Abstract: A hierarchical acceleration structure for use in a ray tracing system. When generating a node for the hierarchical acceleration structure, the primitives in a particular portion of the 3D scene may be alternatively bounded by different shaped volumes. These bounding volumes or ‘bounding regions’ can be Axis Aligned Bounding Boxes (AABBs), although other bounding volumes can be used. The ray tracing system may use sets of two or more bounding volumes in a 3D scene to bound all the primitives within that portion. The choice of how to create sets of multiple bounding volumes within a portion of the 3D scene may be done by using a binary space partition (BSP). Different sets of bounding regions may present different amounts of surface area for a hypothetical ray entering the portion of the 3D scene dependent upon the expected ray direction or angle.

Abstract: Technology is disclosed herein for integrating native and non-native dependencies in a spreadsheet hosted by a spreadsheet application. In an implementation, a computing apparatus identifies a formula in a first cell of a spreadsheet which includes a non-native argument. The computing apparatus identifies a dependency between the first cell and a second cell created by the non-native argument. The computing apparatus limits recalculations of the spreadsheet based at least on the dependency. In an implementation, absent any other dependencies between the first cell and other cells, the first cell is excluded from recalculations triggered by changes to the other cells and included in recalculations triggered by the second cell. In an implementation, a direct or indirect dependency is created by, respectively, an explicit or implicit reference to the second cell in the non-native argument. In some implementations, the formula is native to the spreadsheet application hosting the spreadsheet.
