aframe-gaussian-splatting-component

This component is an A-Frame implementation of real-time rendering for 3D Gaussian Splatting for Real-Time Radiance Field Rendering.
This code is derived from the WebGL implementation developed by antimatter15.

Demo pages

Needs few seconds to load splats.

Demo: https://quadjr.github.io/aframe-gaussian-splatting/
Cutout demo: https://quadjr.github.io/aframe-gaussian-splatting/cutout-demo.html

Properties

Property	Description	Default Value
src	url of splat or ply file	train.splat
cutoutEntity	selector to a box primitive that uses scale and position to define the bounds of splat points to render
pixelRatio	Pixel ratio for rendering. Reducing the value decreases the resolution and improves performance. If a negative value is set, the device's native value will be applied.	1.0
xrPixelRatio	Same as pixelRatio. Applied to XR devices.	0.5

Example custom scan to gaussian splat workflow

Use a service such as https://lumalabs.ai/ to process a scan into splat (an alternative is https://poly.cam/)
Go to download dialog and choose Gaussian > Splat (which will download a .zip file with .ply file inside)
Convert the .ply to .splat in the browser using this site: https://splat-converter.glitch.me/ by @akbartus (repo https://github.com/akbartus/Gaussian-Splatting-WebViewers/tree/main/splat_converter)
Use resultant .splat in the A-Frame scene with this component

Usage

Browser Installation

Install and use by directly including the file. About the splat file, please refer antimatter15.
