textmode.synth.js

A derivative work of hydra-synth by Olivia Jack, adapted for the textmode.js ecosystem, providing a visual synthesis system for procedural generation of characters, colors, and visual effects through method chaining.

Example

const t = textmode.create({
  width: window.innerWidth,
  height: window.innerHeight,
  plugins: [SynthPlugin]
});

const synth = noise(8)
  .rotate(0.2)
  .kaleid(5)
  .charColor(osc(6, 0.1, 1.2))
  .cellColor(osc(6, 0.1, 1.2).invert())
  .charMap('@#%*+=-:. ');

t.layers.base.synth(synth);

t.windowResized(() => {
  t.resizeCanvas(window.innerWidth, window.innerHeight);
});

Classes

Class	Description
SynthSource	A chainable synthesis source that accumulates transforms to be compiled into a shader.

Interfaces

Interface	Description
SynthContext	Context passed to dynamic parameter functions during rendering.
ModulatedArray	Extended array interface with modulation methods.

Type Aliases

Type Alias	Description
SynthParameterValue	Dynamic parameter value types supported by the synth system.
EasingFunction	Easing functions from https://gist.github.com/gre/1650294
DynamicErrorCallback	Callback signature for dynamic parameter evaluation errors. Live coding environments can use this to display errors without interrupting rendering.

Variables

Variable	Description
SynthPlugin	The textmode.synth.js plugin to install.

Functions

Function	Description
cellColor	Create a synth source with cell background color defined.
char	Create a character source from any color/pattern source.
charColor	Create a synth source with character foreground color defined.
gradient	Generate a rotating radial gradient.
noise	Generate Perlin noise patterns.
plasma	Generate plasma-like sine field patterns.
moire	Generate moire interference patterns.
osc	Generate oscillating patterns using sine waves.
paint	Create a synth source with both character and cell colors defined.
shape	Generate geometric shapes (polygons).
solid	Generate a solid grayscale color.
src	Sample a source for synth compositions.
voronoi	Generate voronoi patterns.
setGlobalErrorCallback	Set a global error callback for dynamic parameter evaluation errors.
