process_mesh обрабатывает сохранённую сетку через GeometryKernel и обычный путь команд агента. Методы: clean удаляет точные дубликаты и вырожденные треугольники; remove_small_components удаляет малые компоненты связности по рёбрам; orient согласует обход, отклоняя неподходящую сетку; repair_orientation удаляет конфликтующие треугольники; smooth выполняет Taubin-сглаживание с фиксацией открытой границы. Лимит — 200000 треугольников. Каждая операция сохраняет новое тело и полноразмерный PLY, исходники остаются. Это не заполнение дыр, не проверка самопересечений и не превращение в B-rep.

The discovered process_mesh command takes body_id, method and optional
parameters. It works through the shared GeometryKernel, Command System,
revision-checked Agent API and MCP command wrapper. These are agent tools;
the browser tree shows only operations actually used and their saved results.
| Method | Parameters | Behavior |
|---|---|---|
clean |
{} |
Weld exact duplicate XYZ vertices, remove duplicate and zero-area triangles, compact unused vertices. |
remove_small_components |
{min_triangles} |
Remove edge-connected components smaller than the explicit threshold (1–100000). Sharing only a vertex does not join components. |
orient |
{} |
Make winding consistent within each edge-connected component. Reject non-orientable or non-manifold input. Does not claim outward orientation. |
repair_orientation |
{} |
Cut conflicting triangles from non-orientable parity cycles, then orient retained triangles. Report deleted triangle count. Creates additional open boundaries rather than inventing patches. |
smooth |
{iterations, strength} |
Taubin passes with factors strength and -1.05 * strength, 1–10 iterations, strength in (0, 0.5]. Pin all open-boundary vertices. Reject degenerate, non-manifold or inconsistently oriented input, and triangle foldovers relative to the input. |
Operations accept triangle meshes with at most 200000 triangles. A result must retain triangles and cannot introduce additional zero-area triangles or non-manifold edges. Smoothing also checks the persisted float32 result. It is not a self-intersection certificate or an exact shape-preserving operation.
Each operation creates a new source-linked body, hides its source, and saves a full-resolution hashed PLY. It records method, parameters, source geometry hash, previous feature and before/after counts, edge-connected components, boundaries, winding inconsistencies and degeneracies. Smoothing reports actual maximum vertex displacement in unchanged source coordinates. Original bodies and PLYs remain available. Incompatible source edits fail persisted validation while descendants depend on the original geometry hash.
These operations do not fill holes, infer physical scale, convert a mesh to an OCCT solid, or prove freedom from self-intersections. Historical operations are inspection records; append another operation to create another result.
