: Stereo line drawing. (a) each-eye-based lines, (b) our lines, (c) each-eye-based stylization, (d) our stylization, (e) our result combined with toon shading. Binocular rivalry occurs in several regions (e.g., wrinkles) in (a) and (c), whereas our method eliminates such artifacts in (b) and (d) by using stereo-coherent lines and stylization. Stereo images in this paper can be viewed using red/cyan 3D glasses. This paper discusses stereoscopic 3D imaging based on line drawing of 3D shapes. We describe the major issues and challenges in generating stereoscopic 3D effects using lines only, with a couple of relatively simple approaches called each-eye-based and centereye-based. Each of these methods has its shortcomings, such as binocular rivalry and inaccurate lines. We explain why and how these problems occur, then describe the concept of stereo-coherent lines and an algorithm to extract them from 3D shapes. We also propose a simple method to stylize stereo lines that ensures the stereo coherence of stroke textures across binocular views. The proposed method provides viewers with unique visual experience of watching 2D drawings popping out of the screen like 3D.
Kim et al. REF provided a method to create S3D line drawings from 3D shapes.
