应用计算机图象技术复原煤核植物三维形态初探

ON THE APPLICATION OF COMPUTER GRAPHICS TECHNIQUE TO RECONSTRUCT THREE-DIMENSION OF COAL BALL PLANTS

本文报道一种新的复原煤核植物三维形态的途径——计算机三维重建技术。为具体地应用这种技术,本研究发展了三种重建方法:添加法、对称法和混合法。同时,对膜状结构的三维显示方法进行了初探。这些方法的确立对复原煤核植物的形态,建立煤核化石同其他形式的化石间的联系提供了新的有效手段。此外,对应用计算机图象技术复原煤核植物三维形态时存在的问题进行了讨论。

This paper reports a new way by which three-dimensional images of coal ball plants are re- vealed conveniently.In order to reconstruct outer images of coal ball plants,especially se- eds,three different reconstruction methods (additional method,symmetric method and mixed method) have been developed.In the meantime,the way of reconstruction of membrane-like structure was explored. The establishment of these methods contributes to the reconstructing the whole shape of coal ball plants and relating coal balls to other fossil forms.In addition,the difficulties in three-dimensional reconstruction of coal ball plants by using computer are discussed.
