一种新的三维模型表示与存储方法

A New Method for the Representation and Storage of 3D Model

利用三维模型三角面片的点面信息,对模型进行基于体素的规格化表示,重新构建三维模型。对在同一平面的相邻两个规格化三角面片进行合并,构成新的四边形面片,由此获得由三角面片和四边形面片混合显示的三维模型。分别对三角面片和四边形面片进行分类和编码,探索三角面片与四边形面片混合存储的方法。实验结果表明,该方法能够在规格化三角面片存储方法的基础上,进一步压缩三维模型的存储空间,提高存储效率。

The original 3D model is reconstructed by normalizing the original triangle patches of 3D model ac-cording to the point and patch information of the 3D model. The representation of 3D model is the blend of the normal-ized triangular and quadrilateral patch which is produced by merging the two normalized triangular located in one plane. The blend storage method of the triangular and quadrilateral patch is explored by classifying and coding the triangular and quadrilateral patch. The experiment result shows that the proposed method could make further efforts to reduce the storage space of 3D model effectively and improve the storage efficiency compared with the storage method of normal-ized triangular patch.
