Google Filament Real-Time Post-Processing Pipeline
Hardware-accelerated cinematic rendering pipeline featuring Hierarchical Z-Buffer depth pyramids, HDR multi-pass Bloom, and raymarched volumetric light shafts.
HZB Pipeline Controls & Occlusion Culling
Google Filament HZB Architecture Specification
Why is HZB (Hierarchical Z-Buffer) so efficient?
1. Single-Pass 2x2 Min/Max Downsampling: HZB generates a 5-level mip pyramid directly on the tile cache in a fraction of a millisecond (<0.06 ms).
2. Conservative Occlusion Culling: Before dispatching expensive fragment shaders on occluded objects (such as pillars behind walls), the bounding box is tested against the lowest fitting HZB mip. If the box is behind the HZB depth value, the entire draw call is rejected immediately.
3. Hi-Z Empty Space Skipping: Screen-space reflections jump multiple pixels per step by querying higher mip levels when raymarching empty air, reducing ray samples from 64 down to 8!
