    I don't really do the social media thing very much anymore, and I don't anticipate posting much here in the foreseeable future. You can keep in touch at: bsky.app/profile/geomet… Or, as always, what I'm up to on my website: geometrian.com

    Spreading the raytracing religion! 👁️ ☀️ ↘️ ↗️ 🫖 (My square at the Forest Grove sidewalk chalk art festival last weekend. Yes; I am *absolutely* dorky enough to make over-the-top pathtracing propaganda.)

    One thing that has always bothered me is that the Phong BRDFs don't maintain energy—so I wrote a paper (with @cem_yuksel) about how to fix them! Please enjoy this comparison from our paper, and check out my lightning summary video at the project homepage: graphics.geometrian.com/research/norma…
    Figure 5 in our paper.

    Our HPG 2020 paper/talk, "Efficient Adaptive Deferred Shading with Hardware Scatter Tiles" is up: graphics.geometrian.com/research/dacs_… We give tips to vendors about implementing our HPG '18 paper "Deferred Adaptive Compute Shading" in hardware. Core to the idea is interlocked, on-chip tiles.
    Scatter tile (Fig. 3).
    Scatter tile shading order (Fig. 4).
    DACS vs. VRS image quality comparison (Fig. 6 partial). The globally optimal VRS shading rates were used, even!
    Screenshot from presentation, discussing scatter tiles.

    Preprint + supplemental is up for our @EGSympRendering paper "Spectral Primary Decomposition for Rendering with sRGB Reflectance": geometrian.com/research/index… Spectral reflectance for any sRGB triple without any colorimetric error! (E.g. for using RGB assets in spectral renderers.)
    Title, author, teaser for paper.
