InvSinWave 📅🅕🅝

Documentation

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

The InvSinWave node generates an inverse sine wave pattern, modifying the wave's amplitude based on the absolute value of the cosine function. It's designed for creating dynamic, wave-like animations or effects by adjusting parameters such as phase, amplitude, x translation, and y translation over a series of frames.

Input types

Required

• phase
  • Defines the period of the wave, affecting how many units it takes for the wave to complete one full cycle. A crucial parameter for controlling the wave's speed and spacing.
  • Comfy dtype: FLOAT
  • Python dtype: float
• amplitude
  • Determines the height of the wave's peaks. This parameter influences the wave's intensity and the range of its vertical movement.
  • Comfy dtype: FLOAT
  • Python dtype: float
• x_translation
  • Shifts the wave along the x-axis, allowing for horizontal positioning adjustments.
  • Comfy dtype: FLOAT
  • Python dtype: float
• y_translation
  • Adjusts the wave's vertical positioning, allowing for vertical positioning adjustments.
  • Comfy dtype: FLOAT
  • Python dtype: float
• current_frame
  • Specifies the current frame in the animation sequence, enabling the wave pattern to evolve over time.
  • Comfy dtype: INT
  • Python dtype: int

Output types

• float
  • Comfy dtype: FLOAT
  • Outputs the calculated wave value, useful for precise wave calculations.
  • Python dtype: float
• int
  • Comfy dtype: INT
  • Outputs the integer representation of the wave value, useful for scenarios requiring discrete values.
  • Python dtype: int

Usage tips

• Infra type: CPU
• Common nodes: unknown
