# Mesh Module

Apply texture atlases to 3D meshes

## Purpose

- Remap mesh UVs to atlas coordinates
- Transform meshes with new textures

## Layout

```
mesh/
├── context.md   # This file
├── __init__.py  # API: apply_atlas()
└── uvmapper.py  # UV remapping logic
```

## Scope

- In-scope: UV remapping, mesh transformation, vertex duplication
- Out-of-scope: Mesh loading, color extraction

## Entrypoints

- `apply_atlas(mesh, atlas, color_to_uv, mapper, face_colors)` - Main application
- `apply_atlas_to_mesh(mesh, atlas, color_to_uv, mapper, face_colors)` - Detailed UV remapping with cached colors

## Dependencies

- Internal: extraction.reader (for get_face_colors)
- External: NumPy, trimesh
