摘要： In some embodiments, tile lists may be avoided by storing the geometry of a scene in a bounding volume hierarchy (BVH). For each tile, the bounding volume hierarchy is traversed. The traversals continued only into children nodes that overlap with the frustum on the tile. By relaxing the ordering constraint of rendering primitives, the BVH is traversed such that nodes that are closer to the viewer are traversed first, increasing the occlusion culling efficiency in some embodiments. Rendering the full scene between the central processing cores and the graphics processor may be done through a shared memory in some embodiments.

摘要： A rasterizer, based on time-dependent edge equations, computes analytical visibility in order to render accurate motion blur. An oracle-based compression algorithm for the time intervals lowers the frame buffer requirements. High quality motion blurred scenes can be rendered using a rasterizer with rather low memory requirements. The resulting images may contain motion blur for both opaque and transparent objects.

摘要： The time needed for back-end work can be estimated without actually doing the back-end work. Front-end counters record information for a cost model and heuristics may be used for when to split a tile and ordering work dispatch for cores. A special rasterizer discards triangles and fragments outside a sub-tile.

摘要： In order to efficiently backface cull rendering primitives during computer graphics rendering, it is important to be sure that the rendering primitives to be culled are guaranteed to be backfacing even if the primitives are moving or are undergoing defocus blur. Therefore, we derive conservative tests that determine if a moving and defocused triangle is backfacing over an entire time interval and over the area of a lens. In addition, we present tests for the special cases of only motion blur and only depth of field.

摘要： Micropolygon splatting may involve tessellating by subdividing a mesh until triangle edges are shorter than 0.75 pixels. In some cases, rasterizing the primitive may be avoided.

摘要： Motion blur rasterization may involve executing a first test for each plane of a tile frustum. The first test is a frustum plane versus moving bounding box overlap test where planes bounding a moving primitive are overlap tested against a screen tile frustum. According to a second test executed after the first test, for primitive edges against tile corners, the second test is a tile corner versus moving edge overlap test. The corners of the screen space tile are tested against a moving triangle edge in two-dimensional homogeneous space.

摘要： A standard occlusion query (OQ) may be generalized to five dimensions, which can be used for motion blurred, defocused, occlusion culling. As such, the occlusion query concept is generalized so that it can be used within 5D rasterization, which is used for rendering of motion blur and depth of field. For 5D rasterization, occlusion culling may be done with OQs as well, applied to solve other rendering related problems.
