ASCII Animation

Render motion entirely with text characters. ASCII output is extremely lightweight, distinctive, and works in browsers (<pre>/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)).
