v0.40

A field that uses a periodic wave.

If there is an input, that rop is used to get the coordinate that is fed into the wave function. Without an input, the Axis is used to run the wave function on the position along the selected axis.

Wave

The type of wave.

  • Additive Square (8):
Axis

Axis used for the wave function phase. If there is a coordinate field, this controls which part of the returned value is used. Otherwise it controls which part of the position in used.

Period

The length of a single cycle of the wave.
Phase

Offset of the wave along the axis / coordinates.
Amplitude

The height of the wave, which scales the range of output values. If this is set to 3 (and Offset is 0), a ramp wave will produce values from 0 to 3.

 Runtime Baked
Offset

Adds to the values produced by the wave. If this is set to 0.5 (and Amplitude is set to 1), a ramp wave will produce values from 0.5 to 1.5.

Inputs

  • Coordinate Field: (optional) If attached, the wave will use this to determine the numbers that it passes to the wave function (instead of using the position along the chosen `Axis`).
    • Coordinate Types: float vec2 vec3 vec4
    • Context Types: Context MaterialContext CameraContext LightContext RayContext ParticleContext VertexContext PixelContext
    • Return Types: float vec4
  • Period Field: (optional) If attached, the wave will use this field to multiply the `Period` parameter, which can be used for frequency modulation.
