TriangleWave 📅🅕🅝

Documentation

  • Class name: TriangleWave
  • Category: FizzNodes 📅🅕🅝/WaveNodes
  • Output node: False

The TriangleWave node generates a triangular wave pattern based on the provided parameters. It manipulates the wave's phase, amplitude, and translations along the x and y axes, as well as the current frame to produce a unique wave output.

Input types

Required

  • phase
    • The 'phase' parameter determines the period of the triangular wave, affecting how frequently the wave pattern repeats over a given interval.
    • Comfy dtype: FLOAT
    • Python dtype: float
  • amplitude
    • The 'amplitude' parameter specifies the height of the triangular wave, influencing the peak values the wave can reach.
    • Comfy dtype: FLOAT
    • Python dtype: float
  • x_translation
    • The 'x_translation' parameter shifts the wave along the x-axis, allowing for horizontal adjustment of the wave's position.
    • Comfy dtype: FLOAT
    • Python dtype: float
  • y_translation
    • The 'y_translation' parameter shifts the wave along the y-axis, providing vertical adjustment to the base level of the wave.
    • Comfy dtype: FLOAT
    • Python dtype: float
  • current_frame
    • The 'current_frame' parameter indicates the specific point in time for which the wave's value is being calculated, playing a crucial role in the wave's progression.
    • Comfy dtype: INT
    • Python dtype: int

Output types

  • float
    • Comfy dtype: FLOAT
    • The first element of the output tuple, representing the calculated wave value as a float.
    • Python dtype: float
  • int
    • Comfy dtype: INT
    • The second element of the output tuple, which is the integer representation of the calculated wave value.
    • Python dtype: int

Usage tips

  • Infra type: CPU
  • Common nodes: unknown
