## 1. 3D assets

The player model, animations, pitch, and goals in `match/assets/`
(`clips.glb`, `goals.glb`, `pitch.glb`, `tpose_sculpted.glb`,
including the textures embedded in those files) derive from the game assets of
[GameplayFootball](https://github.com/BazkieBumpercar/GameplayFootball) by
Bastiaan Konings Schuiling, as distributed in
[Google Research Football](https://github.com/google-research/football)
(`third_party/gfootball_engine`). Both sources release those assets into the
public domain under the Unlicense; modifications made for soccerviewer
(format conversion to glTF, sculpting of the player model) are covered by
this repository's MIT license.
