Label Layout for Interactive 3D Illustrations

Abstract

Hand-made illustrations in scientific and technical textbooks commonly use internal and external labels or legends\nto establish co-referential relation between pictorial elements and textual expressions. By analyzing the most\ncomplex examples, we extracted several label layout styles and classified them. We propose a variety of real-time\nlabel layout algorithms that aim to produce nice and clean layouts. In order to achieve a frame-coherent label\nlayout during user interactions, the algorithms consider layout decisions from previous frame. Moreover, several\nevaluation criteria to measure the quality of static as well as dynamic label layouts are presented.
