Texture Expansion Auxiliary System Of Utensils

It has been a trend to study objects and protection with computer graphics technology.Archaeological drawing is a method,which adopts cartography to study,record and explain archaeological materials.Traditional archaeological projection drawing requires draftsman to master the skills of professional archaeological knowledge,sketch foundation and the method of projection mapping,or it is difficult to serve for archaeology correctly and scientifically.In order to further study the implements of pattern,organization structure and its artistic style,it is needed to expand the decorative pattern of artifacts.But it spends more time,manpower and material resources for traditional archaeological projection drawing,and in the drawing process,it will inevitably cause some wear and tear on the surface of objects.According to the actual shape painting on the plane,the surface of spatial object is called the three-dimensional surface,the unfolded graphics are called threedimensional surface graph of the object.In order to reflect the original appearance of objects,the graph must be drawn with the principle of the orthogonal projection according to its expandable and un-expendable surfaces.This system is to realize the segmentation unfolding of the 3D objects model surface ornamentation.In the final analysis,it is a triangular mesh parameterization problem,but they are different.In order to better meet the needs of users,the system not only can divide and deployed the 3D model texture automatically,but also can section and unfold ornamentation interactively with users setting the position of the cutting plane,the number and unfolding pattern of each a short period of texture.Compared with traditional archaeology projection drawing,this system has concise interface design and is convenient to operate.It can save a lot of manpower and material resources,reduce not only requirement of drawing workers but also the damage to objects in the process of hand-painting to a great extent.
