| 摘 要： | Texture pattern mapping is one of the most important techniques for high quality image syn-thesis. It can largely enhance the visual richness of raster-scan images. In this paper is presented a newmethod of mapping planar texture pattern onto beta-spline curved surfaces——bilinear mapping methodwhich can map planar texture pattern onto curved surfaces with less distortion, and also can fulfill thegeometric transformation of the texture pattern on the curved surfaces by operating the pattern win-dow. It is valuable to both CAD/CAM in artistic field and computer graphics.
