Non-photorealistic graphics means computer graphics that do well enough without attempting to make images that look like camera images. An example is conferencing. For example, if we track lip movements, we can generate the right animation to fit our face. If we don’t much like our own face, we can substitute another one—facial-feature modeling can map correct lip movements onto another model. See if you can find out who is carrying out research on generating avatars to represent conference participants’ bodies.
