Formulating the visual scene also includes accessing a data series, which includes data points to be applied to the shapes. Formulating the visual scene also includes accessing a geometry, which includes a container, a binding definition, and an arrangement definition. The data series is visualized within the container by visually rendering each shape within the container. The binding definition defines how to apply each data point to a shape. The arrangement definition defines how to map an axis set to a coordinate system of the container, and how to lay out the shapes within dimensions of the container.

Abstract: Digitizing objects in a picture is discussed herein. A user presents the object to a camera, which captures the image comprising color and depth data for the front and back of the object. The object is recognized and digitized using color and depth data of the image. The user's client queries a server managing images uploaded by other users for virtual renditions of the object, as recognized in the other images. The virtual renditions from the other images are merged with the digitized version of the object in the image captured by the user to create a composite rendition of the object.

Abstract: A method, apparatus and system for, in a computing system, modeling a subsurface structure at a time period when the structure was originally formed. A memory may store a first model having a plurality of non-planar horizons representing a current state of the subsurface structure. A processor may compute a vector field based on the non-planar geometry of the horizons of the first model. The vector field may be a non-uniform vector field (e.g., the axe and/or co-axe vector field) or a uniform vector field (e.g., a global axis). Using the vector field, the processor may transform geographic coordinates of the first model to paleo-geographic coordinates of a second model representing a predicted state of the subsurface structure at a time period when the subsurface structure was originally formed, where the non-planar horizons in the first model are transformed to planar horizons in the second model. A display may display the first model.

Abstract: A three-dimensional (3D) image providing method and a display apparatus using the same are provided. According to the 3D image providing method, if a particular manipulation is input from a user in the two-dimensional (2D) mode, whether an input image is a 2D image or a 3D image is detected. If the input image is the 3D image, the display mode is changed to the 3D mode and the 3D image is displayed. If the input image is the 2D image, the input 2D image is converted to a 3D image and the converted 3D image is displayed by changing the display mode to the 3D mode. Thus, regardless of whether the input image is the 2D image or the 3D image, users can execute the 3D mode using the single manipulation.

Abstract: Generating computer models of 3D objects is described. In one example, depth images of an object captured by a substantially static depth camera are used to generate the model, which is stored in a memory device in a three-dimensional volume. Portions of the depth image determined to relate to the background are removed to leave a foreground depth image. The position and orientation of the object in the foreground depth image is tracked by comparison to a preceding depth image, and the foreground depth image is integrated into the volume by using the position and orientation to determine where to add data derived from the foreground depth image into the volume. In examples, the object is hand-rotated by a user before the depth camera. Hands that occlude the object are integrated out of the model as they do not move in sync with the object due to re-gripping.

Abstract: One or more systems, devices, and/or methods for illustrating depth are disclosed. For example, a method includes receiving a depthmap generated from an optical distancing system. The depthmap includes depth data for each of a plurality of points, which are correlated to pixels of an image. Data indicative of a location on the image is received. Depth data correlated with the first point is compared to depth data correlated with pixels at surrounding points in the image. If the depth data correlated with the first point indicate a lesser distance from a viewer perspective of the image than the depth data of a pixel at the surrounding points in the image, the pixel is changed to a predetermined value. The comparison may be repeated at other pixels and a depth illustration may be drawn that relates the depth of the received location to other objects in the image.
