Post-Processing

Wave

Wave applies sinusoidal displacement to the image, creating rippling, wavy distortions. This effect can simulate water reflections, heat haze, or psychedelic visuals.

Example Configuration

wave.json

{
  "effect": {
    "postProcesses": [
      {
        "id": "pp_wave",
        "type": "wave",
        "enabled": true,
        "settings": {
          "amplitude": 0.1,
          "frequency": 5,
          "speed": 1
        }
      }
    ]
  }
}

Settings

Property	Type	Range	Default	Description
`amplitude`	number	0-1	0.1	Wave height/intensity
`frequency`	number	1-20	5	Number of waves across the image
`speed`	number	0-5	1	Animation speed (0 = static)

Suggested Presets

Style	Settings
Subtle Ripple	amplitude: 0.02, frequency: 8, speed: 0.5

Tips

Keep amplitude low (0.02-0.1) for realistic effects
Higher frequency creates tighter, more rapid waves
Combine with chromatic aberration for underwater look
Set speed to 0 for static wavy distortion
Works well for dreamy, surreal aesthetics
