Technical details and manufacturing context for Hierarchy Builder

Definition
The Hierarchy Builder is a specialized sub-component of the optional Hierarchical Z/Stencil Culling Unit (HZCU) in graphics processing systems. Its primary function is to dynamically generate and maintain a hierarchical representation (often a tree or pyramid structure) of depth or stencil values from the scene geometry. This hierarchy enables efficient traversal and testing during the occlusion culling process, allowing the HZCU to quickly identify and discard objects or pixels that are not visible, thereby reducing the computational load on the rendering pipeline.
Working Principle
The Hierarchy Builder operates by processing incoming depth or stencil data from the geometry pipeline. It typically aggregates this data into tiles or blocks at multiple levels of detail (e.g., from fine-grained pixel data to coarser region summaries). It constructs a data structure where parent nodes contain conservative depth bounds (like the farthest depth) of their child regions. This structure is built and updated in real-time, often using parallel hardware logic, to provide the HZCU with an efficient map for hierarchical occlusion queries.
