ComfyUI Node: STEREOGRAM (JOV) 📻

STEREOGRAM (JOV) 📻:

The Stereogram node is designed to create stereograms, which are 3D images generated from 2D input. This node allows you to control various parameters such as tile divisions, noise, gamma, and shift to customize the appearance of the stereogram. By adjusting these settings, you can influence the depth and visual effects of the resulting 3D image. This node is particularly useful for AI artists looking to add a unique 3D perspective to their 2D artworks, making it a powerful tool for creating visually engaging and immersive images.

STEREOGRAM (JOV) 📻 Input Parameters:

PIXEL

This optional parameter accepts any type of image input. It serves as the base image from which the stereogram will be generated. If not provided, a default solid channel image will be used.

DEPTH

This optional parameter also accepts any type of image input and is used to define the depth map for the stereogram. The depth map influences the 3D effect by determining how far each part of the image appears from the viewer. If not provided, a default solid channel image will be used.

TILE

This integer parameter sets the number of tile divisions in the stereogram. It controls the granularity of the 3D effect. The default value is 8, with a minimum of 1. Increasing the number of tiles can make the 3D effect more detailed.

NOISE

This float parameter adds noise to the stereogram, which can help in creating a more natural and less uniform 3D effect. The default value is 0.33, with a range from 0 to 1 and a step of 0.01. Higher values increase the amount of noise.

GAMMA

This float parameter adjusts the gamma correction of the stereogram, affecting the brightness and contrast of the 3D effect. The default value is 0.33, with a range from 0 to 1 and a step of 0.01. Adjusting gamma can help in fine-tuning the visual quality of the stereogram.

SHIFT

This float parameter controls the horizontal shift of the stereogram, which influences the perceived depth. The default value is 1.0, with a range from -1 to 1 and a step of 0.01. Positive values shift the image to the right, while negative values shift it to the left.

INVERT

This boolean parameter, when set to true, inverts the depth map, reversing the depth effect. The default value is False. Inverting the depth can create interesting visual effects by flipping the 3D perspective.

STEREOGRAM (JOV) 📻 Output Parameters:

IMAGE

The output is a tensor representing the generated stereogram image. This image combines the base image and the depth map to create a 3D effect that can be viewed using stereoscopic techniques.

STEREOGRAM (JOV) 📻 Usage Tips:

• Experiment with different tile division values to find the optimal balance between detail and processing time.
• Use the noise parameter to add a natural texture to the stereogram, making the 3D effect more convincing.
• Adjust the gamma setting to enhance the brightness and contrast, improving the overall visual quality of the stereogram.
• Try inverting the depth map to explore unique and creative 3D effects.

STEREOGRAM (JOV) 📻 Common Errors and Solutions:

"Invalid image input for PIXEL or DEPTH"

• Explanation: This error occurs when the provided image input is not in a supported format.
• Solution: Ensure that the input images for PIXEL and DEPTH are in a compatible format, such as PNG or JPEG.

"Tile division value out of range"

• Explanation: This error occurs when the TILE parameter is set to a value outside the allowed range.
• Solution: Set the TILE parameter to a value between 1 and the maximum allowed value, which is 8.

"Noise, gamma, or shift value out of range"

• Explanation: This error occurs when the NOISE, GAMMA, or SHIFT parameters are set to values outside their respective ranges.
• Solution: Ensure that the NOISE and GAMMA parameters are set between 0 and 1, and the SHIFT parameter is set between -1 and 1.
