ComfyUI Node: SSsnap Calc 🪛

SSsnap Calc 🪛:

The CalcScaledPoseDiff node is designed to compute the difference between two sets of pose keypoints, specifically an adjusted pose and a scaled pose. This node is particularly useful in scenarios where you need to analyze the variations or transformations applied to a pose, such as in animation or motion capture applications. By calculating the difference, it allows you to understand how much a pose has been altered, which can be crucial for tasks like pose correction, animation blending, or even in AI-driven art where pose dynamics are essential. The node processes the input poses and outputs the difference in a structured format, making it easier to integrate into larger workflows that require pose manipulation or analysis.

SSsnap Calc 🪛 Input Parameters:

adjusted_pose

The adjusted_pose parameter represents the pose keypoints that have been modified or adjusted from their original state. This input is crucial as it serves as one of the two reference points for calculating the difference. The parameter expects data in the form of POSE_KEYPOINT, which typically includes a list of 2D coordinates representing various body parts. There are no specific minimum, maximum, or default values, but the data should be structured correctly to ensure accurate calculations.

scaled_pose

The scaled_pose parameter is the second set of pose keypoints, which have been scaled or transformed in some manner. Like the adjusted_pose, this input is also in the POSE_KEYPOINT format and is essential for determining the difference between the two poses. The scaled pose provides the second reference point, and the node calculates how much each keypoint has shifted or changed in relation to the adjusted pose. Properly formatted data is necessary for the node to function correctly.

SSsnap Calc 🪛 Output Parameters:

scaled_pose_diff

The scaled_pose_diff output parameter provides the calculated difference between the adjusted_pose and the scaled_pose. This output is in the form of POSE_KEYPOINT, containing a list of differences for each keypoint. The significance of this output lies in its ability to quantify the changes between the two poses, which can be used for further processing or analysis in applications that require precise pose adjustments or comparisons.

SSsnap Calc 🪛 Usage Tips:

• Ensure that both adjusted_pose and scaled_pose inputs are correctly formatted and contain the same number of keypoints to avoid errors and ensure accurate difference calculations.
• Use the scaled_pose_diff output to fine-tune animations or to create smooth transitions between poses by applying the calculated differences incrementally.

SSsnap Calc 🪛 Common Errors and Solutions:

Pose shapes mismatch.

• Explanation: This error occurs when the shapes of the adjusted_pose and scaled_pose do not match, meaning they have a different number of keypoints or are not structured identically.
• Solution: Verify that both input poses are correctly formatted and contain the same number of keypoints. Ensure that the data structure is consistent for both inputs before processing.

Input pose data is invalid or malformed.

• Explanation: This error suggests that the input data for either adjusted_pose or scaled_pose is not in the expected format or is missing required information.
• Solution: Check the input data to ensure it is correctly structured as a list of keypoints with the necessary fields. Correct any discrepancies in the data format to resolve this issue.
