| Summary: | 碩士 === 國立臺灣藝術大學 === 視覺傳達設計學系碩士班 === 98 === In Computer-Generated Imagery (CGI), a procedural texture is a computer generated image created using an algorithm intended to create a realistic representation of natural elements. The basic structure of a procedural texture is known as a fractal, which has the feature of randomness and self-similarity. Hence, it is ideal to create the formation of concave and convex seen in natural object surface.
Based on the concepts in optical engineering and visual psychology, the author firstly demonstrates the ways in which visible light and colour are seen and understood by people and the meaning of concave and convex in visual psychology. Secondly, this dissertation gives a brief introduction of fractal mathematics and its application in 3-D computer programs. Thirdly, this dissertation employs fractal mathematics to formulate 3-D procedural textures, which were then rendered to create natural concave and convex visual effect. This dissertation hopes to benefit 3-D CGI designers who are involved in fractal texture.
