+# CMU backward locomotion source
+
+`_cmu_locomotion.glb` contains one animation-only clip:
+
+- `RunBackward` — CMU Graphics Lab Motion Capture Database, subject 76,
+  trial 11: “quick large steps backwards.”
+
+Source BVH:
+https://github.com/una-dinosauria/cmu-mocap/blob/master/data/076/76_11.bvh
+
+Original motion database and trial description:
+https://mocap.cs.cmu.edu/
+
+The BVH is Bruce Hahne’s conversion of the original CMU motion-capture data.
+CMU’s FAQ permits copying, modifying, and redistributing the data (including
+commercial use), requests acknowledgment, and prohibits selling the database
+itself. This project uses a cropped, in-place gait cycle as part of the game,
+not as a standalone resale of the database.
+
+Build command:
+
+```text
+blender --background --python tools/build_cmu_locomotion_library.py -- 76_11.bvh assets/characters/animations/_cmu_locomotion.glb
