Non-Photorealistic Rendering for Aesthetic Virtual Environments

摘要: The line integral convolution (LIC) method, originally developed for imaging vector fields in scientific visualization, has the potential to produce images with directional characteristics. In this paper, we present four techniques explore use of LIC generating style Impressionists. particular, develop an Impressionist Line Integral Convolution algorithm (ILIC) generate impressionist styles. This takes advantage information given by a photographic image, incorporates shading technique blend cool and warm colors into finally applies revised method imitate artists, paintings done Furthermore, propose color fidelity technique, which cool-to-warm scheme, initiating artists’ conventional painting enhance visual depth perception. We also preservation quantifies image details control length, making it possible preserve subtle during process. Finally, demonstrate top-down sampling where series artistic mip-maps is generated construct aesthetic virtual environments. These maps provide constant strokes cues, thus achieving frame-to-frame coherence interactive walkthrough system. Both silhouette drawing tour picture (TIP) approaches are employed user’s immersion world. experimental results merits our styles constructing system that provides experience rendered
