ASCII Animation Render motion entirely with text characters. ASCII output is extremely lightweight, distinctive, and works in browsers (
/canvas), terminals (ANSI), and over any 3D scene (Three.js
AsciiEffect
).
When to use
Build terminal/CLI intros, loaders, banners, or a retro/hacker aesthetic.
Convert an image, video frame, or 3D scene into animated ASCII.
Add an ASCII post-effect over an existing canvas/WebGL render.
Create generative text fields (plasma, sine waves, noise, tunnels).
Core concept: the brightness ramp
Map luminance (0..1) to a character whose ink density matches. Order characters dark-to-light. Pick the index with
Math.round(lum * (ramp.length - 1))
.
