 ## Texture atlas
 
 A texture atlas(also called a spritesheet or an image sprite in 2d game development) is an image
 that contains data from several smaller images that have been packed together to reduce overall
-dimensions. Texture atlasing enables batching for several static objects that share this texture
-atlas and the same material. Batching reduces the number of draw calls. Fewer draw calls results in
-better performance when the game is CPU-bound.
