    Vulcan is a driver-level API. It competes with DirectX and OpenGL.

    CUDA is a language you write kernels. It competes with OpenAI's Triton language.

    Here's what CUDA looks like: https://github.com/tspeterkim/flash-attention-minimal/blob/m...

    This is what Triton looks like: https://triton-lang.org/main/getting-started/tutorials/06-fu...

    By contrast Vulcan looks like this: https://github.com/KhronosGroup/Vulkan-Samples/blob/main/sam...

    (It's true to some extent that maybe you could use Vulcan shaders to write deep learning kernels, maybe? I'm not aware of anyone doing it though)

    • Project mention: Voronoi Diagram and Delaunay Triangulation in O(nlog(n)) (2020) | news.ycombinator.com | 2023-10-25

    Interesting question! By virtue of being a tree, the MST produces at most 3 edges coming out of any vertex, so this should be the same in 3D. The MST then adds (sometimes) a 4th edge, so, although you could build both graphs in 3D space, you would still end up with 4 edges coming out of any vertex, I think.

    In 3D space the Delaunay triangulation would produce a bunch of irregular tetrahedra, so the edges coming out from every vertex would vary between a minimum of 3, and a maximum of 12, if I get it right (ref: [1] :-).

    The 3D Voronoi cells are another story... I found some implementation that you can play with to see how it looks [2] [3], each cell is of a shape called "convex polytope". It feels like these cells are packed like each of the sub-cubes of a rubik, but I'm not 100% sure :-) ... if that's true, you could jump from each vertex to the next in at most 17 directions? (hand-waves :-p)

    • Project mention: Show HN: Realtime Global Illumination on Older Hardware [video] | news.ycombinator.com | 2023-07-24

    Hi everyone,

    A few months ago I posted here on HN about my open source 3D rendering engine. Since then I've been working on the new version which implements additional modern graphics techniques while still running on older GTX 10 series hardware.

    This includes emission mapping, FXAA+TAA, better mesh LOD generation and selection, but the biggest one was an overhaul of the global illumination system.

    The global illumination overhaul was the biggest aspect of the new release. The goal was better visuals than the previous version while maintaining equal performance. I wanted to outline how it works and what I had to do to make it work.

    = How It Works =

    * Direct lighting: Handled using standard rasterization pipeline with cascaded shadow mapping

    * 2nd bounce of light: Approximated by a set of virtual point lights

    * 3rd bounce of light: Not directly simulated but shadows are tapered to prevent harsh cutoff. VPLs can also be placed in open spaces to help spread light where it wouldn't be able to go without a true 3rd bounce.

    * Adaptive sampling: maximum of 4200 virtual lights per frame are selected. Each pixel computes lighting using between 1 and 10 random samples based on object's distance to camera and whether or not the lighting history was recently discarded for that pixel (recently discarded = temporarily sample more heavily).

    * Spatial resampling: each pixel can look at a few of its neighbors each frame. If the neighbor is a good fit it will merge that neighbor's samples into its own to increase the effective sample count.

    * Denoise and temporal accumulation: 2 level wavelet denoiser combined with temporal accumulation to get rid of most noise and stabilize the image even when in motion.

    = Maintaining Performance =

    There are a few key ways that this version is able to both look better yet have the same performance as the previous version on the same hardware.

    1) Reuse as much data as possible between frames. This is where the temporal accumulation aspect comes into play.

    2) VPLs are updated slowly over many frames to prevent any single frame from halting the system.

    3) With thousands of VPLs per frame, they can't all be factored in for each pixel. It's too much work. The approach was to instead sample from the set of VPLs randomly, reuse as much data spatially as possible, denoise the result and temporally accumulate 1 second worth of frames.

    I'm very happy with the results! Roughly the same performance as the previous version but better visuals.
