摘    要:浮雕是一类将细节附着在平面或曲面背景上的复杂曲面,设计时其背景大多为平面,应用时根据需要将其粘贴在不同的三维产品表面上,这就是浮雕曲面的粘贴问题。将浮雕和目标物体均用三角网格模型表示,提取粘贴的区域作为目标曲面并将其参数化到一个平面上,建立浮雕附着的平面与目标曲面之间的关系,然后设计一种法矢调整算法使得浮雕在目标曲面上变形较小,最后将浮雕和目标曲面合成为一个完整的三角网格。所提算法不仅适合形状变化平缓、曲率小的目标曲面,对于曲率大的目标曲面也有较好的粘贴效果。

关 键 词:浮雕曲面  剪切粘贴  网格编辑  曲面参数化

Abstract:Relief is a kind of complex surface where the detail is attached onto a flat or curved background surface.The detail is usually designed on a plane background and then pasted onto 3D shapes for various applications,which is defined as a relief pasting problem.In this paper,both relief and target object were expressed as triangular mesh models.Firstly,an area on the target object was specified and parameterized onto a plane,so the relationship between the source relief and the target area was established.Sec...
Keywords:relief surface  cut-and-paste  mesh editing  surface parameterization
