Analyze the supplied single character image for a Spine cutout animation pipeline.
|
|
Return a JSON part plan, not an image. Preserve the exact pose, asymmetry, clothing,
|
|
and screen-left/screen-right orientation. Do not require a fixed number of parts.
|
|
Use stable lowercase ASCII IDs (letters, numbers, underscores, hyphens).
|
|
Separate parts only where independent motion is useful and the image supports it.
|
|
You are a semantic planner, not a pixel-grounding detector.
|
|
rig_role is bone_part for articulated body segments, attachment for clothing/hair/props,
|
|
or facial_feature for eyes, eyebrows, nose, mouth and mustache. Facial features and
|
|
decorations do not each need a bone. For bone_part, parent refers to another bone_part
|
|
or null for the future root, and bind_to must be null. For attachments/facial features,
|
|
bind_to is the existing bone_part driving the slot (or null for root); parent is the
|
|
semantic parent. Bind sleeves to the appropriate upper arm, facial features to head.
|
|
Occlusion is a separate relation: occluded_by lists parts visually in front.
|
|
All coordinates are normalized to the full supplied canvas, including transparent
|
|
margins. bbox_norm_xyxy is [xmin,ymin,xmax,ymax], never [x,y,width,height].
|
|
pivot_norm is a ROUGH kinematic joint estimate: it may be occluded or outside foreground.
|
|
For visible or partly visible parts give only a coarse visible bbox.
|
|
Leave positive_points_norm=[] and negative_points_norm=[]. The program generates
|
|
foreground candidate seeds from alpha inside each ROI. Being on the character
|
|
does not prove a seed belongs to the intended part. Do not invent precision.
|
|
Do not claim precise pixel masks. A segmentation stage will refine boundaries.
|
|
If a part is fully hidden, mark visibility="hidden", bbox_norm_xyxy=null,
|
|
positive_points_norm=[], needs_completion=true and explain the uncertainty.
|
|
completion describes texture required to move independently from this pose:
|
|
- occlusion_fill: true for partial or hidden parts, including shoulders behind sleeves.
|
|
- joint_extension_parent: whether this bone part needs overlap at its parent joint.
|
|
- joint_extension_child: whether this bone part needs overlap at a child joint.
|
|
Attachments/facial features have both joint_extension flags false.
|
|
needs_completion must be the logical OR of these three flags, not just fully hidden.
|
|
Do not invent hidden limbs or accessories without visual evidence. Put assumptions
|
|
in notes. Confidence is your uncertainty estimate, not a measured segmentation score.
|
|
Avoid cycles in parent and occluded_by relations. If an object crosses in front
|
|
and behind another, split its visual layers or flag the ambiguity in notes.
|
|
Return schema_version=2, coordinate_space="normalized_xy_top_left", parts, notes.
