ComfyUI Node: KfSinusoidalAdjustFrequency

KfSinusoidalAdjustFrequency:

The KfSinusoidalAdjustFrequency node is designed to modify the frequency of an existing sinusoidal curve. This node allows you to fine-tune the frequency of a sinusoidal waveform by applying an adjustment value, which can be particularly useful in animation and procedural generation tasks where precise control over the waveform's characteristics is required. By adjusting the frequency, you can change how often the waveform oscillates over a given period, thereby affecting the overall behavior and appearance of the curve. This node is essential for creating dynamic and responsive animations that require smooth and continuous adjustments to the sinusoidal parameters.

KfSinusoidalAdjustFrequency Input Parameters:

curve

The curve parameter expects a sinusoidal curve input (SINUSOIDAL_CURVE). This input is mandatory and must be provided for the node to function. The curve represents the initial sinusoidal waveform that you wish to adjust. The node will use the properties of this curve, such as its wavelength, phase, and amplitude, to apply the frequency adjustment.

adjustment

The adjustment parameter is a floating-point value (FLOAT) that specifies the amount by which to adjust the frequency of the input curve. The default value is 0, and it can be adjusted in steps of 0.01. This parameter directly influences the frequency of the sinusoidal curve, allowing you to increase or decrease the number of oscillations per unit time. A positive adjustment value will increase the frequency, while a negative value will decrease it.

KfSinusoidalAdjustFrequency Output Parameters:

KEYFRAMED_CURVE

The KEYFRAMED_CURVE output is a keyframed version of the adjusted sinusoidal curve. This output can be used in animation systems where keyframing is required to interpolate between different states over time. It retains the adjusted frequency and other properties of the original curve.

SINUSOIDAL_CURVE

The SINUSOIDAL_CURVE output is the adjusted sinusoidal curve with the new frequency applied. This output can be used directly in systems that utilize sinusoidal curves for various purposes, such as procedural generation, signal processing, or visual effects. It reflects the changes made by the adjustment parameter.

KfSinusoidalAdjustFrequency Usage Tips:

• To achieve a smooth transition in animations, use small adjustment values and gradually increase or decrease the frequency.
• Combine this node with other sinusoidal adjustment nodes to create complex waveforms with varying properties.
• Use the KEYFRAMED_CURVE output for applications that require interpolation between different states, such as character animations or dynamic effects.

KfSinusoidalAdjustFrequency Common Errors and Solutions:

"Invalid curve input"

• Explanation: The curve parameter is not provided or is not a valid SINUSOIDAL_CURVE.
• Solution: Ensure that you provide a valid sinusoidal curve as input to the curve parameter.

"Adjustment value out of range"

• Explanation: The adjustment parameter value is too large or too small, causing the frequency to become invalid.
• Solution: Use smaller adjustment values and ensure that the resulting frequency remains within a reasonable range.
