Three dimensional structure is 3D configuration based on the study of three dimensional space. On the basis of following the principle of form beauty, a brand-new, with a sense of beauty, a 3D morphological process can be created. Moreover,most modeling of interior space shows the combination of a variety in form and structure. The form and structure is created by dots, lines, faces and shapes ＂from the three-dimensional elements. In the process of interior design, an innovative interior space environment can be created with the combination of aesthetic principles in three dimensional structure.
