It uses WebGL 2.0 compute shaders to perform per-splat sorting and alpha blending on the GPU, enabling real-time display of millions of semi-transparent ellipsoids. The application also functions as a drag-and-drop converter that transforms .ply files from 3D Gaussian splatting software into the optimized .splat format for web rendering. The viewer provides full camera navigation through keyboard, mouse, and touch gestures, and includes a camera view manager that saves, shares, and cycles through pre-loaded positions. Specific viewpoints can be encoded into the page URL for direct sharing or bookmarking, and numbered keyboard shortcuts allow instant switching between saved camera positions. The entire application is delivered as a single self-contained HTML file with no build step or server-side dependencies, loading directly in the browser. ## Tags ### Part of an Awesome List - [Gaussian Splat Rendering](https://awesome-repositories.com/f/awesome-lists/ai/gaussian-splatting/gaussian-splat-rendering.md) — Renders 3D Gaussian splatting scenes by projecting millions of semi-transparent ellipsoids via WebGL shaders. - [3D Model Drag-and-Drop Loaders](https://awesome-repositories.com/f/awesome-lists/devtools/drag-and-drop/3d-model-drag-and-drop-loaders.md) — Loads 3D Gaussian splat files by dragging and dropping them directly into the browser viewer. - [File Format Converters](https://awesome-repositories.com/f/awesome-lists/ai/gaussian-splatting/file-format-converters.md) — Converts .ply files from Gaussian splatting software into the optimized .splat format via drag-and-drop.
