1. Sentence: We show how 2D vector art drawings of a cartoon from different views can be used to generate a novel structure, the 2.5D cartoon model, which can be used to simulate 3D rotations and generate plausible renderings of the cartoon from any view. (sentence 2 paragraph 1)
2. Problem: It is easy to rotate 3-D models but it is difficult to rotate a 2-D vector drawing.
3. Key Idea: Represent each pen stroke in 3D, transform each stroke in 3D but interpolate the stroke in 2D for the final rendering.
4.a What the paper does: Provides a method for rotating vector drawings without a complete 3D model of the characer.
4.b What could it be used for: Generating a movie that looks hand drawn without having to model a complete character.
