Abstract: A computer-implemented method for dynamically adjusting rendering parameters based on user movements may include determining viewpoint movement data for a user viewing a rendering of a 3D model at a first time, determining a first level-of-detail at which to render the 3D model based at least in part on the viewpoint movement data at the first time and rendering the 3D model at the first level-of-detail. The method may also include determining viewpoint movement data for the user at a second time, wherein the viewpoint movement data at the second time differs from the viewpoint movement data at the first time. In addition, the method may include determining a second level-of-detail at which to render the 3D model based at least in part on the viewpoint movement data at the second time and rendering the 3D model at the second level-of-detail, wherein the second level-of-detail differs from the first level-of-detail.

Abstract: In one aspect, a computer-implemented method for providing combined multi-dimensional map views may generally include receiving, by one or more computing devices, a first set of geospatial data associated with rendering a two-dimensional view of a first portion of a geographic area, receiving, by the one or more computing devices, a second set of geospatial data associated with rendering a three-dimensional view of a second portion of the geographic area and rendering, by the one or more computing devices, a combined map view of the geographic area based on the first and second sets of geospatial data. The combined map view may include a first discrete map area providing a two-dimensional map view of the first portion of the geographic area and a second discrete map area providing a three-dimensional map view of the second portion of the geographic area.

Abstract: Systems and methods for performing shading operations of a three-dimensional model, such as a three-dimensional model of a geographic area, are provided. According to aspects of the present disclosure, shading operations can be performed based on a curvature of the polygon mesh such that smooth surfaces still appear smooth after shading and such that sharp edges still appear sharp after shading. In particular, a curvature-driven normal is used for shading operations that takes into account the local curvature of the polygon mesh. A curvature factor can be obtained for each vertex in the polygon mesh. The curvature factor for each vertex can be a scalar value that describes the degree of local curvature in the mesh polygons connected at the vertex. The curvature-driven normal for each fragment can be determined based on the curvature factors associated with the vertices in the polygon mesh.
