Abstract: An apparatus and method for efficiently reconstructing a BVH. For example, one embodiment of a method comprises: constructing an object bounding volume hierarchy (BVH) for each object in a scene, each object BVH including a root node and one or more child nodes based on primitives included in each object; constructing a top-level BVH using the root nodes of the individual object BVHs; performing an analysis of the top-level BVH to determine whether the top-level BVH comprises a sufficiently efficient arrangement of nodes within its hierarchy; and reconstructing at least a portion of the top-level BVH if a more efficient arrangement of nodes exists, wherein reconstructing comprises rebuilding the portion of the top-level BVH until one or more stopping criteria have been met, the stopping criteria defined to prevent an entire rebuilding of the top-level BVH.

Abstract: An embodiment of an electronic processing system may include an application processor, persistent storage media communicatively coupled to the application processor, a graphics subsystem communicatively coupled to the application processor, a sense engine communicatively coupled to the graphics subsystem to provide sensed information, a focus engine communicatively coupled to the sense engine and the graphics subsystem to provide focus information, a motion engine communicatively coupled to the sense engine, the focus engine, and the graphics subsystem to provide motion information, and a motion biased foveated renderer communicatively coupled to the motion engine, the focus engine, the sense engine to adjust one or more parameters of the graphics subsystem based on one or more of the sense information, the focus information, and the motion information. Other embodiments are disclosed and claimed.
