ComfyUI Node: CosWave 📅🅕🅝

CosWave 📅🅕🅝:

The CosWave node is designed to generate a cosine wave pattern, which can be used in various creative and artistic applications. This node allows you to manipulate the wave's phase, amplitude, and translations along the x and y axes, as well as the current frame, to create dynamic and visually appealing effects. By adjusting these parameters, you can control the shape and behavior of the cosine wave, making it a versatile tool for adding rhythmic and oscillatory elements to your projects. The primary goal of the CosWave node is to provide a simple yet powerful way to incorporate cosine waveforms into your artistic creations, enhancing the visual complexity and movement within your work.

CosWave 📅🅕🅝 Input Parameters:

phase

The phase parameter controls the period of the cosine 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 minimum value is 0.0, the maximum is 9999.0, and the default is 1.0.

amplitude

The amplitude parameter sets the height of the cosine wave, affecting the wave's peak and trough values. A higher amplitude results in a taller wave, while a lower amplitude produces a shorter wave. The minimum value is 0.0, the maximum is 9999.0, and the default is 0.5.

x_translation

The x_translation parameter shifts the cosine 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 minimum value is 0.0, the maximum is 9999.0, and the default is 0.0.

y_translation

The y_translation parameter shifts the cosine wave vertically along the y-axis. This translation allows you to move the wave up or down, adjusting the baseline of the wave. The minimum value is 0.0, the maximum is 9999.0, and the default is 0.5.

current_frame

The current_frame parameter specifies the current frame number in the animation or sequence. This parameter is used to calculate the wave's position at a given point in time, allowing for dynamic and time-based wave generation. The minimum value is 0.0, the maximum is 9999.0, and the default is 1.0.

CosWave 📅🅕🅝 Output Parameters:

FLOAT

The FLOAT output represents the calculated value of the cosine wave at the specified frame, taking into account the phase, amplitude, and translations. This value can be used to drive other parameters or visual elements in your project, providing a smooth and continuous wave pattern.

INT

The INT output is the integer representation of the FLOAT output. This value can be useful for applications that require discrete or quantized values, such as triggering events or controlling step-based animations.

CosWave 📅🅕🅝 Usage Tips:

• Experiment with different phase values to create waves with varying frequencies and periods, adding diversity to your animations.
• Adjust the amplitude to control the intensity of the wave effect, making it more or less pronounced depending on your artistic needs.
• Use x_translation and y_translation to position the wave precisely within your composition, ensuring it aligns with other visual elements.
• Animate the current_frame parameter to create dynamic and evolving wave patterns that change over time, adding movement and interest to your work.

CosWave 📅🅕🅝 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 phase value is not zero to avoid division by zero errors.

"TypeError: unsupported operand type(s)"

• Explanation: This error happens 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, and convert any incorrect types before passing them to the node.

"OverflowError: numerical result out of range"

• Explanation: This error occurs when the input values are too large, causing the mathematical operations to exceed the numerical limits.
• Solution: Check that all input parameters are within the specified maximum values and reduce them if necessary to prevent overflow errors.
