Abstract.We have proposed the unique method of creating the realistic objects and the architectural elements in virtual space in this paper. To satisfy the requirement of saving time and upgrading the quality of realistic digital contents, we have searched about the efficient way to make color constancy in the UV map from many photos and the realistic material presentation methods. Furthermore, in order to achieve the high reality sense of user in virtual space, we have focused on the interactions between human and virtual objects during the virtual space experience. The interaction will be one of the main factors which effects the realistic perception and cognition of user in virtual space.
