ComfyUI Node: InvCosWave 📅🅕🅝

InvCosWave 📅🅕🅝:

The InvCosWave node is designed to generate an inverted cosine wave based on the provided parameters. This node is particularly useful for creating smooth, periodic variations in your AI art projects, allowing you to manipulate waveforms to achieve desired visual effects. By adjusting the phase, amplitude, translations, and current frame, you can control the shape and position of the wave, making it a versatile tool for dynamic and animated content creation. The main goal of this node is to provide a mathematical function that outputs a wave pattern, which can be used to influence various aspects of your artwork, such as color, position, or intensity.

InvCosWave 📅🅕🅝 Input Parameters:

phase

The phase parameter controls the period of the wave, determining how many frames it takes for the wave to complete one full cycle. A higher phase value results in a longer wave period, while a lower value shortens the period. The default value is 1.0, with a minimum of 0.0 and a maximum of 9999.0, adjustable in steps of 1.0.

amplitude

The amplitude parameter sets the height of the wave, affecting the maximum deviation from the wave's central axis. A higher amplitude results in a taller wave, while a lower amplitude produces a shorter wave. The default value is 0.5, with a minimum of 0.0 and a maximum of 9999.0, adjustable in steps of 0.1.

x_translation

The x_translation parameter shifts the wave horizontally along the x-axis. This translation allows you to move the wave left or right, effectively changing the starting point of the wave. The default value is 0.0, with a minimum of 0.0 and a maximum of 9999.0, adjustable in steps of 1.0.

y_translation

The y_translation parameter shifts the wave vertically along the y-axis. This translation allows you to move the wave up or down, effectively changing the baseline of the wave. The default value is 0.5, with a minimum of 0.0 and a maximum of 9999.0, adjustable in steps of 0.05.

current_frame

The current_frame parameter specifies the current frame of the animation, determining the position of the wave at a given point in time. This parameter is essential for creating animated effects, as it allows the wave to evolve over time. The default value is 1.0, with a minimum of 0.0 and a maximum of 9999.0, adjustable in steps of 1.0.

InvCosWave 📅🅕🅝 Output Parameters:

FLOAT

The FLOAT output represents the calculated value of the inverted cosine wave at the specified frame, taking into account the phase, amplitude, translations, and current frame. This value can be used to influence various aspects of your artwork, such as color intensity or positional adjustments.

INT

The INT output is the integer representation of the FLOAT output, providing a rounded value of the wave calculation. This can be useful for scenarios where an integer value is required, such as indexing or discrete adjustments.

InvCosWave 📅🅕🅝 Usage Tips:

• Experiment with different phase and amplitude values to create unique wave patterns that suit your artistic vision.
• Use x_translation and y_translation to fine-tune the position of the wave, ensuring it aligns perfectly with your design elements.
• Animate the current_frame parameter to create dynamic, evolving wave effects that add motion and interest to your artwork.

InvCosWave 📅🅕🅝 Common Errors and Solutions:

ValueError: math domain error

• Explanation: This error occurs when the input values result in an invalid mathematical operation, such as taking the square root of a negative number.
• Solution: Ensure that all input parameters are within their valid ranges and that the calculations do not produce invalid results.

TypeError: unsupported operand type(s)

• Explanation: This error occurs when the input parameters are of incorrect types, such as passing a string instead of a float.
• Solution: Verify that all input parameters are of the correct types as specified in the documentation.

OverflowError: numerical result out of range

• Explanation: This error occurs when the calculations produce a result that exceeds the numerical limits of the data type.
• Solution: Adjust the input parameters to ensure that the resulting values are within the acceptable range for floating-point numbers.
