3d animation means that the characters or things in the animation have a three-dimensional sense, and the performance of the animation has a layered sense, which looks more vivid and real.

Three-dimensional animation is a three-dimensional technology, which is more prominent than 3d animation, and 3d animation also has a three-dimensional effect, but it is limited to the screen. The three-dimensional technology is to make the characters in the screen look like they stand out from the screen, and the two technologies are different.

Cartoons like the one in the picture have no three-dimensional sense, or the angle of the photo is wrong, so they should not belong to the category of 3d.
