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.%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. Secondly, an algorithm based on normal vector adjustment was designed for relief wrapping on the new base with less distortion. Finally, the relief and the target area were integrated into a complete triangular mesh. The proposed method is not only suitable for the target surface with a shape of flat or small curvature, but also has a good result for the target area with large curvature.
