Study on realistic texture mapping for 3D models

This paper discusses the comparison of the visual appearances of 3D texture models. In this paper, we collected ten 3D digital models and each model is illustrated by three types of texture maps, says diffusion, bump and normal maps. All of these models are created by the image-based modeling method. In most cases, the normal map will improve the visual reality of 3D model appearance. However, the bump map and normal map, that are generated by software, may fail in specific conditions. Nevertheless, it is worth for improving the quality in rendering a 3D model.
