1. A system for a mosaic rendering of a 3D (three-dimensional) model, comprising: an input module inputting a 3D model; a texture creating module creating textures using polygon information of the inputted 3D module; a mapping module one-to-one mapping the created textures on respective polygons of the 3D model, using a geometric structure of the inputted 3D model; and a rendering module rendering a mapped mosaic image.
