| 提出了一种基于距离场插值的三维Morphing算法.该方法通过解析距离场来实现三维Morphing,使过渡形体的光滑性不依赖于原模型的离散剖分精度.同时,给出了基于约束点对和变形控制体的交互形状过渡算法,用户可由此直观而方便地对变形过程实施有效的控制.多个变形实例证明,该算法能够方便地实现两个任意定向流形模型间的可控三维Morphing. |

| Abstract: |
| A 3D Morphing algorithm based on distance field interpolation is presented in this paper. This method uses analytic distance field to implement 3D Morphing, which makes the smoothness of the transformation shapes not depending on the discrete accuracy of original models. The interactive Morphing algorithm based on some constrained points and Morphing influence shapes is also given in this paper, which allows users to control Morphing procedures intuitively and conveniently. Several Morphing examples show that this algorithm can generate the controllable transformation shapes between any two oriented manifold models. |
