ComfyUI Node: Circle Creator

Circle Creator:

The CircleCreator node is designed to help you create custom circles for your AI art projects. This node allows you to define the position and size of a circle, and even create a "dount" (donut) circle with a customizable inner circle diameter. While it may have some limitations, it offers a fun and creative way to generate circular shapes that can be used in conjunction with other nodes like Create Circle Mask. This node is particularly useful for adding geometric elements to your artwork, providing a straightforward method to generate circles with specific attributes.

Circle Creator Input Parameters:

c_X, c_Y

These parameters define the top-left position of your circle, not the center. The values you provide here will determine where the circle starts on the canvas. Adjusting these values allows you to position the circle precisely where you want it in your artwork.

diameter

This parameter sets the diameter of the circle. The diameter determines the overall size of the circle, and you can adjust it to make the circle larger or smaller depending on your needs.

dount, dount_size

The dount parameter enables the creation of a donut-shaped circle. When this is enabled, the dount_size parameter controls the percentage of the inner circle's diameter relative to the outer circle. This allows you to create circles with a hollow center, adding more complexity and variety to your designs.

Circle Creator Output Parameters:

opt_circle

This output parameter is an override node that connects to the Create Circle Mask node's opt_circle input. It provides the necessary data to generate the circle mask based on the parameters you have set, allowing for seamless integration with other nodes in your workflow.

Circle Creator Usage Tips:

• Experiment with different c_X and c_Y values to position your circles precisely where you want them on the canvas.
• Use the diameter parameter to create circles of varying sizes, adding depth and interest to your artwork.
• Enable the dount parameter and adjust the dount_size to create unique donut-shaped circles that can serve as interesting design elements.

Circle Creator Common Errors and Solutions:

Mira: [Create Circle Mask] -> Connect at least ONE opt node.

• Explanation: This error occurs when no opt_circle node is connected to the Create Circle Mask node.
• Solution: Ensure that you have connected the opt_circle output from the CircleCreator node to the Create Circle Mask node's opt_circle input. This connection is necessary for the circle mask to be generated correctly.
