Supernova explosion #webgl #threejs #loop

DO NOT google "C strings" and click Images! I repeat, DO NOT!

@SebAaltonen Yes, please.

I will be benchmarking against Three.js soon. Let's see how well that goes :) Ours is WASM + WebGPU.

After porting HypeHype shaders to our new project (and from GLSL to WGSL), I restored gather4 and fp16 optimizations... Biggest gains: SSAO: 0.992ms -> 0.555ms (-46%) Lighting: 0.149ms -> 0.108ms (-28%) Total frame time in test scene = 1.16ms (M3 Max)

@Rainmaker1973 The universe is fundamentally integer. There are a finite number of Planck cubes, which means a limited number of digits of pi (which can be thought of in integer form) to calculate volume. And you cannot have a fraction of a quark or lepton, so … integer.

@mrdoob @_Ellyson_ Incredible

Still tweaking the API, but baking lightprobe volumes is fast and the results are looking great. Aiming to ship this in Three.js r184 later this month.

Lacuscular. ❤️

@lisyarus We want 5-gons in list: dodecahedron and truncated icosahedron.

Pretty sure you really wanted to see all the 14 uniform polyhedra with only regular 3, 4, 6 or 8-gons as faces today

@SoftEngineer @threejs Will you opensource it?

The difference between @threejs and Shade is pretty massive. Shade is an entirely new engine written from ground up😅 Shade is a deferred renderer, it's fully GPU resident, it uses a vizibility buffer. It's got a built-in post-processing stack written from scratch as well. There's clustered lighting, order-independent transparencies, ray tracing, advanced texture filtering, occlusion culling and more. Regarding stills - when I started Shade, one of the main goals was to offer a turn-key solution. I was always frustrated with @threejs and Unity game engine by the amount of tinkering the user is expected to do to get a good looking result. Unity got better at this over the years, but far far from perfect. I wanted Shade to "just work" and look good doing it. To that end, all of the screenshots and videos don't have any special settings. It's just engine defaults. For example, pretty much everything looks better with some ambient occlusion (AO). You can bake it into your textures, but that's effort on the user's part. Screen-space AO works pretty well, so it only makes sense to offer it by default. However, even with just the AO there's a lot of effort to get to work well and fast, there are different algorithms and optimizations. Shade comes with best in class GTAO implementation that is fully PBR-aware, so you get good looking results every time. Another example is automatic exposure. Without it - the user has to tweak lighting to make sure the scene is not too bright and not too dark. Auto-exposure just takes care of it. You can disable it, or you can compensate the exposure via settings to make the overall appearance darker or brighter, but the default works well and looks good. Again, the feature is not a prototype but a robust best-in-class implementation. In fact, it's near identical to Unreal's system. There are lots of good looking demos in three.js, but if you just load a model, and add a light - it will look pretty underwhelming. I wanted to make the user not have to care about what's under the hood, import your assets and Shade will make it look good by default.

Wat

@fernandojsg I want to try. I played doom more than in quake in my childhood.

Almost there. A few tiny details left, but the Doom port to JavaScript + Three.js is basically done. ~27k lines of code, ~200KB gzipped

MetaSpot: Spot constructed from metaballs (technically smooth-min blending of implicit ellipsoids).

Fun shader platform by XoR. I am in trending today 😁

The default avatar on FragGoord is now procedurally generated with a shader

@XorDev Wow and MacOS bugs fixed too.

FragCoord kind of works on phones now

@JohannesVuorine @SebAaltonen @HypeHypeInc can you sell old hypehype engine to flutter team? Dart infrastructure much better than react-native. As I understand your new hypehype engine will be completely new.

@HypeHypeInc @SebAaltonen you closed your platform so violently. Maybe you will opensource your low level graphics layer? At least some unfinished prototype with Dart.

@XorDev It’s cool! Thank you!
