High-likeness humanoid character generation from a single portrait for `img2threejs`.

Technical Positioning
Achieving photorealistic or highly recognizable human character models from minimal input, expanding the product's capabilities into advanced digital human creation. Integrating sophisticated 3D graphics and photogrammetry techniques.
SaaS Insight & Market Implications
This issue outlines a significant leap for `img2threejs` into high-fidelity digital human creation, moving beyond its current stylized-only character generation. The motivation is to produce recognizable, animation-ready human models from single portraits, a complex challenge requiring advanced 3D graphics and photogrammetry techniques. For B2B SaaS, this capability unlocks high-value markets such as virtual avatars, digital doubles for entertainment, and personalized marketing content. The emphasis on per-region confidence reporting and animation-ready rigs demonstrates a commitment to production-grade output. This strategic enhancement positions the product to compete in the demanding digital human market, where photorealism and animatability are paramount, significantly expanding its addressable market and perceived value.

Human generation: high-likeness humanoid characters from a single portrait

## Motivation

Today the character track is deliberately **stylized-only** — humans come out as game/figurine avatars, not photoreal likeness (a documented limit). The next leap for the project is turning a single portrait into a recognizable, animation-ready human.

## Scope

Wire the **projection-first likeness path** end to end into the character render:

- Solve the reference camera and camera-match the render (`scripts/solve_reference_camera.py`).
- De-light the photo to a neutral albedo before projection (`scripts/delight_reference.py`).
- Project the reference onto the fitted mesh (`scripts/bake_projected_texture.py`) using landmarks from `scripts/extract_reference_landmarks.py`.
- Report **per-region confidence** and request more views when a region is under-constrained.
- Stretch: a true humanoid rig (SkinnedMesh + morph targets) so the result can be posed/animated.

## Pointers

- `references/character-reconstruction.md`
- `references/likeness-maximization.md`
- `ROADMAP.md` (v1.3 Likeness maximization, v1.4 Animation-ready rigs)

## Acceptance criteria

- A real portrait photo produces a recognizable stylized-realistic human demo in the showcase.
- The pipeline emits a per-region confidence report and honestly flags low-confidence regions.
- No regression to the existing object/character pipelines.

**Difficulty:** hard · **Good for:** someone with 3D graphics / photogrammetry interest. Design discussion welcome before coding.
