I wrote a post + interactive tool on the RTX shader binding table to explain it across DXR/Vulkan/OptiX willusher.io/graphics/2019/…. With the tool you can setup an SBT, scene and call trace ray to see what shaders are called! At the end I bring the SBT back to the CPU with Embree

Announcing - WebGPU Puzzles: Learn GPU Programming in Your Browser It's a web app that let’s you practice writing GPU compute kernels using WebGPU - runs 100% in the browser, locally on your GPU (even tiny integrated laptop GPUs).

⚡ Ray Tracing + 3D Gaussians = New Possibilities! Gaussian splatting is limited by rasterization—our #SIGGRAPHAsia2024 paper shows how to ray trace instead, enabling reflections, shadows, fisheye cameras, and more. The most important (and hardest!) part is making it fast. (1/N)

@_wusher I hacked it like this
Marcin Ignac@marcinignac

@unconed I just attached second canvas with WebGPU context (not doing much, just choosing render target) in the same window and made both run on the same RAF 🤣. But the WebGL to Metal translation make things hard to read sometimes. Shader profiling is useful though.

Trying to get Metal Debugger working with WebGL this weekend following this tip aiming at WebGPU x.com/slimbuck7/stat… Promising so far. Can't believe how I survived 10y without such detailed timing. Envy native devs where this is day to day standard.

For those interested in doing metal captures for WebGPU (cc @Cody_J_Bennett, @munrocketx), these are the steps I followed: gist.github.com/slimbuck/ec450…

C++ code is out! The Signed Heat Method has been added to geometry-central. In 3D, compute generalized SDFs to point clouds, triangle meshes, and polygon meshes. The method should "just work" on geometry with holes, intersections, nonmanifold-ness, etc. Links below 🔽

🥳 I just open-sourced the web port of Open Image Denoise: github.com/pissang/oidn-w… It has been integrated into Vector to 3D for weeks. It significantly reduces users' render time and usually produces very clean results. Huge thanks to the hard work of the OIDN team for creating such a magical denoising library. Also, thanks to @maxliani for the inspiration to port OIDN to other platforms. #webgl #webgpu #tfjs

The red pixels here show the incomplete rays, which are terminated and filled in by the model once 85% of pixels are complete

Ending traversal early and filling in the image improves overall rendering perf by removing long tail rays, further reduces the amount of data to be processed, and still provides a good image Try the demo: #dataset=magnetic" target="_blank" rel="nofollow noopener">ldyken53.github.io/TVCG-progiso/#… & grab the code: github.com/ldyken53/TVCG-… !

Excited to share some excellent work with Landon Dyken and @sidharthIO : willusher.io/publications/p…, we extend our #WebGPU progressive raycasting pipeline w/ ML image completion to stop raycasting early and complete the image with ML! It can still run in the browser w/ ONNX WebGPU!

Here's an amazing new SIGGRAPH paper from @daseyb/@ejdeon/@tunabrain/@wkjarosz that achieves one of the holy grails of modern rendering: unifying microfacets+volumes for light transport. Along the way the authors make a lot of neat observations and unlock cool new abilities too!
Dario Seyb@daseyb

I'm excited to share our #SIGGRAPH2024 paper on unifying stochastic representations for light transport: cs.dartmouth.edu/~wjarosz/publi… We show how to use stochastic implicit surfaces to describe microfacet surfaces and participating media (and a bunch of new things in between).

I wrote about using CMake, VSCode & wasm-tools to build/ship/debug a C++ #WebAssembly module that fits into a larger frontend app: willusher.io/blog/build-shi… Set breakpoints, inspect vars, and reconstruct stack traces from prod! Tell me about the cool stuff you're doing with #Wasm!

If you are still using std::unordered_map, worth checking for faster replacements. std is usually 2x-3x slower, up to 87x slower in worst case (vs best). jacksonallan.github.io/c_cpp_hash_tab…

@iquilezles Beautiful! It's awesome to see more WebAssembly driven rendering & modeling apps on the web

After 15+ years of exploring "Easy 3D" through SDFs, we've now put #ProjectNeo together, which you can try today in beta here: projectneo.adobe.com
