The application receives an interaction with the surface of the physical object, and based on the interaction, selects one or more virtual elements.

Abstract: An advertisement delivery system 1 includes an information manager, a timing information retriever, a selection determiner, and a selection handling processor. When switching between images displayed in a partial area on a web page is performed, the information manager keeps information about a pre-switching image even after the switching. The timing information retriever retrieves the timing of the switching and the timing of a selection operation by a user on the area. When the timing information retriever retrieves the timing of the selection operation within a predetermined time length after the switching, the selection determiner makes a determination as to which of the pre-switching image and a post-switching image the selection operation is intended for. Based on the determination, the selection handling processor performs a selection handling process based on information about the pre-switching image or the post-switching image.

Delineating a region may include receiving user input that delineates the region, and the input may trace a perimeter of the region. Delineating a region may include detecting an object and determining a perimeter of the detected object. The detected object may be classified as corresponding to a specified object type. The 2D image may include a camera perspective view of an object in the virtual reality environment.

Abstract: An aspect of the present invention clips a sequence of data values within a known range (defined by a set of integer values) by a ceiling value and a floor value. In an embodiment, such a feature is obtained by first storing in each of a sequence of memory locations a respective value corresponding to each integer value, with a stored value in a memory location equaling the floor value if the memory location corresponds to an integer having a value less than the floor value, equaling the ceiling value if the memory location corresponds to an integer having a value greater than the ceiling value, and equaling the value of the corresponding integer otherwise. When a sequence of data values are thereafter received for clipping, the clipped value for each data value is obtained by merely retrieving a corresponding stored value from the corresponding location.

Abstract: Some embodiments provide a method for editing an image. For a displayed image, the method draws a partial boundary based on movement of a cursor over the image. The partial boundary does not fully divide the image into a region of interest and a second region. Upon completion of the cursor movement, the method automatically extends at least one end of the boundary in order to divide the image into the region of interest and the second region. The method applies edits (e.g., color correction) to only the region of interest of the image. In some embodiments, automatically extending at least one end of the boundary involves (i) extending one or both of the ends to points at which the boundary ends intersect borders of the image and (ii) connecting the boundary from the intersection points along the borders of the image.

Abstract: A method and system for framework clipping are disclosed. A user interface tree of widgets corresponding to widgets requiring clipping is traversed. For each encountered widget, layer allocation operations are performed which include selecting a current, previous, or next layer to which to allocate the widget and determining whether the selected layer can accommodate the widget, where a determination that the selected layer cannot accommodate the widget results in a bit from a stencil buffer being allocated to the selected layer. A value of the selected layer is incremented to account for the widget being allocated to the selected layer A stencil test mask is generated as a combination of value of the layers previous to a current layer. The stencil test mask is written to the stencil buffer, and the layer allocation operations are repeated for each remaining widget.

Abstract: Modification of a model in situations, where one end of several parts should be transferred for the same distance, for instance, has posed a problem in modeling systems. The problem can be solved by defining a magnetic control plane to which model part handles locating thereon will adhere without separate definitions given by the user and they move (406) along with the plane. The only thing the user needs to do is to create a plane and to define the plane type to be a magnetic control plane. On the basis of these data given by the user the modeling system knows what to transfer when the magnetic control plane is transferred.

Abstract: A set of buffers is made available on a system-wide basis to provide capabilities for robust presentation of windows. The buffers can include a frame buffer, a system off-screen buffer and a compositing buffer. Windows are analyzed to determine and implement the most time-and memory-efficient use of the available buffers to properly display the intended result. In some situations, applications write directly to the frame buffer. Clipping can be used to prevent occluded portions of windows from being displayed. In other situations, some data is written to the off-screen buffer and/or to one or more application buffers, and the compositing buffer is used to perform compositing operations. Thus, a device can provide a wide range of display capabilities, including window compositing, while minimizing costs in terms of memory usage and processing power. Such advantages are of particular use in mobile devices and other systems having limited resources.

Views of network components may be filtered so only components pertaining to a specific business or other interest are displayed.

Abstract: A cursor mode display system and method for indicating an offset distance between a cursor position on an image and a closest image slice in a corresponding image series. First, the three-dimensional coordinates associated with the cursor position on the image are determined by projecting the cursor position onto a three-dimensional patient coordinate system. The closest image slice is then identified as the image slice in the corresponding image series that is closest to the three-dimensional coordinates of the cursor position. The offset distance between the closest image slice and the three-dimensional coordinates associated with the cursor position is then calculated. If the offset distance does not exceed a threshold value, then the closest image slice is displayed. Otherwise a modified version of the closest image slice is displayed.

Abstract: A method and computer-readable medium are provided for generating graphics having a finite number of dynamically sized and positioned shapes. According to the method, a relative size and position are defined for each of the shapes in a graphic. The relative size and position of the shapes may be defined relative to a canvas size or relative to other shapes. Once the size and position have been defined, the size and position are translated into size and position values expressed as relative to a canvas size. A mapping is also created between specific locations in a data set and the shapes. The graphic is generated utilizing the mapping and by sizing and positioning the shapes relative to the current canvas size. If a new canvas size is detected, the size and position of the shapes may be recomputed relative to the new canvas size. The graphic may also be utilized within a dynamic graphic.

Abstract: The effective illumination volume (e.g., angular spread and falloff) of each light source in an object model scene can be represented by a simple geometry. Geometry-based culling techniques then can be used to automatically remove or de-activate lights for a frame, set of frames, or entire shot of animation, based on interactions of the light geometries with objects in the scene. The light pruning process can be run in a pre-pass procedure, such that production and rendering preparation procedures do not have to deal with lights that will not affect a final image. Further, a pre-pass pruning removes lights before rendering, such that the data for each light does not have to be loaded into memory at render time. Removing the lights before rendering also can reduce a amount of ray tracing and other processing used for the lights at render time.

In one embodiment, the RA module performs clipping by way of conducting the rendering step of the rasterization process. This approach distributes the complexity in the graphics processing pipeline and makes the design simpler and faster, therefore design complexity, cost and performance may all be improved in hardware implementation.
