An apparatus and method for reconstructing a skeletal image for osteoporotic diagnosis is disclosed. A skeletal image reconstruction method may include separating a region of interest (ROI) corresponding to a skeletal system from an image captured from an inspection target, and reconstructing a high-resolution skeletal image by performing a finite element method (FEM) and topology optimization on the ROI.

A method for authoring and displaying a virtual tour of a three-dimensional space which employs transitional effects simulating motion. An authoring tool is provided for interactively defining a series of locations in the space for which two-dimensional images, e.g., panoramas, photographs, etc., are available. A user identifies one or more view directions for a first-person perspective viewer for each location. For pairs of locations in the series, transitional effects are identified to simulate smooth motion between the pair of locations. The authoring tool stores data corresponding to the locations, view directions and transitional effects for playback on a display. When the stored data is accessed, a virtual tour of the space is created that includes transitional effects simulating motion between locations. The virtual tour created can allow a viewer to experience the three-dimensional space in a realistic manner.

Embodiments of the present invention provide a novel system and/or method for performing over-the-network collaborations and interactions between remote end-users. Embodiments of the present invention produce the perceived effect of each user sharing a same physical workspace while each person is actually located in separate physical environments. In this manner, embodiments of the present invention allow for more seamless interactions between users while relieving them of the burden of using common computer peripheral devices such as mice, keyboards, and other hardware often used to perform such interactions.

Methods, systems, and apparatus, including computer program products feature providing a rendering of a three-dimensional assembly of components. An explosion sequence for separating first components of the assembly is determined. The explosion sequence comprises stages in which each stage represents a different spatial relationship between two or more of the first components. A first input is received from an interactive control. A first stage in the explosion sequence is selected based on the first input. The rendering of the assembly is updated, responsive to the first input, to show the first stage of the explosion sequence. A second input is received from the interactive control. A different second stage in the explosion sequence is selected based on the second input. The rendering of the assembly is updated, responsive to the second input, to show the second stage of the explosion sequence.
摘要:
A system and method for visualizing a 3D scene using a flexible display are disclosed. The 3D scene reflects a model of graphics objects, where each graphics object is represented by 3D primitives such as vertices, lines, or surfaces. A display processor generates a 2D image of the 3D scene using various graphics rendering techniques such as non-linear ray-tracing algorithms. A sensor associated with the flexible display detects that a surface profile of the display has been altered, which causes the display processor to generate a new 2D image of the 3D scene. The effect is that flexing the display allows the user to view the 3D scene from a different perspective. In one embodiment, the different perspective is viewing the object from a different camera position. In another embodiment, the different perspective is provided by generating an exploded view of an assembly of graphics objects.
摘要:
A portable electronic device (e.g., smart phone or tablet computer) is provided for generating and displaying images (e.g., 2-dimensional or 3-dimensional images) of an imaging target such as a human body. The portable electronic device may include imaging elements configured to receive radiation signals transmitted through and/or reflected by the imaging target, an imaging interface, and one or more processors. The portable electronic device may display what appears to be a window into the imaging target (e.g., a human body), and/or an exploded view (e.g., 3-dimensional, upwardly projected image) of the target. The generated image may be a real-time continuous image of the internal features of the target (e.g., a human body) that is updated to track movements of the target (e.g., breathing patterns) and the relative position of the portable electronic device as the portable electronic device moves relative to a surface of the target.
摘要:
A digital map of a geographic area is displayed via a user interface, and a 3D representation of a multi-story building located in the geographic area is displayed on the digital map. The 3D representation includes multiple stacked floor maps corresponding to the floors of the multi-story building. In response to the detection of a pinch gesture that is applied to the 3D representation, a vertical distance between each floor map is expanded relative to the detected pinch gesture to reveal features of an internal map that corresponds to each floor map.

In response to user selection of automatic generation of an exploded view of a data element at a level in a hierarchical representation of an assembly, an exploded view of at least part of the assembly at the selected level can be generated automatically and the exploded view presented to the user.
