Abstract: Some embodiments of the invention provide methods for generating navigation presentations that display a device navigating a route on a map. The method uses a virtual camera that, based on detected changes to the navigation context, dynamically modifies how it captures map portions to produce navigation scenes in the presentation. The method of some embodiments identifies attribute sets describing different navigation contexts and uses these attribute sets to identify virtual camera operating styles. The method uses an identified style to specify the virtual camera's positional attributes, which define the map portions identified for rendering to produce navigation scenes over time. During the navigation presentation, each time the navigation context changes, the identified attribute set may change. This, in turn, may cause the method to select a new virtual camera operating style. When the style changes, the method modifies the way the virtual camera captures the map portion to render.

Abstract: Embodiments are directed towards enabling digital cameras to create a 3D view, which can be re-rendered onto any object within a scene, so that it is both in focus and a center of perspective, based on capturing a single set of multiple 2D images of the scene. From capturing a single set of 2D images for a scene, a depth map of the scene may be generated, and used to calculate principal depths, which are then used to capture an image focused at each of the principal depths. A correspondence between a 2D image of the scene and the principal depths are determined that corresponds to a specific principal depth. For different coordinates of the 2D image, different 3D views of the scene are created that are each focused at a principal dept that corresponds to the given coordinate.

Abstract: Techniques described herein are directed to a system and methods for generating 3D models of an object which accurately depict reflective properties of the object. To do this, an image of an object is captured and a rendered image of the object is generated from the image. The system then generates a lighting effect which approximates an effect of the actual light source on the appearance of the object when the image was captured. A number of rendered images of the object are generated using the lighting effect, each having different visual material property values. Once the rendered images have been generated, the system may compare the generated rendered images to the actual image in order to identify the rendered image which best approximates the actual image. The visual material property values associated with the best approximation are then assigned to the object.

The system then generates a visual representation of the set of polyhedra, wherein each polyhedron is affected by data points that fall into it.
