| 摘 要： | 在探讨三维Morphing(形状过渡)技术的基础上,提出了一种带不失真纹理映射的牙膏体构造法,较详尽地阐述了三角网格剖分算法的思想.牙膏体是一个包含帽体和膏体两部分的复杂曲面体,从顶部圆台过渡到中间圆面、最后过渡到底部一条直线,它们在拓扑结构上是同构的,因此能通过OpenGL的顶点数组编程加以实现.这种组合曲面造型法不仅方便,还提供丰富的参数选择,具有一定的应用意义,也能有效应用于二维半形状、火箭体和鱼类等绘制.

| Abstract: | Based on exploring the fundament of 3-D morphing technology,a method of tooth-paste object modeling with distortion-less texture mapping is put forward,and the arithmetic idea of triangular subdivision is explicated in detail.The tooth-paste object consists of a cap and a body,whose the first part is a truncated cone of the cap,the second part is a cylinder of the body and the last part is a line at the bottom.All the 3 parts are isomorphic in topology,so the tooth-paste object is realized via handling vert... |
