Prototyping a WebGPU compute rasterizer for Gaussian Splats at PlayCanvas. No quads, no draw calls — just pure compute shaders blending of splats per tile. Here's the tile load heatmap.

Many 3D generators output Gaussian Splats (3DGS) for fast rendering, flexible deployment, and high visual fidelity. Static 3DGS aren't world models (no dynamics/semantics) but a true world model must allow distilling 3D-consistent representations for any given time step (3DGS/meshes). This post-distillation serves a dual purpose: 1) validates physical consistency of the model. 2) extracting explicit representations avoids continuously running a heavy generator, thus saves compute and facilitates real-time interaction.

🎨 Gaussian Splat rigging opens infinite artistic possibilities! Realtime rendering with my VHS effect in VR 1.5M splats running at 80 FPS in VR with bone-based Mixamo rig animation. Travel into the volumetric worlds of Valerian and the City of a Thousand Planets, reimagined in that bold 1980s sci-fi aesthetic ✨ World Labs Theoretically Media Technical • GPU compute shader skinning (256 threads) • Linear Blend Skinning (LBS) with up to 4 bones per splat • Bind pose capture for accurate deformation • CommandBuffer synchronization for frame-perfect timing Why splats are perfect for comic art I think: Each splat is a volumetric 3D ellipsoid that naturally creates crisp edges and flat color regions—the essence of cel-shading. No complex shader tricks needed. The volumetric representation itself gives you that graphic novel aesthetic. #Realtime #GaussianSplatting #VR #GameDev #Unity3D #VolumetricRendering #ComicArt

🟢 News: GPU compute in the browser is finally real. WebGPU now ships by default in Chrome, Firefox, Safari, and Edge—not a polyfill, not behind a flag. You can run LLMs client-side. Transformers.js and ONNX Runtime already ship WebGPU backends. Eight years of spec work. No more asterisks. 🔗 #WebGPU #GPU #Chrome #Safari #Firefox #Edge

A look at the future of VFX? Testing Gaussian Splats plug-in for After Effects, combined with close to real-time ai transformation with Krea ai and fire/smoke generated with Runway Gen3. This could be camera tracked and comped with real footage.. 😍 #art #ai

Getting a bunch of questions about this! It's a full gpu rendering pipeline with built in shader editor for Rive, which can interleave 2D + 3D. Think WebGPU (minus compute, for now) that runs anywhere, not just the browser. You can implement anything at all. Cell shading. Background blurs. Deformation effects. And yes, even Rive vector components as textures. Shaders are precompiled and ship with your .riv. Minimal runtime size impact. Still WIP.

👀 Ever see a 3D sci-fi energy shield like this? Realtime, interactive (per-tile), procedurally animated, and has layers of shaders with particle effects - I wanted to make something unique and "technically advanced", but also modular for performance scaling. It's straightforward to address individual tiles and hook in your own effects and calls with custom events. I'll be posting this very soon (for Unity URP).

For #acerolafurrychallenge, I opted to make a grass shader I've theorized years: No tesselation, no compute, NOR shells. Just a parallax hex-lattice of randomized ellipsoid grass nubs, all sampling shadows and depth for correct shadows. URP. All drawn via a single cube mesh.

Apple just trained a 3D Gaussian head reconstruction model on 10,000+ subjects. Feed-forward. No test-time optimization. New identity in, reconstructed Gaussian head out. The UV-parameterized Gaussian representation decouples the number of Gaussians from the number and resolution of input images, making it practical to train with many high resolution views. And the heads are not just static either: text-conditioned identity generation, plus blendshape-driven latent animation across identities. We've been building in the 3D Gaussian Splatting space for a while. The gap between "research demo" and "works on real people at scale" is closing fast.
