I wonder if the 2D faces mean there won't be a 3D version of the show... ?
Two different types of 2D/3D. When speaking about animation, 2D refers to traditional hand-drawn animation starting with pencil sketches (formerly inked and painted on cels, these days scanned and digitally inked and painted in a computer), while 3D refers to animation using computer models that are mathematically 3-dimensional. Either type of animation can be displayed in 2D (like a conventional film or TV image) or in "3D" stereoscopic form, depending on how the image is processed and presented. For instance, Disney's
Tangled was animated in the traditional, hand-drawn way with flat images, but it was made (or processed after the fact) in such a way that it could be displayed stereoscopically with the illusion of depth (although there was a 2D version for ordinary movie screens as well). Conversely,
The Incredibles (like most Pixar films) was animated using 3D computer models, but was projected in 2D.
