Interactive Projective Texturing for Non-Photorealistic Shading of Technical 3D Models

Lux, Roland; Trapp, Matthias; Semmo, Amir; Döllner, Jürgen in Proceedings of 11th Theory and Practice of Computer Graphics 2013 Conference (TP.CG.2013) Czanner, Silvester; Tang, Wen ( Eds. ), page 101--108 . The Eurographics Association , 2013 .

This paper presents a novel interactive rendering technique for creating and editing shadings for man-made objects in technical 3D visualizations. In contrast to shading approaches that use intensities computed based on surface normals (e.g., Phong, Gooch, Toon shading), the presented approach uses one-dimensional gradient textures, which can be parametrized and interactively manipulated based on per-object bounding volume approximations. The fully hardware-accelerated rendering technique is based on projective texture mapping and customizable intensity transfer functions. A provided performance evaluation shows comparable results to traditional normal-based shading approaches. The work also introduce simple direct-manipulation metaphors that enables interactive user control of the gradient texture alignment and intensity transfer functions.
