ComfyUI Node: KfSinusoidalWithFrequency

KfSinusoidalWithFrequency:

The KfSinusoidalWithFrequency node is designed to generate a sinusoidal curve based on a specified frequency, phase, and amplitude. This node is particularly useful for creating smooth, periodic variations in your AI art projects, allowing you to control the oscillation characteristics of the curve. By adjusting the frequency, you can determine how often the curve completes a full cycle within a given interval, while the phase allows you to shift the curve horizontally, and the amplitude controls the height of the oscillations. This node is essential for artists looking to incorporate rhythmic and wave-like patterns into their work, providing a high degree of control over the sinusoidal properties.

KfSinusoidalWithFrequency Input Parameters:

frequency

The frequency parameter determines how many cycles the sinusoidal curve completes in a unit interval. A higher frequency results in more cycles within the same interval, creating a more rapid oscillation. The default value is 1/12, and it can be adjusted in steps of 0.01. This parameter is crucial for defining the periodicity of the curve.

phase

The phase parameter shifts the sinusoidal curve horizontally along the x-axis. This allows you to start the curve at different points in its cycle. The default value is 0.0, and it can be adjusted in steps of 0.1308996939 (π/24). Adjusting the phase can help synchronize the curve with other elements in your project.

amplitude

The amplitude parameter controls the height of the oscillations in the sinusoidal curve. A higher amplitude results in taller peaks and deeper troughs, while a lower amplitude produces a flatter curve. The default value is 1, and it can be adjusted in steps of 0.01. This parameter is essential for scaling the intensity of the oscillations.

KfSinusoidalWithFrequency Output Parameters:

KEYFRAMED_CURVE

The KEYFRAMED_CURVE output is a keyframed representation of the generated sinusoidal curve. This output can be used in various applications where keyframed data is required, providing a smooth and continuous representation of the sinusoidal oscillations.

SINUSOIDAL_CURVE

The SINUSOIDAL_CURVE output is the sinusoidal curve itself, defined by the specified frequency, phase, and amplitude. This output is useful for directly applying the sinusoidal pattern to your AI art projects, allowing for precise control over the wave-like characteristics.

KfSinusoidalWithFrequency Usage Tips:

• Experiment with different frequency values to achieve the desired oscillation speed in your project.
• Use the phase parameter to align the sinusoidal curve with other elements in your composition.
• Adjust the amplitude to control the intensity of the oscillations, making the curve more or less pronounced as needed.
