SawtoothWave 📅🅕🅝

Documentation

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

The SawtoothWave node is designed for generating and manipulating sawtooth waveforms, which are characterized by a linear rise and sharp fall. This node facilitates the creation of these periodic functions, allowing for their use in various applications that require such wave patterns.

Input types

Required

• phase
  • Defines the period of the sawtooth wave, affecting its repetition rate.

• step_increment
  • Determines the incremental steps in the sawtooth wave's progression.
  • Comfy dtype: FLOAT
  • Python dtype: float
• x_translation
  • Adjusts the horizontal positioning of the sawtooth wave.
  • Comfy dtype: FLOAT
  • Python dtype: float
• start_value
  • Sets the starting value of the sawtooth wave, establishing its initial position.
  • Comfy dtype: FLOAT
  • Python dtype: float
• current_frame
  • Indicates the current point in time for the wave's calculation, crucial for its dynamic progression.
