利用骨架的三度空間物體變形

Abstract

本篇論文是在討論三度空間中物體變形的方法。為了在使用者手動與程式自動化間取得良好的平衡，並能產生令人滿意的變形，我們利用三度空間物體的骨架以及重心來作為輔助，以減少使用者的手動。將物體進行分裂，使得對應關係的產生得以較快速且容易的產生。最後簡化問題的複雜度，將物體對應至二度空間，尋找物體間的對應點，以重建新的物體來產生變形。

This paper proposes a method about the three-dimensional geometric metamorphosis. In order to balance between automatic generation and manual interaction and produce a satisfying metamorphosis, we use the skeletons of objects to assist and reduce the manual interaction. On the other hand, the skeleton can split the object thus making the correspondence mapping easier and faster. Furthermore, to reduce the complexity of the problem, we map the split three-dimensional objects to two-dimensional ones. We then use the two-dimensional objects to find the correspondence between objects, reconstruct new objects, and finally morph.
