Glossary of immersive website prompts
Answer in brief
The terms that turn up in prompts for 3D, WebGL and scroll-driven sites, each defined in a sentence or two.
- Immersive website
- A site that reads as a space and not a page: it has depth, one continuous scene, and it responds to scroll or the pointer. See what makes a website immersive.
- WebGL
- The browser's interface for drawing with the graphics card on a canvas element. It is what makes real-time 3D and full-screen shaders possible on a web page.
- three.js
- A widely used JavaScript library that sits on top of WebGL and provides scenes, cameras, lights, materials and model loaders. Name it in a prompt when there are 3D objects; a single flat shader does not need it.
- Shader
- A small program that runs on the graphics card. A vertex shader places points; a fragment shader decides the colour of each pixel. See WebGL hero prompts.
- Pixel ratio
- How many device pixels make up one CSS pixel. High-density screens have a ratio of 2 or more, which multiplies the pixels a canvas must fill. Capping it is the first performance control.
- Draw call
- One instruction to the graphics card to draw one object. Each has overhead, so fewer is better. See the performance budget.
- Instancing
- Drawing many copies of the same shape in a single draw call, each with its own position and colour. The standard way to draw hundreds of repeated objects cheaply.
- GLB
- The single-file binary form of glTF, the usual format for 3D models on the web. A GLB with separately named parts can be taken apart in code. See 3D product website prompts.
- Scroll progress
- How far the visitor has scrolled through a pinned stretch of page, as a number from 0 to 1. Scroll moments are written as ranges of it.
- Pinning
- Holding an element fixed on screen while the page scrolls beneath it, for a set distance. See scroll-driven animation in prompts.
- Point cloud
- A shape made of many separate points with no surface between them. See particle website prompts.
- Fallback
- What a visitor sees when the full scene cannot or should not run: on a slow device, without WebGL, or with reduced motion switched on. Usually a set of still images with the same copy.
Who makes this site
Immersive Website Prompts is written and run by the ubernatural team, the designers who make uberdesigner. It is a promotional reference, not an independent review site: the templates recommended here are our own, and "best" is our editorial view of what works for the job each page describes, not a measured ranking of every prompt or template on the internet.
