ComfyUI Node: 🔵 Spherize

🔵 Spherize:

The SpherizeNode is a powerful tool designed to apply a spherizing effect to images, creating a visual distortion that mimics the appearance of an image being wrapped around a sphere. This node is particularly useful for artists looking to add a dynamic and three-dimensional effect to their images, enhancing the visual interest and depth. By manipulating the image's pixels based on their distance from a specified center point, the node can create both convex and concave distortions, depending on the strength parameter. Additionally, the node offers a cylindrical mode, allowing for horizontal or vertical deformations, providing further creative flexibility. The SpherizeNode is an essential component for artists aiming to experiment with image deformation and achieve unique artistic effects.

🔵 Spherize Input Parameters:

image

The image parameter is the input image that you want to apply the spherizing effect to. It is the primary source material for the node's operations and should be provided in a compatible format.

strength

The strength parameter controls the intensity of the spherizing effect. A positive value results in a convex distortion, pushing the image outward, while a negative value creates a concave effect, pulling the image inward. The range for this parameter is from -2.0 to 2.0, with a default value of 0.5. Adjusting this parameter allows you to fine-tune the degree of distortion applied to the image.

radius

The radius parameter defines the effective radius of the spherizing effect, determining how far from the center the effect will extend. It ranges from 0.1 to 2.0, with a default value of 1.0. A larger radius will affect a greater portion of the image, while a smaller radius will confine the effect to a more localized area.

center_x

The center_x parameter specifies the horizontal position of the center point for the spherizing effect, expressed as a fraction of the image's width. It ranges from 0.0 to 1.0, with a default value of 0.5, placing the center at the middle of the image horizontally. Adjusting this parameter allows you to shift the focal point of the distortion left or right.

center_y

The center_y parameter determines the vertical position of the center point for the spherizing effect, expressed as a fraction of the image's height. It ranges from 0.0 to 1.0, with a default value of 0.5, centering the effect vertically. This parameter lets you move the focal point of the distortion up or down within the image.

mode

The mode parameter allows you to choose between two types of deformation: "spherize" and "cylindrical". The default mode is "spherize", which applies a spherical distortion to the image. The "cylindrical" mode, on the other hand, applies a horizontal or vertical deformation, depending on the image's aspect ratio, providing a different type of visual effect.

🔵 Spherize Output Parameters:

IMAGE

The output of the SpherizeNode is an IMAGE that has been transformed according to the specified parameters. This output image reflects the applied spherizing or cylindrical effect, showcasing the visual distortion and creative transformation achieved through the node's processing. The resulting image can be used for further artistic manipulation or as a final piece.

🔵 Spherize Usage Tips:

• Experiment with different strength values to achieve varying levels of distortion, from subtle to dramatic, to suit your artistic vision.
• Use the center_x and center_y parameters to shift the focal point of the effect, allowing you to create off-center distortions that can add dynamic interest to your compositions.
• Try the "cylindrical" mode for unique horizontal or vertical deformations that can complement the spherical effect, offering a broader range of creative possibilities.

🔵 Spherize Common Errors and Solutions:

Image format not supported

• Explanation: The input image is not in a compatible format for processing.
• Solution: Ensure that the image is in a supported format, such as a standard image tensor, before inputting it into the node.

Strength value out of range

• Explanation: The strength parameter is set outside the allowed range of -2.0 to 2.0.
• Solution: Adjust the strength value to be within the specified range to ensure proper functioning of the node.

Radius value out of range

• Explanation: The radius parameter is set outside the allowed range of 0.1 to 2.0.
• Solution: Modify the radius value to fall within the acceptable range to achieve the desired effect.

Center coordinates out of bounds

• Explanation: The center_x or center_y parameters are set outside the range of 0.0 to 1.0.
• Solution: Ensure that both center_x and center_y are within the specified range to correctly position the center of the effect.
