Struct PointCloudDecoder 

pub struct PointCloudDecoder { /* private fields */ }

Available on crate feature decoder only.

Decoder for Draco point cloud bitstreams.

PointCloudDecoder reads a point-cloud .drc bitstream and reconstructs a PointCloud with its attributes and metadata. Both KD-tree and sequential attribute encodings are supported (the actual decode requires the point_cloud_decode feature).

A round trip is shown on the PointCloudEncoder type docs.

Implementations

impl PointCloudDecoder

pub fn new() -> Self

Creates a point cloud decoder with default state.

pub fn decode( &mut self, in_buffer: &mut DecoderBuffer<'_>, out_pc: &mut PointCloud, ) -> Status

Available on crate feature point_cloud_decode only.

Decodes a Draco point cloud from in_buffer into out_pc.

Errors

Returns an error if the header is invalid, the bitstream version is unsupported, or the encoded attributes are malformed.

pub fn decode_after_header( &mut self, version_major: u8, version_minor: u8, method: u8, buffer: &mut DecoderBuffer<'_>, out_pc: &mut PointCloud, ) -> Status

Available on crate feature point_cloud_decode only.

Decode point cloud data when header + metadata have already been parsed. Used by MeshDecoder to delegate point cloud streams.

pub fn get_geometry_type(&self) -> EncodedGeometryType

Returns the encoded geometry type handled by this decoder.

Trait Implementations

impl Default for PointCloudDecoder

fn default() -> Self

Returns the “default value” for a type.

impl GeometryDecoder for PointCloudDecoder

fn point_cloud(&self) -> Option<&PointCloud>

Returns point-cloud geometry when available.

fn mesh(&self) -> Option<&Mesh>

Returns mesh geometry when available.

fn corner_table(&self) -> Option<&CornerTable>

Returns mesh corner-table topology when available.

fn get_geometry_type(&self) -> EncodedGeometryType

Returns the encoded geometry type.

fn get_attribute_encoding_method(&self, _att_id: i32) -> Option<i32>

Returns the attribute encoding method for an attribute id, if known.
