Assembly Animation — Complete 3-Phase Overhaul

This release brings a fully polished step-by-step assembly animation with three distinct visual phases per step:

Phase 0 — Lift-off from 2D canvas

Each piece starts flat at its exact 2D canvas layout position, then arcs upward via a smooth sin-curve before settling at the fold origin. The opening frame mirrors the 2D layout canvas exactly.

Phase 1 — Paper-fold

Faces rotate around shared fold edges using BFS spanning tree + accumulated Matrix4x4 transforms — true paper-folding simulation.

Phase 2 — Fly toward camera (new in F)

The folded shape translates and scales upward to a staged model position directly above the canvas. Pieces visually grow as they rise (stageScale ≥ 1.2×), giving a clear "flying toward the viewer" effect.

Scene & Camera

  • Unified viewport: 2D canvas plane at bottom, assembled model at top
  • Faint amber ghost of the fully assembled model always visible as destination hint
  • Camera auto-positions on open to frame both planes simultaneously (30°/45° perspective)

Bug fix

  • ToFlatV scale bug fixed: canvas/fold positions now correctly match 3D mesh scale for non-PDO formats (OBJ, FBX, etc.)
