Struct GpuBvhBuilder 

pub struct GpuBvhBuilder { /* private fields */ }

Builds a flat BVH from a list of AABBs using Morton-code sorting.

The builder sorts primitives by their Morton code (computed from the centroid of each AABB), then constructs the BVH bottom-up.

Implementations

impl GpuBvhBuilder

pub fn new() -> Self

Create a new, empty GpuBvhBuilder.

pub fn build(&mut self, aabbs: &[AabbGpu]) -> usize

Build a BVH from a slice of AabbGpu primitives.

Returns the index of the root node in the returned flat node array.

pub fn nodes(&self) -> &[BvhNodeGpu]

Return a reference to the built flat node array.

pub fn query_overlaps(&self, root: usize, query: &AabbGpu) -> Vec<u32>

Query all leaf primitives whose AABB overlaps query.

impl Default for GpuBvhBuilder

fn default() -> GpuBvhBuilder
