Abstract:
Systems and methods for rendering a view-dependent texture in conjunction with a three-dimensional model of a geographic area are provided. A view-dependent texture can be rendered in conjunction with at least portions of the three-dimensional model. A base texture can be rendered for portions of the three-dimensional model in the same field of view that are viewed from a slightly different perspective than a reference direction associated with the view-dependent texture. For instance, a stretching factor can be determined for each portion of the three-dimensional model based on the reference direction and a viewpoint direction associated with the portion of the three-dimensional model. A base texture, a view-dependent texture, or a blended texture can be selected for rendering at the portion of the three-dimensional model based on the stretching factor.
