AbsSinWave 📅🅕🅝

Documentation

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

The AbsSinWave node generates a sine wave where the sine function's output is modified by the absolute value, creating a unique wave pattern. This transformation is applied to model wave-like behaviors with a distinctive mathematical alteration.

Input types

Required

phase
- The 'phase' parameter controls the period of the sine wave, affecting how quickly the wave cycles through its pattern.
- Comfy dtype: FLOAT
- Python dtype: float
amplitude
- The 'amplitude' parameter determines the height of the wave peaks, influencing the wave's overall intensity.
- Comfy dtype: FLOAT
- Python dtype: float
x_translation
- The 'x_translation' parameter shifts the wave along the x-axis, allowing for adjustments in the wave's starting position.
- Comfy dtype: FLOAT
- Python dtype: float
max_value
- The 'max_value' parameter sets the maximum value the wave can reach, influencing the wave's peak.
- Comfy dtype: FLOAT
- Python dtype: float
current_frame
- The 'current_frame' parameter specifies the current point in time or frame 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 output is the calculated wave value as a float, reflecting the wave's current state.
- Python dtype: float
int
- Comfy dtype: INT
- The second output is the integer representation of the calculated wave value, providing a discrete measure of the wave's state.
- Python dtype: int
