Introducing WebGPU-Bench: A WebGPU Microbenchmark
Introducing webgpu-bench, the micro-benchmark suite behind Web3D Survey’s GPU benchmark, with measurements of shader operations and code patterns available through a webpage and CLI.

How to Use Three.JS's new Native Gaussian Splats
How to use Three.js's native Gaussian Splatting support (GaussianSplat, SPZLoader). Load .spz/.ksplat/.splat/glTF splats, pick a file format, and run a capture-to-render workflow with Polycam, Luma AI, Scaniverse, and SuperSplat.
Running LLMs in the Browser with Three.js
A tour of how language models generate text, how GPT-2 and newer Phi and Qwen architectures differ, and how Three-LLM implements their inference graphs with Three.js TSL compute shaders.
Adding Global Sort to Three.js Gaussian Splatting
How GaussianSplatGroup gives Three.js a global back-to-front sort across multiple Gaussian splat clouds, using transform indirection, a WebGL2 CPU fallback, and grow-only buffers so camera and matrix updates stay cheap.
Neural Texture Compression in Three.js
A small multiresolution feature grid plus a tiny MLP decoder that replaces a stack of correlated PBR textures with one compact, GPU-decoded representation. Named channels with their own activation functions, built on new fp16/half-precision support in TSL, and demonstrated on a MeshPhysicalNodeMaterial. The format is material-agnostic.
Fine-Grained Shader Validation in Three.js
How Three.js now validates individual TSL shader expressions on WebGPU and WebGL2, with numeric diagnostics, deterministic input sampling, and support for vectors and matrices.
Neural network basics, for graphics people
A short reference on the neural-network vocabulary used across the neural texture, neural material and neural appearance posts — MLP, weights and biases, ReLU, forward pass, loss, gradient descent, backpropagation, Adam, latent vectors, feature grids and decoder networks — explained once, concretely, so those posts can link here instead of re-deriving it.
Adding Native Gaussian Splatting Support to Three.js
How I added Gaussian Splatting to Three.js with WebGPU, TSL, a reusable GPU counting sort, SPZ v3/v4 and interoperability loaders, and SH1-SH3 view-dependent color.
Reporting Web 3D Capabilities on a Budget of $3 a Month
The architecture behind Web3DSurvey, two Cloud Run services, a partitioned BigQuery store, and a transparent JSON cache that let me report real-world WebGL and WebGPU support for a few dollars a month.
Rendering Real-Time 3D Before GPUs
How I built real-time 3D rendering on a slow 486 with only 256 colors in VGA Mode 13h, using fixed-point math, palette quantization, matcap-style Phong lighting, and x86 assembly.
Web 3D Survey v2
Web 3D Survey v2 rebuilds the site on TanStack Start, adds homepage support summaries, WGSL and adapter reporting, browser capability stats, and a live /machine report.
Adventures in Fluid Simulation
I spent ten years building fluid simulation tools for VFX: a three-day Stable Fluids prototype, sparse level sets for Scooby-Doo 2, tetrahedral and vortex solvers at Exocortex, and three pieces of my software on Harry Potter and the Deathly Hallows.
