedev

With the added transparency and light absorption, the water shader now passes the "do I want to go for a swim there" test :) Next, I finally need to address the texture tiling. #bevy #gamedev

Managed to get the depth texture into the ocean shader. This felt super hacky with the higher-level material system but should allow for some nice transparency effects. #bevy #gamedev

I added the option to output an emissive texture from the terrain generator. Here's a new moon to showcase the effect 🌋 #bevy #gamedev

Many improvements later, here are some more impressions from the new volumetric cloud renderer. #bevy #gamedev

First look at the volumetric clouds! I pushed this out for quite some time but am happy to see that they are finally on the horizon. #bevy #gamedev
