ComfyUI Node: Auto Pan Equilateral (mtb)

Auto Pan Equilateral (mtb):

The Auto Pan Equilateral (mtb) node is designed to generate a 360-degree panning video from an equilateral image. This node is particularly useful for creating immersive visual experiences by transforming a static equilateral image into a dynamic video that simulates a panoramic view. By adjusting various parameters such as field of view (FOV) and elevation, you can control the perspective and movement within the generated video. This node is ideal for AI artists looking to add a sense of depth and motion to their equilateral images, making their creations more engaging and visually appealing.

Auto Pan Equilateral (mtb) Input Parameters:

equilateral_image

This parameter accepts an equilateral image that serves as the source for generating the 360-degree panning video. The image should be in a format that the node can process, typically an image tensor.

fovX

This parameter sets the horizontal field of view (FOV) for the video. It controls how wide the view is horizontally. The default value is 45.0. Adjusting this value can change the perspective and the amount of the scene visible in the video.

fovY

This parameter sets the vertical field of view (FOV) for the video. It controls how wide the view is vertically. The default value is 45.0. Similar to fovX, changing this value affects the vertical perspective of the scene.

elevation

This parameter determines the elevation angle for the video, which affects the vertical position of the viewpoint. The default value is 0.5. Adjusting the elevation can simulate looking up or down within the scene.

frame_count

This parameter specifies the number of frames to generate for the video. The default value is 100. Increasing the frame count results in a smoother video but requires more processing time.

width

This parameter sets the width of the output video frames. The default value is 768. Adjusting the width can change the resolution and aspect ratio of the video.

height

This parameter sets the height of the output video frames. The default value is 512. Similar to width, changing the height affects the resolution and aspect ratio of the video.

floats_fovX

This optional parameter allows you to provide a list of float values to dynamically change the horizontal FOV for each frame. The list should match the frame count.

floats_fovY

This optional parameter allows you to provide a list of float values to dynamically change the vertical FOV for each frame. The list should match the frame count.

floats_elevation

This optional parameter allows you to provide a list of float values to dynamically change the elevation for each frame. The list should match the frame count.

Auto Pan Equilateral (mtb) Output Parameters:

image

This output parameter returns the generated 360-degree panning video as a sequence of image frames. Each frame is processed to reflect the specified FOV, elevation, and other parameters, resulting in a cohesive video that simulates a panoramic view.

Auto Pan Equilateral (mtb) Usage Tips:

• To create a smooth and visually appealing video, ensure that the frame_count is sufficiently high. A higher frame count results in smoother transitions between frames.
• Experiment with different fovX and fovY values to achieve the desired perspective. A wider FOV can capture more of the scene, while a narrower FOV can focus on specific details.
• Use the optional floats_fovX, floats_fovY, and floats_elevation parameters to add dynamic changes to the video. This can create more interesting and varied visual effects.

Auto Pan Equilateral (mtb) Common Errors and Solutions:

"You provided more than one image in the equilateral_image input, only the first will be used."

• Explanation: This warning indicates that multiple images were provided, but only the first image will be used for processing.
• Solution: Ensure that only one equilateral image is provided to avoid this warning.

"You provided less than the expected number of fovX, fovY, or elevation values."

• Explanation: This error occurs when the lists provided for floats_fovX, floats_fovY, or floats_elevation do not match the frame count.
• Solution: Verify that the length of each list matches the frame_count parameter to ensure proper processing.

"Processing interrupted."

• Explanation: This error indicates that the processing was interrupted, possibly due to an external factor or manual interruption.
• Solution: Ensure that the processing environment is stable and avoid manual interruptions during the node's execution.
