Think about how Adobe Flash deals with inbetweens. You take two images next to each other, and have a tweener program fill in the rest. This is all happening in, like, a fourth of a second, but it's still happening. It's all programming.
When I said "without drawing" I meant "the amount to be drawn will be severely limited."
Instead of drawing each frame, they instead create a 3D renderable model that is full 3D and movable. Think of a figurine in a computer program. That model has to be manipulated by hand until a finished product is created, and then they can just reuse that model forever and ever until they create a newer one with, like, different clothing or something.
But the point to make here is they can now use 3D to pose a figure which is then rendered with an outline and coloring and other added effects to effectively create something that looks like a 2D image. Then they move it about to match 24 frames per second (or whatever they do in traditional animation) and other than the style of the characters we're tricked in to believing it's a 2D animation.
They get the style and 2D feel they want. They also get to save money and time by using 3D models and advanced programs. We complain about the style of art, but grow use to it in time, then LOVE it forever.
Everyone wins.
