Inputs (7)
| Name | Type | Default | Description |
|---|---|---|---|
| trimesh | TRIMESH | — | |
| target_face_count | INT | 50004–10000000 | Target number of output faces. |
| quality_threshold | FLOAT | 0.300–1 | Quality threshold for edge collapse. Higher = more conservative, better triangle quality. |
| preserve_boundary | COMBO | true | Preserve mesh boundary edges during decimation. |
| preserve_normal | COMBO | true | Prevent face normal flips during decimation. |
| preserve_topology | COMBO | true | Preserve mesh topology (genus) during decimation. |
| planar_quadric | COMBO | false | Add penalty for non-planar faces. Helps preserve flat regions. |
