Shaders is an open-source library that provides production-ready WebGPU shader visual effects packaged as components for modern web frameworks. It includes a browser-based design editor to visually customize, create, and export shader effects directly into code.
COBE is an ultra-lightweight, zero-dependency WebGL globe library that renders interactive dotted 3D globes. In version 2, it integrates with the CSS Anchor Positioning API, exposing anchor points and visibility CSS variables so you can bind standard HTML elements like badges, tooltips, and cards directly to 3D coordinates.
This workflow guides designers through taking a layout from Figma into Framer and embedding interactive 3D assets from Spline. By exporting a public URL with hover and orbit controls from Spline, you can display reactive 3D graphics inside Framer using a standard Embed component. It allows teams to build visually rich, interactive landing pages without custom WebGL development.
This technique combines Spline, Sketchfab, and Webflow to build interactive 3D product showcases without writing Three.js code. Designers create a 3D model in Spline, upload it to Sketchfab to set up clickable camera annotations, and embed the interactive viewer via Webflow HTML blocks. It provides a simple way to highlight specific product features directly inside a web layout.
