ComfyUI Node: 🌊 Ripple

🌊 Ripple:

The RippleNode is a powerful tool designed to apply a ripple effect to images, creating a dynamic and visually engaging transformation. This node is part of the deformation category in image effects, allowing you to simulate the appearance of waves or ripples emanating from a central point on an image. By manipulating parameters such as amplitude, frequency, and wave type, you can control the intensity and pattern of the ripples, making it a versatile tool for adding artistic flair or simulating natural water effects. The node's ability to adjust the center of the ripple, phase, and decay further enhances its flexibility, enabling you to create a wide range of ripple effects tailored to your creative vision.

🌊 Ripple Input Parameters:

image

This parameter represents the input image to which the ripple effect will be applied. It is the starting point for the transformation and should be provided in a compatible format for processing.

amplitude

The amplitude parameter controls the height of the ripples. A higher amplitude results in more pronounced ripples, while a lower amplitude creates subtler effects. The default value is 20.0, with a range from 0.0 to 100.0, allowing for fine-tuning of the ripple intensity.

frequency

Frequency determines the number of ripples within a given area. A higher frequency results in more closely spaced ripples, while a lower frequency spreads them out. The default value is 0.02, with a range from 0.001 to 0.1, providing flexibility in the ripple pattern.

wave_type

This parameter specifies the type of wave used to generate the ripples. Options include "sine," "cosine," and "both," with "sine" as the default. Each wave type offers a distinct ripple pattern, allowing for creative variations in the effect.

center_x

Center_x sets the horizontal position of the ripple's origin, with a default value of 0.5, representing the center of the image. The range is from 0.0 to 1.0, enabling you to shift the ripple's starting point horizontally.

center_y

Similar to center_x, center_y determines the vertical position of the ripple's origin. It also defaults to 0.5, with a range from 0.0 to 1.0, allowing for vertical adjustments of the ripple's center.

phase

Phase adjusts the starting point of the wave cycle, influencing the initial appearance of the ripples. The default is 0.0, with a range from 0.0 to 6.28, providing control over the wave's phase shift.

decay

Decay controls the reduction in ripple intensity as the distance from the center increases. A higher decay value results in faster attenuation of the ripples. The default is 0.0, with a range from 0.0 to 1.0, allowing for gradual or rapid decay effects.

🌊 Ripple Output Parameters:

IMAGE

The output is an image with the applied ripple effect. This transformed image reflects the adjustments made through the input parameters, showcasing the dynamic ripple pattern superimposed on the original image. The output is suitable for further processing or direct use in creative projects.

🌊 Ripple Usage Tips:

• Experiment with different combinations of amplitude and frequency to achieve the desired ripple intensity and spacing for your image.
• Use the center_x and center_y parameters to position the ripple effect strategically, enhancing specific areas of your image.
• Adjust the decay parameter to create a natural fading effect, which can add depth and realism to the ripple pattern.

🌊 Ripple Common Errors and Solutions:

Image format not supported

• Explanation: The input image is not in a compatible format for processing.
• Solution: Ensure the image is in a supported format, such as a standard image tensor, before applying the ripple effect.

Invalid parameter value

• Explanation: One or more input parameters are set outside their allowable range.
• Solution: Double-check the parameter values to ensure they fall within the specified ranges and adjust them accordingly.
