摘　　要：从分析印象主义绘画风格作品入手 ,采用混合笔触设计和立体笔触方法 。A general model of brush strokes with representative key attributes-startpoint, RGB and Alpha values, size, orientation, and appearance is firstset up.Curved strokes are traced along cubic B-spline curves with theircontrol polygon edges normal to the gradient of image intensity. A mixeduse of dots and strokes along with superposition of illumination on colorsare introduced to produce composite and three-dimensional effectrespectively.
