What is Spark?

Gaussian Splatting is a technique for rendering photoreal 3D scenes captured from images. Spark implements an advanced splat renderer for Three.js, the most widely used web 3D library — so developers can drop high-fidelity splat scenes into browser-based 3D experiences using tools they already know.

Who is it for?

Web and 3D developers who work with Three.js and want to display Gaussian-splat captures — for product visualisation, virtual spaces, or interactive photoreal scenes on the web.

Key characteristics

• Gaussian Splatting renderer targeting Three.js.
• Focus on real-time, high-quality rendering in the browser.
• Written in TypeScript; MIT-licensed.

Pros

• Integrates a cutting-edge rendering technique with a mainstream web 3D stack.
• Permissive MIT license makes adoption straightforward.

Limitations to weigh

• Gaussian splatting is graphics-heavy; performance depends on scene size and the user’s device/GPU.
• It targets a specialised use case — you need splat data to render, and familiarity with Three.js helps.
