| Track | Full split | Purpose | Models |
|---|
| Toys4K image | 3,218 | Common single-view image-to-3D comparison | All seven |
| Hi3DBench image | 510 image prompts | Object, part, material, and spatial quality | All seven |
| Hard-OOD geometry | 100 fixed GT assets | Chamfer, F-score, normals, and novel-view reconstruction | All seven |
| T3Bench text | 300 prompts | Single object, surroundings, and multiple objects | Native text models |
| Hi3DBench text | 510 text prompts | Hierarchical text-to-3D quality | Native text models |
| Production health | Every artifact | Export validity, latency, VRAM, and failure rate | Every model/track |
| Track | Implemented foundation | Adapter required |
|---|
| Toys4K image | PSNR/MAE, SSIM optional, mesh health, JSONL aggregation | CLIP, DINOv2 FD/KD, ULIP-2, Uni3D, LPIPS |
| Hi3DBench image/text | Artifact protocol and aggregation | Official Hi3DEval object/part/material evaluator |
| Hard-OOD geometry | Chamfer-L2, artifact loading | F-score, normal consistency, fixed GT sampling |
| T3Bench text | Artifact protocol and aggregation | Official T3Bench quality/alignment evaluator |
| Production health | Mesh existence, finite vertices, watertightness, components | Texture coverage, mesh size, peak VRAM, failure taxonomy |
| Phase | Deliverable | Exit criterion |
|---|
| 1 | Freeze manifests, prompt IDs, cameras, seeds, and GLB schema | Every model consumes identical manifests |
| 2 | Finish deterministic geometry/render/health metrics | Clean-environment run succeeds |
| 3 | Integrate CLIP, DINOv2, LPIPS, ULIP-2, and Uni3D | Checkpoint and preprocessing recorded |
| 4 | Integrate official Hi3DEval and T3Bench | Native image/text tracks score successfully |
| 5 | Run all seven models on complete manifests | JSONL, aggregates, failures, and render grids exist |
| 6 | Publish scorecards and qualitative galleries | No silent missing-data averaging |
