pub struct PickAccelerator { /* private fields */ }Expand description
BVH-accelerated picking structure with TriMesh cache.
Implementations§
Source§impl PickAccelerator
impl PickAccelerator
Sourcepub fn build_from_scene(
scene: &Scene,
mesh_aabb_fn: impl Fn(MeshId) -> Option<Aabb>,
) -> Self
pub fn build_from_scene( scene: &Scene, mesh_aabb_fn: impl Fn(MeshId) -> Option<Aabb>, ) -> Self
Build a BVH from the current scene state.
mesh_aabb_fn provides the local-space AABB for each mesh.
Sourcepub fn pick(
&mut self,
ray_origin: Vec3,
ray_dir: Vec3,
mesh_lookup: &HashMap<u64, (Vec<[f32; 3]>, Vec<u32>)>,
) -> Option<PickHit>
pub fn pick( &mut self, ray_origin: Vec3, ray_dir: Vec3, mesh_lookup: &HashMap<u64, (Vec<[f32; 3]>, Vec<u32>)>, ) -> Option<PickHit>
Pick the nearest object hit by the ray.
mesh_lookup maps mesh_index to (positions, indices) for TriMesh construction.
Sourcepub fn invalidate_mesh(&mut self, mesh_index: usize)
pub fn invalidate_mesh(&mut self, mesh_index: usize)
Invalidate the TriMesh cache for a specific mesh (e.g. after re-tessellation).
Sourcepub fn invalidate_all(&mut self)
pub fn invalidate_all(&mut self)
Clear all cached data. A full rebuild is needed.
Sourcepub fn trimesh_cache_len(&self) -> usize
pub fn trimesh_cache_len(&self) -> usize
Number of cached TriMesh instances.
