`processing system is contemplated. Conversely, client systems are contemplated
`
`to be conventional personal computer systems and, in particular, mobile, cellular,
`
`embedded, and handheld computer systems, such as personal digital assistants
`
`(PDAs) and internet-capable digital phones, with relatively limited to highly
`
`constrained network communications capabilities. For most wireless applications,
`
`conventional narrowband communications links have a bandwidth of less than
`
`approximately three kilobytes of data per second. Consequently, transmittal of
`
`entire images to a client system in reasonable time is infeasible as a practical
`matter.
`
`Overview:
`
`Description of the Invention
`
`For purposes of the present invention, each image (Figure 1) is at least
`logically defined in terms of multiple grids of image parcels with various levels of
`
`resolutions (Figure 2) that are created through composition of information from
`
`all level of resolutions, and stored by the server to provide an image for transfer
`to a client system (Figure 3). Composed and separate static and dynamically
`created layers are transferred to client system in parcels in a program selectable
`order to optimize for fast quality build-up of the image presented to a user of the
`
`client system, particularly when the parcels are streamed over a narrowband
`
`communication link.
`
`The multiple layers of an image allow the selectivity to incorporate
`topographical, geographical, orientational, and other terrain and mapping
`related information into the image delivered. Other layers, such as geographic
`grids, graphical text overlays, and hyperlink selection areas, separately providedl

`
`or composed, aid in the useful presentation and navigation of the image as
`
`presented by the client system and viewed by the user.
`
`Compositing of layers on the server enables the data transfer burden to be
`
`reduced, particularly in analysis of the requirements and capabilities of the client
`
`system and the connecting communications link. Separate transfer of layers to the
`
`client system allows the client system selectivity in managing and presentation of
`
`the data to the user.
`
`The system and methods of the present invention are designed to, on
`
`demand, select, process and immediately transfer data parcels to the client
`
`system, which immediately processes and displays a low-detail representation of
`
`the image requested by the client system. The system and methods immediately
`
`continue to select, process and sequentially transfer data parcels that, in turn, are
`
`processed and displayed by the client system to augment the presented image
`
`and thereby provide a continuously improving image to the user.
`
`Selection of the sequentially transferred data is, in part, dependent on the
`
`progressive translation of the three-dimensional viewpoint as dynamically
`
`modified on the client system during the transfer process. This achieves the
`
`above-stated objective while concurrently achieving a good rendering quality for
`
`continuous fly-over of the image as fast as possible, yet continuously building the
`
`image quality to the highest resolution of the image as stored by the server.
`
`To optimize image quality build-up over
`
`limited and narrowband
`
`communication links, the target image, as requested by the client system,
`
`is
`
`represented by multiple grids of 64x64 image pixels (Figure 4) with each grid
`
`having some corresponding level of detail. That is, each grid is treated as a
`
`sparse data array that can be progressively revised to increase the resolution of

`
`the grid and thereby the level of detail presented by the grid. The reason for
`
`choosing the 64x64 pixel dimension is that, using current image compression
`
`algorithms, a 16-bit 64x64 pixel array image can be presented as a 2KByte data
`
`parcel.
`
`In turn, this 2KByte parcel is the optimal size, subject to conventional
`
`protocol and overhead requirements, to be transmitted through a 3KByte per
`
`second narrowband transmission channel. Using a smaller image array, such ds
`
`32x32, would create a 0.5KByte parcel, hence ca using inefficiencies due to packet
`
`transmission overhead, given the nature of current wireless communications
`
`protocols.
`
`Image array dimensions are preferably powers of two so that they can be
`
`used in texture mapping efficiently. Each parcel, as received by the client system,
`
`is preferably immediately processed and incorporated into the presented image.
`
`To do so efficiently, according to the present invention, each data parcel
`
`is
`
`independently processable by the client system, which is enabled by the selection
`
`and server-side processing used to prepare a parcel for transmission. In addition,
`
`each data parcel is sized appropriate to fit within the level-l cache, or equivalent,
`
`of the client system processor, thereby enable the data processing intensive
`
`operations needed to process the data parcel to be performed without extended
`
`memory access delays.
`
`In the preferred embodiment of the present invention,
`
`data parcels are also processed for texture mapping and other image features,
`
`such as topographical detailing.
`
`Currently, with regard to conventional client systems, a larger image array,
`
`such as 128x128, is too large to be fully placed within the level-l cache of many
`
`of the smaller conventional current processors, such as used by personal digital

`
`substantially faster than to RAM this will likely result in lower frame rate.
`
`Different and larger data parcel sizes may be optimal as transmission
`
`protocols and micro-architectures of the client computers change. For purposes
`
`above, the data content was a pixel array representing image data. Where the
`
`data parcel content is vector, text or other data that may subiect to different client
`
`system design factors, other parcel sizes may be used.
`
`In the process implemented by the present invention, data parcels maybe
`
`selected for sequential transmission based on a prioritization of the importance
`
`of the data contained. The criteria of importance maybe defined as suitable for
`
`particular applications and may directly relate to the presentation of image
`
`quality, provision of a textual overlay of a low-quality image to quickly provide a
`
`navigational orientation, or the addition of topography information at a rate or
`
`timing different from the rate of image quality improvement. Thus, image data
`
`layers reflecting navigational cues,
`
`text overlays, and topography can be
`
`composed into data packets for transmission subiect to prioritizations set by the
`
`server alone, based on the nature and type of the client system, and interactively
`
`influenced by the actions and commands provided by the user of the client system
`
`(Figure 5).
`
`Progressive transmission of image parcels is performed in an iterative
`
`process involving selection of an image data grid within the target image of the
`
`client system, which is a portion of a potentially multi-layered source image stored
`
`by the server. The selection parameters are preferably dependent on the client
`
`navigation viewpoint, effective velocity, and height, and the effective level of detail
`
`currently presented in each grid. Once a grid is selected, the server selects the

`source data to be logically composed into the selected grid to complement the
`
`effective resolution of that grid, processing the grid data to produce the optimally
`sized size grid data parcels, and sequentially transmitting the parcels to the client
`
`system. Preferably, the detail of a grid array is sequentially enhanced by division
`
`of the grid into sub-grids related by a power of two (Figure 6). Thus, a given grid
`is preferably updated using four data parcels having twice the data resolution of
`
`the existing grid. Whatever number of parcels are used, each data parcel is
`rendered by the client system into the target image. Additional client system
`image data processing to provide texturing and three-dimensional representation
`
`of the data may be performed as part of the parcel rendering and integration into
`
`the target image.
`
`Image Parcel Download Seguence:
`
`The server of the present invention supports the download of parcel data
`
`to a client system by providing data parcels in response to network requests
`originated by client systems. Each requested data parcel is identified within a grid
`coordinate system relative to an image stored by the server.
`
`A client system implementing the process of the present invention is
`
`responsible for identifying and requesting parcel data, then rendering the parcel
`data into the target image at the correct location. The client system is also
`
`responsible for managing navigational and other interaction with the user.
`
`In
`
`identifying the parcel data to be requested, the client system operates to select
`
`grids within the coordinate system, corresponding to portions of the target image,
`for which to request a corresponding data parcel. The requests are issued over
`
`the network to the server and rendering performed asynchronously as data

`
`parcels are received. The order of data parcel requests is defined as a sequence
`
`that will provide for the optimal build-up of the target image as presented to the
`
`user. The rate of optimal build up of the target image is dependent on the nature
`
`of the target image requested, such as the supported parcel size and depth of the
`
`target image that can be rendered by the client system.
`
`The client identifies and requests the download of data parcels in the
`
`process as follows. Denote the target image as 10 and its size in pixels as (X, Y).
`
`Let N be the smallest power of 2 that is equal or greater than max {X,Y]-.
`
`Construct the grid of 64x64 pixel grid-images 101i,i that together compose the
`target image IO. The rectangle [64i,64i + 64] x [641,64 1 + 64] of I0 is mapped
`
`to 10,113.
`
`In order to view a large portion of the image, the target image, without
`
`downloading the substantial bulk of the target image, mip-maps of 10 are created,
`
`representing a collection of images to be used as surface textures when rendering
`
`a two-dimensional representation of a three-dimensional scene, and which are
`
`defined recursively as:
`
`1k+1 (1,1) = avg(lk (21,21), 1,421 + 1,21), 1421,21 + 1), lk(2i + 1,21+ 1))
`
`Such mip-maps are created up to IM,M = log2 (N) - 6. At this point, lM is
`a 64x64 image containing the entire area of the original image, hence no further
`
`mip-mapping is required.
`
`The methods of the present invention then proceed by constructing the
`respective grids or cells UK“) for each mip-map. Each nonempty image cell lkli'i
`now may be downloaded. Larger values of k cover more area within the original

`
`The principle mip-map level of an image cell is determined by the screen
`
`resolution, FOV (field of view) angle, the angle formed between the image's plane
`
`normal and the line connecting between the camera and the position within the
`
`cell that is closest to the camera, and a few other factors. The equation, which
`
`uses the above information, approximates the general mip-mapping level
`
`equation:
`
`l = max(0, log4 (T/S))
`
`in which 5 is the surface of the cell as displayed on the screen during rendering
`
`(in pixels), and T is the surface of the cell within the texture being mapped (in
`
`pixels).

`When rendering a cell of the grid lk,

`
`connecting the viewpoint and the point in the cell of shortest distance to it, t is the
`
`length of the square each pixel in the original image is assigned to in 3D, and z
`
`is the height of the camera over the image‘s plane.
`
`This arrives at the equation:

`
`Image Quality Management at T-Junctions:
`
`Note that the geometry (polygons) generated by quadtree scheme is non—
`
`manifold, dueto a problem shared among all adaptively subdivision triangulation
`
`schemes, known as the T-iunction cracking problem, where an image parcel is
`
`adiacent to two smaller image parcels.
`
`In the case of the present invention, all
`
`parcels are 64x64 pixel arrays, where the parcels for smaller dimensioned grids
`
`represent a correspondingly higher resolution. The spatial discontinuity created
`
`by the difference in resolutions, specifically between one grid and the sub-grids
`
`of an adjacent grid, results in undesirable display artifacts.
`
`The present invention provides a solution to this problem by converting the
`
`polygon, or in the present instance, grid mesh into a Manifold surface by adding
`
`vertices along edges connecting grids of different cell levels. The addition of new
`
`vertices, where necessary, is done efficiently, involving only constant time per
`
`vertex added.

`
`The algorithm of the present invention works as follows: an 8-bit square
`
`map is created, in which the edge length is 2 + N/64. Where the target image
`
`size in pixels is (X, Y), N is the smallest power of 2 that is equal or greater than
`
`max {X,Y}. For each frame rendered, the contents of this map are reset to zero.
`
`Each cell that is rendered, is also drawn as a square on the map, corresponding
`
`to the area it occupies, using the number M - l as a color, where l is the level of
`
`the grid the polygon is upon, where M is M = log2 (N) - 6.
`
`The boundaries of the map remain set to zero while the cells are drawn.
`
`When each of the polygons is rendered, its boundaries on the map are checked.
`
`Pixels on the map are evaluated to check if any vertices should be added.
`
`Locations that can be predicted mathematically are not read from the map and
`
`are skipped. Consequently, the process implemented by the present invention is
`
`efficient and, in particular, more efficient than searching within traditional data
`
`structures such as the Quad-tree as an approach to preventing the occurrence of
`
`T-iunction based artifacts.
