AbsCosWave 📅🅕🅝

Documentation

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

The AbsCosWave node generates a wave pattern based on the absolute value of a cosine function, modulated by parameters such as phase, amplitude, x_translation, and max_value. It's designed to create dynamic, visually interesting waveforms for various applications.

Input types

Required

• phase
  • The phase parameter controls the periodicity of the wave, affecting how frequently the wave pattern repeats over a given interval.
  • Comfy dtype: FLOAT
  • Python dtype: float
• amplitude
  • Amplitude determines the height of the wave peaks, influencing the overall intensity of the wave pattern.
  • Comfy dtype: FLOAT
  • Python dtype: float
• x_translation
  • X_translation shifts the wave pattern along the horizontal axis, allowing for adjustments in the wave's starting position.
  • Comfy dtype: FLOAT
  • Python dtype: float
• max_value
  • Max_value sets the upper limit for the wave's value, capping the peak height and affecting the wave's amplitude.
  • Comfy dtype: FLOAT
  • Python dtype: float
• current_frame
  • Current_frame represents a specific point in time or sequence, used to calculate the wave's position and shape at that moment.
  • Comfy dtype: INT
  • Python dtype: int

Output types

• float
  • Comfy dtype: FLOAT
  • The first element of the output tuple, representing the calculated wave value in its precise form.
  • Python dtype: float
• int
  • Comfy dtype: INT
  • The second element of the output tuple, providing an integer approximation of the wave's current state.
  • Python dtype: int

Usage tips

• Infra type: CPU
• Common nodes: unknown
