Interactive Generation of (Paleontological) Scientific Illustrations from 3D-models
(The Eurographics Association, 2012) Schäfer, Sebastian; Knopp, Christoph; Krömker, Detlef; Isabel Navazo and Gustavo Patow
Scientific illustrations play an important role in the paleontological domain and are complex illustrations that are manually drawn. The artist creates illustrations that feature common expressive painting techniques: outlines, both irregular and periodic stippling as well as an abstract shaded surface in the background. We present a semiautomatic tool to generate these illustrations from 3D-models in real-time. It is based on an extensible GPU-based pipeline to interactively render characteristic into image-layers that are combined in an image-editing fashion. The user can choose the techniques used to render each layer and manipulate its key aspects. Using 3D- and 2D-painting the artist can still interact with the result and adjust it to his or her liking.
