Navigation system is the order of the day to pilot people to their destination. This paper focuses on the uses of mobile devices such as PDA’s and smart phones without additional hardware to direct pedestrians based on synthetic texturing along with 3D modeling. Each facade is reconstructed by arraying small sized textures in respect to their geometries in different layers. In the process of texture generation cropping, rectifying, removing disturbing objects and exposure setting should be done in advance. Unlimited number of layers with different priorities and their horizontal and vertical pulse functions and texture files can be utilized for creating a simple square looking facade. Each 3D model is created by mapping the synthetic textures on the 3D geometries of each building’s 3D model. The processes to create the synthetic textures as well as their usage in mobiles’ context are described in detail in this paper.
