摘要:
Various embodiments are presented herein that may render an image frame on an autostereoscopic 3D display. A computer platform including a processor circuit executing a rendering application may determine a current orientation of a virtual camera array within a three-dimensional (3D) scene and at least on additional 3D imaging parameter for the 3D scene. The rendering application, with the aid of a ray tracing engine, may also determine a depth range for the 3D scene. The ray tracing engine may then facilitate rendering of the image frame representative of the 3D scene using a ray tracing process.

At least a first capacitor is formed on a substrate and connected to a first differential node of a differential circuit, and the first capacitor may be variable in capacitance. A second capacitor is formed on the substrate and connected to a second differential node of the differential circuit, and the second capacitor also may be variable. A third capacitor is connected between the first differential node and the second differential node, and is formed at least partially above the first capacitor. In this way, a size of the first capacitor and/or the second capacitor may be reduced on the substrate, and capacitances of the first and/or second capacitor(s) may be adjusted in response to a variable characteristic of one or more circuit components of the differential circuit.

A multi-core processor system may support 3D image rendering on an autostereoscopic display. The 3D image rendering includes pre-processing of depth map and 3D image wrapping tasks. The pre-processing of depth map may include a foreground prior depth image smoothing technique, which may perform a depth gradient detection and a smoothing task. The depth gradient detection task may detect areas with large depth gradient and the smoothing task may transform the large depth gradient into a linearly changing shape using low-strength, low-pass filtering techniques. The 3D image wrapping may include vectorizing the code for 3D image wrapping of row pixels using an efficient single instruction multiple data (SIMD) technique. After vectorizing, an API such as OpenMP may be used to parallelize the 3D image wrapping procedure. The 3D image wrapping using OpenMP may be performed on rows of the 3D image and on images of the multiple view images.

The present invention relates to a method for generating a reference signal, including: obtaining first control information, where the first control information indicates or includes cyclic shift related information which is used by a terminal belonging to a serving cell to send a reference signal; and sending the first control information to the terminal belonging to the serving cell, so that the terminal belonging to the serving cell generates the reference signal according to the cyclic shift related information which is indicated or included by the first control information and used by the terminal to send the reference signal, where a variation rule of a cyclic shift which the terminal belonging to the serving cell uses to generate the reference signal is the same as that of a cyclic shift which a terminal belonging to a coordinated cell uses to generate the reference signal.

Procedures and systems may be used for assigning data partitions to data-processing host computers, for example, to initially assign data partitions at the outset of a large data-processing job or during failover measures taken in response to a failed host in a share-nothing database management system (SN-DBMS). In one implementation, a method of managing exclusive access to a data partition within a database system assesses a first host and a second host that have exclusive access to a first and second data partition, respectively, within a database system. The method assigns exclusive access of the data partition to one of the first and second hosts based on factors that may include the processing powers of first and second the hosts, and on processing requirements (such as data quantity and data criticalness) for data on the first and second data partitions.

A magnetically actuated visual display board comprises a grid array of open ended chambers. Display configurations in each chamber utilize a magnetically responsive sliding element to move a display loop to alternate between two different display surfaces to create a desired visual array. A magnetic rod passing a chamber moves the sliding element within the chamber.
