img2cube
Camera-match a photo from drawn lines, then drop 3D snap points.
You have a photo of a building. You want to model it in Blender â but setting up the camera to match the real perspective is tedious and error-prone. img2cube does it automatically â draw a few lines, click Solve, done.
đĽ Core Features:
- Auto Camera Match: Recover focal length and rotation directly inside Blender using vanishing points (2-VP or 3-VP).
- Real-World Scale: Enter just ONE known measurement (e.g., "this door is 2.1m") and the entire scene scales to match perfectly.
- 3D Snap Points: Click on any drawn line or extension in the photo to place a Blender Empty at the exact 3D position.
- Intersection Snapping: Auto-snap to computed line intersections for pixel-perfect placement.
- 100% Inside Blender: No external apps, no going back and forth.
What's New

Initial release on the official Blender Extensions Store (v1.0.6).
- đ Depth Graph with T-junction support: metric depths now propagate through the entire line network.
- 𧲠Snap to intersections: origin pick and snap points auto-snap to exact computed line intersections.
- đ Extension line clicking: snap points can now be placed on the thin guide lines, not just drawn segments.
- đ Estimated dimensions overlay: toggle to see computed lengths on all segments in real time.
