## Trees and bushes
- Built with EZ-Tree by Daniel Greenheck (MIT licence, https://github.com/dgreenheck/ez-tree) by
  tools/trees/build-trees.mjs: the models, the impostor atlas and trees.json under models/trees/ are generated
  from its presets. The palms are generated by our own code in tools/trees/generate.html.
- Bark textures under textures/trees/, as shipped with EZ-Tree: oak "bark_brown_02" (Poly Haven, CC0,
  https://polyhaven.com/a/bark_brown_02), pine https://www.texturecan.com/details/588/ and birch
  https://www.texturecan.com/details/221/ (TextureCan, CC0).
- Leaf textures leaf_ash, leaf_aspen, leaf_oak and leaf_pine come with EZ-Tree (MIT). leaf_palm is drawn by
  tools/trees/generate.html and is original to this project.
