摘要： A hierarchical structure for accelerating ray tracing operations in scene rendering includes a plurality of geometry objects, and a single acceleration structure constructed over the collective plurality of geometry objects. Each geometry object includes primitives of a predefined type, whereby primitives within the plurality of geometry objects collectively define a geometry included within a region of the scene which is to be rendered. The single acceleration structure is operable for accelerating ray tracing operations for the primitives included within the plurality of geometry objects, and is constructed over the plurality of the geometry objects without an intervening bounding volume representation of the plurality of primitives included within the geometry objects.
摘要翻译：用于在场景渲染中加速光线跟踪操作的层次结构包括多个几何对象，以及在集合的多个几何对象上构造的单个加速度结构。每个几何对象包括预定义类型的原语，由此多个几何对象内的图元共同地定义了包含在将被渲染的场景的区域内的几何形状。单个加速结构可操作用于加速包括在多个几何对象内的图元的光线跟踪操作，并且被构造在多个几何对象上，而不包括在几何对象内的多个图元的中间的边界体积表示。

摘要： A system, method, and computer program product are provided for constructing a hierarchical acceleration data structure that supports ray tracing of motion blur. In use, scene description data associated with an image to be generated is received. Additionally, a hierarchical acceleration data structure for performing ray tracing on the scene description data is constructed, where the hierarchical acceleration data structure supports ray tracing of motion blur.

摘要： The disclosure is directed to a method for communicating with a monitoring device. The method includes sending an unsolicited-type message from a client program resident on the monitoring device coupled to a first secure network. The unsolicited-type message is sent to a computing system coupled to a second network separated from the first secure network by a firewall. The method also includes receiving a response message to the unsolicited-type message from the computing system. The response message includes an embedded unsolicited-type message. The client program is resident on the monitoring device receiving the response message. The method further includes providing the embedded unsolicited-type message to a server program resident on the monitoring device.

摘要： A system and method for constructing a bounding volume hierarchical structure are disclosed. The method includes defining a parent node for the bounding volume hierarchical structure, the parent node including a parent node bounding volume enclosing a plurality of objects. A first cost is computed for performing an object partition of the parent node bounding volume to produce a first plurality of child node bounding volumes, and a second cost is also computed for performing a spatial partitioning of the parent node bounding volume to produce a second plurality of child node bounding volumes. The bounding volume hierarchical structure is constructed employing the second plurality of child node bounding volumes produced from the spatial partitioning of the parent node bounding volume if the second cost is lower than the first cost.
