Abstract
Systems and methods for rendering a view-dependent texture in conjunction with a polygon mesh to provide a textured three-dimensional model of a geographic area are provided. The view-dependent texture can be optimized for viewing the three-dimensional model from a single reference direction. When a user navigates to a camera viewpoint of the three-dimensional model associated with the single reference direction, the view-dependent texture can be rendered in conjunction with the three-dimensional model to provide a more realistic representation of the geographic area to the user. When a user navigates to a camera viewpoint of the three-dimensional model that is not associated with the single reference direction, a base texture can be rendered in conjunction with the three-dimensional model. The base texture can be optimized based on viewing the three-dimensional model from a plurality of differing viewpoints.
