Deformation And Spline Surface Of Arbitrary Triangular Surface

Triangle mesh surfaces play an important role in model three-dimensional objects,and this paper presents a series of editing algorithms for triangular mesh.It contains movement of any three-dimensional point,the movement of a specific area,keep the shape by adding points and spline calculation.Various methods can be used in combination with interactive window,Get the effective and smooth deformation effect,it provide a variety of means for grid design,the diversity of grid surface design is satisfied.The triangular mesh data stored in the off file includes the three-dimensional coordinate and the sheet number,it takes a lot of time and space to design the curved surface directly.To improve operational efficiency and reduce storage space,this paper proposes a topological connection based on the point,edge,surface Graph data structure.Point movement and area,movement meet the requirements of Surface tension deformation,The computation of polyhedral spline satisfies the smoot,hness requirement of surface design.keep the shape by adding points retain the spline geometric details of the original surface after calculation.The design of interactive window meets the practicality of the program,the original grid is compared with the computed spline surface under the interactive window.Finally,texture mapping is made for the generated spline surface,the practicability and stability of the program are verified.
