Relational transparency model for interactive technical illustration

Abstract

Ghosted views are technical illustrations that communicate not only shape, but also inner structure and spatial relations of the depicted objects. Modulation of opacity is utilized to communicate the inner structure, therefore the spatial relations remains undistorted. In this paper an approach that enables real-time rendering of 3D ghosted views is presented. The advantage over classical handcrafted ghosted views is that the user is able to interact (e.g. pan, zoom and rotate) with the 3D model. ©Springer-Verlag Berlin Heidelberg 2008.
