A data model of a modeled environment is maintained within a database. The data model includes data defining a plurality of hierarchically arranged subsets of space within the modeled environment and data defining a plurality of items populating the modeled environment. A data processing system displays within a display device at least first and second windows. The first window displays a map of the modeled environment, where the map includes at least one user-selectable graphical element representing one of the plurality of hierarchically arranged subsets of space or one of the plurality of items. In response to a first user input, a graphical element is copied from the first window and displayed within the second window. In response to a second user input selecting the graphical element within the second window, data from the database associated with the subset of space or item represented by the graphical element is presented.

A system and method for drawing in a three-dimensional space. The drawings may include dots, line segments, arrows, polylines (open and closed), polygons, surfaces and 3D volumes. The method may include receiving user input that specifies a drawing in a displayed window and mapping the drawing into the 3D space. The mapping process may involve mapping the drawing onto a surface of an existing graphical object in the 3D space, or, mapping the drawing onto a user-specified plane in the 3D space. The drawing may represent a user's interpretation of a geological feature present on the graphical object surface. The graphical object may represent an object of significance in hydrocarbon exploration and production, e.g., an interpreted section or horizon in the earth's subsurface.

Methods and systems for compressing and decompressing 3-D geometry data which includes regularly tiled surface portions. One compression method includes representing a surface portion as a "vertex raster", which comprises specifying an extent value and encoding the vertex parameter values of vertices within the surface portion. The extent of the surface portion specifies the arrangement of vertices within the surface portion, and allows the vertices to be properly assembled into drawing primitives during decompression. The encoded vertex parameter values may be encoded globally (by setting initial values and corresponding delta values), locally (on a per-vertex basis), or using a combination of these techniques. Absolute, delta encoding, or delta-delta encoding may be utilized for these parameter values. Vertex parameters which may be encoded in this manner include position, color, normals, z-displacement values, texture map coordinates, and surface material properties. Additionally, connectivity information may also be encoded using this compression method by specifying quad split bits and half-resolution edges. Quad split bits are used to tessellate a quadrilateral formed by neighboring vertices of a surface portion according to the direction of the strongest color change. Half-resolution edges are utilized to gradually shift from an area of high resolution to an adjacent surface portion represented in lower resolution. For graphical objects which include a plurality of adjacent surface portions, a step command is disclosed which allows data from one surface portion to be advantageously reused. Decompression of a vertex raster representation may comprise decoding the extent value, global parameter values, and a per-vertex stream of local parameter values.

A system, apparatus, and method are disclosed for modifying positions of sample positions for selectably oversampling pixels to anti-alias non-geometric portions of computer-generated images, such as texture, at least in part, by shifting shading sample positions relative to a frame of reference. There is generally no relative motion between the geometries and the coverage sample positions. In one embodiment, an apparatus, such as a graphics pipeline and / or a general purpose graphics processing unit, anti-aliases geometries of a computer-generated object. The apparatus includes at least a texture unit and a pipeline front end unit to determine geometry coverage and a subpixel shifter to shift shading sample positions relative to the frame of reference. The apparatus can receive subpixel shifting masks to select subsets of shading sample positions. Each of the shading sample positions is shifted to a coverage sample position to reduce level of detail (“LOD”) artifacts.

Systems, methods, and computer-readable media for manipulating graphical objects are provided. For example, a polygonal mesh may be modeled based on graphical object content, and then both a graphical object based on the graphical object content and a map of control points based on the polygonal mesh may be rendered on a display. A user may activate one or more of the displayed control points and may provide one or more user movements to reposition the activated control points. The polygonal mesh may be physically simulated in response to the user movements of the control points, and then the graphical object and the map of control points may be re-rendered based on the physical simulation of the polygonal mesh. The graphical object content may include multiple character glyphs of a text string, and the polygonal mesh for that content may include one or more intra-character polygons per character glyph.

A program and apparatus which draw and display images of graphical objects, enabling their smooth and continuous transition from visible state to invisible state. For each given object, its distance from the current eye point is calculated for comparison with a predetermined semi-transparent distance, as well as with a predetermined invisible distance which is longer than the semi-transparent distance. The object is selected as a visible object that is to be subjected to image drawing operations if the above comparison has revealed that the calculated distance is shorter than the invisible distance. An image of the visible object is drawn in opaque mode if the distance is shorter than the semi-transparent distance, or in semi-transparent mode if the distance is longer than the semi-transparent distance. The resultant image is then displayed on a monitor screen.

In a typical embodiment, when a user attempts to access a computerized device, the user will be presented with a plurality of graphical objects (e.g., icons, shortcuts, shapes, patterns, etc.). The user may then select a particular graphical object (e.g., via a touch screen) and perform one or more user interactions therewith. Such user interactions may include (but are not limited to) physical manipulations of the graphical object, and / or audio / video manipulations made in conjunction with the selection of the graphical object. The graphical object(s) selected and the user interaction performed will then be compared to previously stored authentication information to determine whether the access to the computerized device should be granted to the user.
