KfSinusoidalGetAmplitude Description

Extract amplitude value from sinusoidal curve for AI art projects, enabling dynamic designs.

KfSinusoidalGetAmplitude:

The KfSinusoidalGetAmplitude node is designed to extract the amplitude value from a given sinusoidal curve. This node is particularly useful when you need to retrieve and utilize the amplitude of a sinusoidal wave in your AI art projects. The amplitude represents the peak value of the wave, which can be crucial for various artistic effects and animations. By using this node, you can easily access the amplitude parameter, allowing for more dynamic and responsive designs.

KfSinusoidalGetAmplitude Input Parameters:

curve

This parameter requires a sinusoidal curve input, which is specified as SINUSOIDAL_CURVE. The curve input is mandatory and must be provided for the node to function correctly. The sinusoidal curve contains various properties, including amplitude, wavelength, and phase, but this node specifically focuses on extracting the amplitude value.

KfSinusoidalGetAmplitude Output Parameters:

FLOAT

The output of this node is a single floating-point number representing the amplitude of the provided sinusoidal curve. This value indicates the maximum extent of the wave from its equilibrium position, which can be used to control various aspects of your AI art, such as scaling, intensity, or other amplitude-dependent effects.

KfSinusoidalGetAmplitude Usage Tips:

Ensure that the input curve is a valid sinusoidal curve to avoid errors and obtain accurate amplitude values.
Use the extracted amplitude value to modulate other parameters in your project, such as the size or intensity of visual elements, to create more dynamic and engaging effects.
Combine this node with other sinusoidal nodes to create complex animations and transitions based on the amplitude of the wave.

KfSinusoidalGetAmplitude Common Errors and Solutions:

Invalid input type for `curve`

Explanation: This error occurs when the input provided is not a valid SINUSOIDAL_CURVE.
Solution: Ensure that the input to the curve parameter is a properly defined sinusoidal curve. Verify the source of the curve and its properties.

Missing required input `curve`

Explanation: This error occurs when the curve input is not provided.
Solution: Make sure to connect a valid sinusoidal curve to the curve input parameter before executing the node.
