3D Reconstruction Based on Breaking Recurrently down Orthographic Views with Selected Orthographic Face;

Research on Gradedly Reconstructing 3D Models from 2D Orthographic Views;

Then mechanisms and algorithms to form orthographic views are described for this specific way of cube-based 3D modeling.

This article theoretically analyzed no setting three views formations and characteristics,as well as no setting three views judgment methods,and carried on the analyses to no setting three views configurations.

The three views of the compound entity are founded in engineering drawing.

According to the cartography standard of our country, some methods by using Auto CAD to draw three views rapidly and exactly, and guarantee the projection rule among three views are put forward in this paper.

For tori, the projection characteristics in three orthographic views are analyzed; the unique conic features in different projections are accordingly defined as primary and secondary features.

There are various combination of objects which draw by computer in three orthographic views for even one solid model and there possibly is projection mistake between objects in three orthographic views.

By using the cross point of the bisector and arc of a big circle as a medium value in two cores, the tool of Origin is employed to draw a 3 -D draft and 3 views on the 3 projection planes.

This article also introduces the thought of solving engineering graphic problems with mathematical methods and emphasizes the solution to three view problems in engineering graphics by using mathematical theories.

The algorithm technique of dress recognition of model posture based on the three dimensions view is put out in this paper.
