ComfyUI Node: Image Displacement Warp

Image Displacement Warp:

The Image Displacement Warp node is designed to creatively distort an image by using a displacement map and an amplitude value. This node allows you to achieve unique visual effects by shifting pixels in the original image based on the intensity values in the displacement map. The primary goal of this node is to provide a way to manipulate images in a controlled yet artistic manner, making it a valuable tool for AI artists looking to add dynamic and intriguing distortions to their work. By leveraging the displacement map, you can create effects that range from subtle warps to dramatic transformations, enhancing the visual appeal and complexity of your images.

Image Displacement Warp Input Parameters:

image

This parameter represents the original image that you want to apply the displacement warp to. The image should be in RGB format to ensure accurate color representation during the displacement process.

displacement_map

The displacement map is a grayscale image that dictates how the original image will be distorted. The intensity values in the displacement map determine the amount and direction of pixel shifts in the original image. The map should be in grayscale (L mode) to function correctly.

amplitude

The amplitude parameter controls the strength of the displacement effect. It is a float value that scales the displacement amount derived from the displacement map. Higher amplitude values result in more pronounced distortions, while lower values produce subtler effects. The default value is not specified, but it should be chosen based on the desired intensity of the warp effect.

Image Displacement Warp Output Parameters:

result

The result parameter is the output image that has been distorted based on the displacement map and amplitude value. This image retains the original dimensions and color format (RGB) but exhibits the visual distortions applied through the displacement process.

Image Displacement Warp Usage Tips:

• Experiment with different displacement maps to achieve a variety of distortion effects. Simple gradient maps can create smooth warps, while more complex maps can produce intricate and chaotic distortions.
• Adjust the amplitude parameter to fine-tune the intensity of the displacement effect. Start with lower values for subtle changes and gradually increase the amplitude to explore more dramatic transformations.
• Use high-resolution images and displacement maps to ensure that the details of the distortion are preserved and appear smooth.

Image Displacement Warp Common Errors and Solutions:

Image and displacement map must be the same size

• Explanation: This error occurs when the dimensions of the original image and the displacement map do not match.
• Solution: Ensure that both the image and the displacement map have the same width and height before applying the displacement warp.

Invalid image format

• Explanation: This error is raised if the input image is not in RGB format or the displacement map is not in grayscale (L mode).
• Solution: Convert the original image to RGB format and the displacement map to grayscale (L mode) before using them as inputs.

Amplitude value out of range

• Explanation: This error occurs if the amplitude value is set to an invalid range that the node cannot process.
• Solution: Ensure that the amplitude value is a positive float and within a reasonable range to avoid excessive distortions that could lead to unexpected results.
