Research On 3D Modeling Method Based On Free Deformation Algorithm

The application of 3D printing technology in the educated field has been widely concerned,as it has a rapid development.In the primary and secondary school,3D printing and creative education has received severely hampered for existing professional 3D-modeling softwares are badly suitable for primary and middle school students with lower geometrical and spatial ability.In this study,to match the level of primary and middle school students and reduce the difficulty of operation,in this study,a novel interactive mode designed with intuitive and convenient,it has practical value of engineering.3D printing and Maker Education is conducive to cultivating primary and middle school students' creativity and imagination.So,researching the 3D modeling software which is matching the students of primary and middle school has the great significance.This study mainly analysis primary and secondary school students' ability in geometrical space and 3D modeling technology,summarizes the basic and essential characteristics of primary and secondary school students' three dimensional modeling software,analysis 3D model deformation editing.In addition to this,we designed the deformation editing interactive mode based on the point-dependent free deformation algorithm,and according to the editing interaction and deformation of the calculation of different rules,we designed several tool styles of deformation editing.Besides,we designed experiments to verify the deformation editing tool to edit the model to meet the needs of 3D printing.What's more,we designed two kinds of grid subdivision rules are designed for linear and nonlinear,and designed experiments to the deformation quality and time-consuming condition of different subdivision degree.In the experiments,we give the grid breakdown threshold to control the software response speed within 500 ms.Beyond all that,we designed and achieved the Web platform three-dimensional,deformation editing modeling system,in which we integrated deformation editing methods,grid segmentation rules and commonly used three-dimensional software functions.In this study,the research of 3D-modeling software,which is face to primary and secondary students,put forward that an interactive mode of 3D model deformation editing with do without selecting characteristic points or creating control grid.Users can carry out 3D-modeling similar to ‘shape plasticine'.It is suitable for primary and secondary students,who has poor ability of spatial ability of imagination and construction.
