ComfyUI Node: KfSinusoidalAdjustWavelength

KfSinusoidalAdjustWavelength:

The KfSinusoidalAdjustWavelength node is designed to modify the wavelength of an existing sinusoidal curve. This adjustment allows you to fine-tune the periodicity of the curve, effectively changing the distance between successive peaks or troughs. By altering the wavelength, you can control the frequency of oscillations in your sinusoidal data, which can be particularly useful in various AI art applications where precise control over wave patterns is required. This node ensures that the adjustments are seamlessly integrated into the existing curve, maintaining the original phase and amplitude while only modifying the wavelength.

KfSinusoidalAdjustWavelength Input Parameters:

curve

This parameter expects a sinusoidal curve (SINUSOIDAL_CURVE) as input. The curve represents the initial wave pattern that you want to adjust. The node will use this curve's current wavelength, phase, and amplitude as the basis for the adjustment. This input is required and must be provided for the node to function.

adjustment

The adjustment parameter is a floating-point value (FLOAT) that specifies the amount by which the wavelength of the input curve should be adjusted. The default value is 0.0, and it can be incremented in steps of 0.5. Positive values will increase the wavelength, making the wave longer, while negative values will decrease the wavelength, making the wave shorter. This parameter allows for precise control over the modification of the curve's periodicity.

KfSinusoidalAdjustWavelength Output Parameters:

KEYFRAMED_CURVE

This output provides the adjusted sinusoidal curve as a keyframed curve. The keyframed curve retains the original phase and amplitude but has an updated wavelength based on the specified adjustment. This output can be used in further processing or visualization steps where keyframed data is required.

SINUSOIDAL_CURVE

This output provides the adjusted sinusoidal curve in its original sinusoidal form. Similar to the keyframed curve, it retains the original phase and amplitude but with the updated wavelength. This output is useful for applications that specifically require sinusoidal data.

KfSinusoidalAdjustWavelength Usage Tips:

• To achieve subtle changes in the wave pattern, use small adjustment values. This allows for fine-tuning without drastically altering the curve.
• Combine this node with other sinusoidal adjustment nodes, such as KfSinusoidalAdjustPhase or KfSinusoidalAdjustAmplitude, to create complex waveforms with precise control over multiple parameters.
• Use the KEYFRAMED_CURVE output for applications that require interpolation between keyframes, and the SINUSOIDAL_CURVE output for direct sinusoidal data manipulation.

KfSinusoidalAdjustWavelength Common Errors and Solutions:

"Input curve is not a valid SINUSOIDAL_CURVE"

• Explanation: This error occurs when the provided input curve does not match the expected SINUSOIDAL_CURVE type.
• Solution: Ensure that the input curve is correctly formatted as a SINUSOIDAL_CURVE. Verify that the curve has the necessary properties such as wavelength, phase, and amplitude.

"Adjustment value is out of range"

• Explanation: This error occurs when the adjustment value is outside the acceptable range for the node.
• Solution: Check the adjustment value and ensure it is within a reasonable range. The default step size is 0.5, so adjustments should be made in increments that make sense for the specific application.

"Curve adjustment resulted in invalid wavelength"

• Explanation: This error occurs if the adjustment results in a wavelength that is not physically meaningful (e.g., zero or negative wavelength).
• Solution: Adjust the value to ensure that the resulting wavelength remains positive and within a practical range for sinusoidal curves.
