modulate

.modulate( texture, amount )

• texture
  • color :: see color vec4

• amount :: float (default 0.1)

Modulate texture. More about modulation at: https://lumen-app.com/guide/modulation/

Example

voronoi()
  .color(0.9,0.25,0.15)
  .rotate(({time})=>(time%360)/2)
  .modulate(osc(25,0.1,0.5)
            .kaleid(50)
            .scale(({time})=>Math.sin(time*1)*0.5+1)
            .modulate(noise(0.6,0.5)),
            0.5)
  .out(o0)

modulateHue

.modulateHue( color, amount )

• texture
  • color :: see color vec4
