+# NL3D anonymized review sample
+
+This repository contains an anonymized review-time sample of the NL3D real benchmark. It is intended to let reviewers inspect the data organization and annotations during the double-blind review period; it is not the complete real benchmark.
+
+The sample contains two metallic and two transmissive scenes:
+
+- `real_sample/metal/scene_fish1`
+- `real_sample/metal/scene_statue`
+- `real_sample/transmissive/scene_bird`
+- `real_sample/transmissive/scene_banana`
+
+Each scene provides RGB observations in `color/`, registered depth observations in `depth/`, calibrated intrinsics in `intrinsics.json`, and ground-truth object geometry in `GT_mesh.stl`. The `annotations/` directory contains quasi-ground-truth FULL_OPENCV camera poses, the final global object Sim(3), frames used for refinement, refinement summaries, per-frame silhouette scores before and after refinement, and final rendered masks.
+
+`scene_bird` contains 100 RGB/depth captures. Its optimization-frame list and final rendered-mask set contain 97 valid frames; three captures were excluded from the refinement stage and are retained only as raw observations.
+
+The full benchmark contains additional scenes and artifacts that are withheld during the anonymity period. The complete release will be restored after double-blind review.
