Why this sample is in the benchmark

Thin, low-texture, elongated objects are the canonical hard case: SfM under-constrains them and 3DGS tends to grow fat splats around them. Also a clean test of scale estimation along one dominant axis.

Acquisition plan

kind local, automatic True, estimated size 3.24 MiB

1. Build geometry 'capsule_pill' with {'radius': 0.12, 'height': 0.9}
2. Render 12 views (orbit @ 128px, fov 45 deg)
3. Shade under lighting: studio, low_key, cool_dusk
4. Write GT mesh, surface points, depth, normals, poses

Fully offline. Ground truth is exact (no SfM, no scan noise).
