Evaluation of 3D semantic segmentation performance on the ShapeNetPart dataset using prompt-based evaluation methods, reporting canonical and rotated mIoU metrics.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Promptable 3D semantic segmentation |
| Dataset (including any stated split) | ShapeNet-Part |
| Metric | mIoU (Canonical, Part of Obj.) |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.
