利用三维矢量线条实现版画设计

Image Engraving Design Using 3D Vector Curves

设计了一种粗细变化的三维矢量线条 ,赋予了线条灵活的变化 ,可以改变局部的线宽、线条局部的走向和扭曲度等 ,并利用矢量线条的粗细变化来体现图像的灰度层次 ,从而达到模拟传统版画的效果 ;同时 。

A new kind of 3D vector curve with scalable width is implemented The local width, orientation and curvature of the curve can be changed easily and flexibly Moreover, the change of vector curve width can be used to represent the grey scale of images, so we can simulate the effect of traditional engraving In addition, a method of generating a certain number of equidistant curves by blending curves is presented
