"""comfyui_mesh_cleanup_oneshot — limpia una malla 3D en una sola llamada.
|
|
|
|
Promocion de la secuencia repetida (issue 0087) del post-proceso de mallas
|
|
Hunyuan3D: decimar a un presupuesto de caras razonable y, opcionalmente, hacerla
|
|
estanca. Capitaliza el "Golden 3" del report 0088 (80k caras + estanca a la vez).
|
|
Compone funciones del registry del grupo `comfyui`:
|
|
|
|
comfyui_simplify_mesh_py_ml (decima conservando apariencia)
|
|
comfyui_make_watertight_py_ml (cierra la malla; solo si watertight=True)
|
|
|
|
Las mallas nativas de ComfyUI/Hunyuan3D salen densas (decenas de MB, >1M caras) y
|
|
NO estancas (VoxelToMeshBasic produce "cube-soup"). Este pipeline las deja listas
|
|
para web/impresion: ligeras y, si se pide, cerradas.
|
|
|
|
Pipeline impuro: lee y escribe archivos en disco. Requiere trimesh + pymeshlab +
|
|
scipy (simplify) y, para method="voxel", scikit-image (make_watertight).
