Effects

Efecto provides a variety of visual effects to transform your images, videos, and 3D content. Effects are applied in real-time using WebGL shaders.

Using Effects

Set the effect in your state object with a type and optional settings:

effect.json

{
  "effect": {
    "type": "ascii-standard",
    "settings": {
      "cellSize": 8,
      "colorMode": "color",
      "characters": " .:-=+*#%@"
    }
  }
}
