英文摘要： 3D modeling technology has a wide range of applications on mobile terminals including tablet PCs and smart phones. However, due to the limitations of the computing power, screen size, input device and interaction method, it is difficult to apply traditional 3D modeling technologies to mobile terminals directly. The project intends to conduct research on a sketch based 3D modeling technology for mobile terminals. Four topics are included in the research. Firstly, key theories and technologies of a sketch-based 3D modeling method will be studied to realize fast and convenient 3D model design. Secondly, a 3D painting method based on a dynamic surface parametrization technology is proposed to directly draw textures on the surface of a 3D model in real time using a 2D painting style. Thirdly, based on the characteristics of the touch input method of mobile terminals and the sketch-based modeling method, human-computer interaction techniques based on gesture operations are studied to achieve natural and friendly 3D design. Finally, a prototype system of sketch-based 3D modeling run on mobile terminals will be developed, and user evaluation will be given. The key techniques to be researched will break through the limitations of traditional 3D modeling methods, explore new 3D modeling and human-computer interaction technologies based on the methods of sketching and gesture operations, improve the efficiency of 3d modeling design, enhance the user experience, and provide theoretic foundation and technique support for applying 3D design technologies to mobile terminals.
