And one more video :)

Started with the feeling that it would be a waste to just throw my froxel code out of the renderer, and ended up on a week-long journey into cloud and sky rendering. With great support from @CorporateShark, I got async compute working in LVK, without which I'd never have hit the 2ms performance (github.com/corporateshark…, production-ready implementation coming soon). The model of "Lowpoly Steampunk Airship" (sketchfab.com/3d-models/lowp…) by Lhyo (sketchfab.com/Lhyo) licensed under CC-BY-4.0

@chena_cpp @CorporateShark I still need to improve the filter and wash out the rest of the artifacts caused by the regular grid structure. Planning to play with neural rendering approaches there. Stay tuned!

@chena_cpp @CorporateShark Analytically, we calculate only these 8 light sources per fragment, plus 1 unconditional directional light — the “sun” (turned off in this scene). Diffuse lighting goes into a light buffer, where a depth-aware bilateral filter is applied. The SH are trilinearly blurred for free.

My modest attempt at clustered lighting with irradiance volumes. Fully GPU-driven Vulkan powered by @CorporateShark’s LVK. Insanely fast! 256 light sources at 0.43ms per frame.

@chena_cpp @CorporateShark Dynamic like that:

@rokuz7 @CorporateShark Cool, Is the light dynamic?

@CorporateShark @chena_cpp 2k. rtx 4090

@chena_cpp @rokuz7 What was the resolution and the GPU?

@chena_cpp @CorporateShark Yes

Vibe-coded somewhat useful tool (at least for me). Now I have fine-grained control over what Claude generates in my project, instead of accidentally discovering that it hardcoded something silly many commits ago. github.com/rokuz/gitloco — open source and MIT-licensed.

Finally got a mobile device to launch @CorporateShark ‘s ray tracing demo in lightweightVK

@SaschaWillems2 @VulkanAPI Looks cool. Any chance we set up time frame? E.g. for the last 3 years?

Added extension detail pages to my @VulkanAPI #Vulkan gpu database. Should make it easier to pass around coverage info via links, e.g. vulkan.gpuinfo.org/displayextensi… Links can be reached directly from the global extension listing.

See you at #SIGGRAPH2024 !

Played today with new Surface Pro 11 on arm64, Vulkan capability viewer found “Microsoft DirectX 12” GPU. Does it look like DX12 has Vulkan under the hood now? 🙃

FYI my presentation on Vulkanised’24 “MoltenVK for Advanced Vulkan Renderers on macOS” youtu.be/hwsiOZf_dNs?si…

@biovf @CorporateShark Now you can do it :) github.com/corporateshark…

@rokuz7 @CorporateShark I would love to see a Streamline capture of that! 🙂

Just launched LVK on Mali Immortalis-G715 with @CorporateShark Amazing results for fully bindless Vulkan 1.3 rendering on mobile device.

Finally, LightweightVK on Android - github.com/corporateshark… Took a while to implement it. Too many complications, including fightings with Android OS permissions, workarounds for bugs in Vulkan driver and fixes in glslang

Finally launched our Vulkan 1.3 bindless rendering on macOS via MoltenVK. Too many issues if you need uniform bindings aliasing that's not supported in Metal. Looking forward to telling about it in "MoltenVK for Advanced Vulkan Renderers on macOS" on Vulkanized 2024.
