  16. <p>PLY (Polygon or Stanford Triangle Format) is a file format for efficient delivery and
  17. loading of simple, static 3D content in a dense format. Both binary and ascii formats are
  18. supported. PLY can store vertex positions, colors, normals and uv coordinates. No textures
  19. or texture references are saved.</p></div>
