LOD/mip blur -- any, dynamic radius; fixed sample count regardless. On a quest for faster realtime rendering. > Render texture aside, it's a single pass.

I wasn't planning on doing blur with mips (mentioned something similar in my QT about optimization), but this was my night experiment. It's like Doom 2k16, but I'm trying to be more tricky/efficient. Dynamic 4-sample blur:

🫳 Try the interactive WebGL demo. It should be fast, even running on mobile:

Great as always Mirza! Does it support UI image component?

Thanks, and yes -- it's just a technique/algorithm. It can be used anywhere. 🙂

4-sample, 4k LOD/mip-based blur. + depth attenuation, per-pixel.

Mimicking path tracing in a single pass is no small feat. That variable radius optimization is a serious performance win.

I've come to the conclusion that you have a hyperfocus on creating materials and shaders.

Kingdom Hearts had incredible tech. > On the PS2, around ~2002! Even *the* most basic enemy, a shadow 'heartless', had complex rendering and behaviour [for the time]. Flatten, render -> top-down texture, duplicate intersecting polygons, *then* sample the texture on that geom.

$Unity includes a tool for baking SDF textures: 🧊 I made this experimental shader for fully volumetric glass shaped to any object using a 3D distance texture. Handles layered self-refraction in a single pass (look at the ears, when the model is rotated), + explicit backface rendering via another camera -> texture pass. I don't have clear plans to add this to PRISM, but it's something I wanted to try out as a morning experiment (R&D, rendering/optics, performance -- for later).$

Utter and total insanity(!!!) My vote for most hardcore splat demo ever. DOOM entirely in splats. Sprites, status bar, characters, gun rendering, all splats. Rendering and sorting with WebGPU. Dynamic lighting updating splats in real time. Sparkjs LoD to render entire levels.

FASTER for #Amiga OCS/ECS: switched over to single pass (rather than 4 pass) rendering for car and scenery bobs, giving a noticeable increase in performance. Further evidence for any existing doubters out there that this is definitely not a lazy port from the ST! 😄

okay I got batching working on Nvidia's Motionbricks, and it's still realtime! About 10k generations a second on one 4090, 26x faster than one at a time. You can now have insanely dynamic crowds in your games! opensource:

some progress on SSGI > GBuffer pass with normals and albedo > mipmaps for depth and irradiance (so we can lod sample farther pixels) > horizon based AO and GI (6 rays per pixel, 12 steps) next step is fixing the temporal and spatial noise

In feature film VFX, our lighting teams spend a lot of time shaving off as much render time as possible. Even 1 minute saved per frame adds up. For a 5 second shot, 1 minute less per frame saves you 2 hours of rendering per shot. Our shots are usually a lot heavier than this and our teams usually get a lot more optimization for render times than 1 minute per frame. Some shots can be rendering for up to 30 hours per frame depending on complexity. Large studios have a plethora of optimization tools which shave off a lot of render time from our shots. Rendering technology is always improving, bringing render times down and increasing physical accuracy. Video is of Hyperion with interactive rendering with Pixar's RenderMan XPU renderer, which is up to 5x faster than their older RIS architecture.

Btw I'm working on window blur in niri! Both xray and regular. Xray always "shows through" to the background. This allows it to be very efficient: compute blurred texture only once, then just draw that texture (very cheap). Not a single blur recomputation in this video! #niri

Not quite #screenshotsaturday Finally figured out realtime POINTINESS SHADER! No texture baking or raytracing, just a whole bunch of precomputed vertex values and crazy shader math. Works instantly on any mesh. Pointiness -> edge highlight + wear + occlusion and even bevel!🤓

Minecraft is now rendering on a PS5 emulator. It's still heavily glitched, but this is another meaningful step for PS5 emulation. Current progress: • Main menu boots • World loads • Some blocks, like beds, render correctly • Basic rendering pipeline appears functional The biggest issue now seems to be texture handling. The PS5's texture memory still isn't being translated correctly into Vulkan images, causing most textures to break. It's far from playable, but every correctly rendered object is another clue that the emulator is moving in the right direction. Credit: discord/Arbis
