Struct VoxelGridDownsample 

pub struct VoxelGridDownsample { /* private fields */ }

Voxel-grid downsampling filter.

Implementations

impl VoxelGridDownsample

pub const fn new(config: VoxelGridDownsampleConfig) -> VoxelGridDownsample

Creates a filter from config.

pub const fn config(&self) -> VoxelGridDownsampleConfig

Returns the filter config.

pub fn filter_with_policy( &self, input: &PointCloud, policy: ExecutionPolicy, ) -> Result<PointCloud, SpatialError>

Applies the filter using the requested execution policy.

GPU execution assigns voxel keys on wgpu, builds segments with GPU sorting, and performs centroid or approximate-first aggregation on wgpu.

ExecutionPolicy::Auto picks GPU only when the input meets VoxelGridDownsampleConfig::gpu_min_points. Explicit GPU requests below the threshold fall back to CPU to avoid upload/readback overhead on small clouds.

Trait Implementations

impl Clone for VoxelGridDownsample

fn clone(&self) -> VoxelGridDownsample

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VoxelGridDownsample

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for VoxelGridDownsample

fn eq(&self, other: &VoxelGridDownsample) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PointCloudFilter for VoxelGridDownsample

fn name(&self) -> &'static str

Human-readable filter name.

fn filter(&self, input: &PointCloud) -> Result<PointCloud, SpatialError>

Applies the filter and returns a new point cloud.
