Abstract: The invention proposes a method for displaying an image based navigation route corridor for 3D view on mobile platforms for mobile users. The invention comprises the combination of some technical solutions. 1. Display of a relevant area around a selected or calculated route (route corridor). 2. Selection of the relevant area that is a small dataset. 3. Creation of the customized route corridor dataset. 4. Provide 3D viewers ability to allow the display of the created route corridor in 2D, isometric view, or 3D perspective and then allow 3D maneuverability over the created route corridor. Combination of these technical solutions comprises a method of facilitating the display of the route corridor on mobile computing platform in 3D perspective.

Abstract: The present invention relates to computer graphics. This method allows efficient real-time 3D rendering of high-detail smooth surfaces. It is exceptionally effective with software rendering and low-end weaker graphics accelerators, and provides excellent visible quality per the amount of polygons used, while retaining low CPU processing overhead and high efficiency on graphics hardware. Also, it can be used under very restrictive memory requirements. In particular the invention relates to real time rendering of extremely detailed smooth surfaces with view-dependent tessellation using an improved level of detail approach. The invention utilizes a quad-tree map and geometric boundaries consisting of manifold non-self-intersecting surfaces. All cached fragments keep all of the information loaded from their corresponding source nodes in system memory, and additional information computed by the rendering system.

Abstract: Dynamic visualization of image data provided through a network communications channel is performed by a client system including a parcel request subsystem and a parcel rendering subsystem. The parcel request subsystem includes a parcel request queue and is operative to request discrete image data parcels in a priority order and to store received image data parcels in a parcel data store. The parcel request subsystem is responsive to an image parcel request of assigned priority to place the image parcel request in the parcel request queue ordered in correspondence with the assigned priority. The parcel rendering subsystem is coupled to the parcel data store to selectively retrieve and render received image data parcels to a display memory. The parcel rendering system provides the parcel request subsystem with the image parcel request of the assigned priority.
