Abstract

Photorealistic rendering, has been the mainstream rendering technique in computer graphics all the time. However, in some important applications, such as construction, technology, and arts which emphasis the transmission of information, photorealistic rendering may ineffective to display the informative graphics. Being the complement of photorealistic rendering, the goal of Non-Photorealistic rendering (NPR) rather focuses on the realism of pictures, but cares more about artistic characteristics of the work or artist’s performance in artistry drawing. The technical development of NPR is very fast in recent years. According to its form of expression, we can roughly classify NPR into four categories: cartoon rendering, pen-and-ink illustration, technical illustration and painterly rendering. Our work utilizes painterly rendering in NPR as the foundation of this research. Artist’s painting skill and experiences are integrated in the creation framework through the way of texture simulation in painterly rendering. Combining technology advancement and art creation, artists’ painting styles can be effective displayed.
