I wondering what the difference is between a sprite sheet and a texture atlas?
Aren't both the same? In a sprite sheet you have some Sprites and in a texture atlas you also have some sprites, so what's the difference?
A sprites-sheet (often refers to a large image that) is supposed to contain the
A texture-atlas is (often taken to mean something that's) supposed to contain
Also, it may be important to note a texture atlas often contains character skins (character textures) and the actual animation is not stored as 2d imagery in such cases as the animation is such cases is generally based on deformation of the mesh with tools like bones.
Technically seen it's the same: It's a big image that contains smaller images (sprites).
The 3d vs 2d does not make a difference here since almost all 2d game engines use 3d hardware for rendering....
