Implementations

impl OcclusionCuller

pub fn new(width: u32, height: u32) -> Self

pub fn is_occluded_hiz( &self, aabb_min_uv: Vec2, aabb_max_uv: Vec2, nearest_depth: f32, hi_z_mips: &[Vec<f32>], ) -> bool

Test whether a screen-space AABB (in UV space) is occluded given a conservative min-depth estimate for the bounding box.

pub fn build_hi_z_pyramid( depth_buffer: &[f32], width: u32, height: u32, ) -> Vec<Vec<f32>>

Build hi-z pyramid from a full-res depth buffer (conservative: max depth per 2x2 block)
