摘要： A method for rendering a deformable object. The method includes: obtaining a 3D volumetric voxel dataset of a region, such region having therein an object to be rendered; building a tree hierarchical structure for the obtained volumetric dataset, such tree structure blocks as the nodes of a primary tree hierarchy and bricks being those blocks stored as textures in a video memory; augmenting the primary tree hierarchical structure with maximum and minimum values of the data contained within a block; creating a neighborhood tree hierarchy having for each leaf block of the neighborhood tree hierarchy a reference to the neighboring leaf blocks in the neighborhood tree hierarchy as well as references to neighboring bricks in the neighborhood tree hierarchy; updating the information about minimum and maximum in the primary tree hierarchy by saving for each block the minimum and maximum of the neighboring blocks; and rendering the leaf blocks in visibility order.

摘要： According to one embodiment, techniques are provided to enable secure communication among devices in a mesh network using a group temporal key. An authenticator device associated with a mesh network stores a pairwise master key for each of a plurality of devices in a mesh network upon authentication of the respective devices. Using the pairwise master key, the authenticator device initiates a handshake procedure with a particular device in the mesh network to mutually derive a pairwise temporal key from the pairwise master key. The authenticator device encrypts and signs a group temporal key using the pairwise temporal key for the particular device and sends the group temporal key encrypted and signed with the pairwise temporal key to the particular device.

摘要： Described herein is a system and method for facilitating large volume data processing and rendering. An exemplary system includes at least one processor coupled to a first memory, wherein the processor is configured to organize the large volume data in the first memory into one or more bricks. In addition, at least one graphics processing unit (GPU) is coupled to the processor and a second memory. The GPU is configured to process at least one or more bricks transferred from the first memory to the second memory to produce intermediate processing results, and to further render the intermediate processing results.
