orthographic-registration
Register front, side, back, and top orthographic reference views into a shared Blender coordinate contract. Use when a 3D model must match multi-view wireframes/templates, when side/back/top silhouettes are off, or before adding depth to a front-locked contour model.

What does this agent skill do?
Orthographic Registration
This skill prevents the common failure where the front view looks plausible but the side/back/top views are wrong.
Coordinate contract
- Front view defines
X/Zsilhouette. - Side view defines
Y/Zdepth envelope. - Top view defines
X/Yspread. - Back view defines rear silhouette/material only; it must not rewrite the front silhouette.
Workflow
- Run
scripts/register_views.pyon the available view images. - Create orthographic reference planes/image empties with a single shared scale.
- Align centerline and bbox centers before modeling.
- Lock front X/Z boundary vertices.
- Add Y depth from side/top envelopes using modifiers/displacement or vertex groups.
- Validate all four cameras before export.
Failure policy
If views disagree, front brand read wins. Document the conflict in registration_report.json.
Front-plane rotation rule
In this Blender coordinate convention, the front camera looks along the Y axis and the reference silhouette lives in the X/Z plane. Therefore 2D rotations inside the front view are rotations around the Y axis, not around Z. Use rotation_euler = (0, angle, 0) for 2D component orientation in the front projection. Z rotation spins objects into/out of screen-space incorrectly for X/Z-plane meshes.
Sources distilled
- Blender Image Empty/reference image controls for orthographic blueprints.
- OpenCV homography/alignment and geometric transforms for view registration.
