碩士 === 國立雲林科技大學 === 電子與資訊工程研究所 === 94 === Mountain drawing is an essential part of Chinese water-ink painting. This thesis developed an interactively rendering technique and a real-time touring procedure for landscapes with water-ink painting styles in which the geometric information of the landscapes were acquired from DEM (Digital Elevation Model) terrain files shot by satellites. According to the user’s viewing direction, this system automatically finds the silhouettes of the 3D terrain, which includes the detection of the edges, the determination of the edge’s visibility, and the connection of the near edges to form a complete stroke. After connecting the strokes, this system provides an intelligence interface for users to create stylish painting strokes. Users can adjust the stroke’s texture, the stroke’s thickness, and the stroke’s shadow position and height. They can add some accessories, such as trees, grasses, and small stones, to enhance the stroke’s style as well. Moreover, the system can assist users in painting the inner hatching between the silhouette strokes. The final result is a 3D landscape painting with water-ink styles. When users observing the 3D painting, there are many new strokes being generated due to the change of the viewing direction. This system can record the styles of the existed strokes and randomly compute the styles for the new strokes. In such the way, smooth touring into the 3D painting is possible.
