Abstract:
Methods and apparatus relating to more efficient ray tracing of instanced geometry are described. In an embodiment, overlapping instances are unbraided, by not instantiating the entire objects, but instantiating multiple sub-BVH nodes of the objects, which improves rendering performance by reducing overlap of BVH nodes. Other embodiments are also disclosed and claimed.

Claim (Index 15):
A method comprising:\n storing information corresponding to a two-level Bounding Volume Hierarchy (BVH) structure in memory; and building and traversing, at a processor, the two-level BVH structure over instanced geometries, wherein each leaf node of a top-level of the two-level BVH structure stores a transformation and a reference to a node of a geometry BVH, wherein one or more nodes are added to the BVH structure, wherein the one or more nodes are capable to directly point to one or more locations of an instanced object to allow for a more efficient traversal of the BVH structure, wherein the processor performs an operation to reduce spatial overlap in a list of instanced BVH nodes by repeatedly replacing one or more instanced nodes with an instancing of their child nodes until some termination criteria is fulfilled, wherein the processor performs the operation as a preprocessing pass to generate the list of instanced BVH nodes as input to a BVH building procedure.
