Computer‐Generated Graphite Pencil Rendering of 3D Polygonal Models

摘要: Researchers in non-photorealistic rendering have investigated the display of three-dimensional worlds using various models. In particular, recent work has focused on modeling traditional artistic media and styles such as pen-and-ink illustration watercolor painting. By providing 3D systems that use these alternative models users can generate renderings their worlds. this paper we present our graphite pencil renderer. We broken problem simulating drawing down into four fundamental parts: (1) materials (graphite paper, blenders kneaded eraser), (2) primitives (individual strokes mark-making to create tones textures), (3) basic techniques used by artists illustrators familiar with rendering, (4) control composition. Each part builds upon others is essential developing framework for higher-level methods tools. parts 2, 3, 4 research. outlining shading. also steps from preparatory sketches finished results. demonstrate capabilities approach a variety images generated
