Abstract: A method has been put forward using universal software (Adobe Photoshop and Milkshape 3d) and related game software (The sims2 and its components) to complete the 3-D fashion design. It analyzes the superiorities and then gives some examples to analyze how to carry out the 3-D fashion design. To begin with, the fashion style should be completed and the model should be chosen from the game software and be adjusted according to fashion style, then the basic sketch will be realized through UV mapping. Finally, the unity three dimensional fashion designs will be accomplished with the design of fashion scene and fashion space. The results indicate that the method meet the demands of 3-D fashion design to a certain extent, and can achieve the 3-D fashion design, the setting of fashion scene and the design of fashion space.
