Struct PointCloud 

pub struct PointCloud { /* private fields */ }

Point cloud geometry with typed attributes and optional metadata.

Implementations

impl PointCloud

pub fn new() -> Self

Creates an empty point cloud.

pub fn set_num_points(&mut self, num_points: usize)

Sets the number of logical points.

pub fn add_attribute(&mut self, attribute: PointAttribute) -> i32

Adds an attribute and assigns it a unique id matching its attribute id.

pub fn add_attribute_preserve_unique_id( &mut self, attribute: PointAttribute, ) -> i32

Adds an attribute while preserving its existing unique id.

pub fn set_attribute(&mut self, att_id: i32, attribute: PointAttribute)

Places an attribute at att_id, growing the attribute list if needed.

Mirrors C++ PointCloud::SetAttribute: the attribute’s unique id is set to att_id. Any vacancies created when growing the list are filled with empty attributes.

pub fn num_attributes(&self) -> i32

Returns the number of attributes.

pub fn attribute_id_by_unique_id(&self, unique_id: u32) -> i32

Returns the attribute id for the given Draco unique id, or -1.

Mirrors C++ PointCloud::GetAttributeIdByUniqueId.

pub fn attribute_by_unique_id(&self, unique_id: u32) -> Option<&PointAttribute>

Returns the attribute with the given Draco unique id.

Mirrors C++ PointCloud::GetAttributeByUniqueId.

pub fn attribute(&self, att_id: i32) -> &PointAttribute

Returns an attribute by attribute id.

pub fn try_attribute(&self, att_id: i32) -> Result<&PointAttribute, DracoError>

Fallibly returns an attribute by attribute id.

pub fn attribute_mut(&mut self, att_id: i32) -> &mut PointAttribute

Returns a mutable attribute by attribute id.

pub fn try_attribute_mut( &mut self, att_id: i32, ) -> Result<&mut PointAttribute, DracoError>

Fallibly returns a mutable attribute by attribute id.

pub fn named_attribute_id(&self, att_type: GeometryAttributeType) -> i32

Returns the first attribute id with the requested semantic type, or -1.

pub fn named_attribute( &self, att_type: GeometryAttributeType, ) -> Option<&PointAttribute>

Returns the first attribute with the requested semantic type.

pub fn num_points(&self) -> usize

Returns the number of logical points.

pub fn metadata(&self) -> Option<&GeometryMetadata>

Returns geometry metadata, if present.

pub fn metadata_mut(&mut self) -> Option<&mut GeometryMetadata>

Returns mutable geometry metadata, if present.

pub fn metadata_or_insert(&mut self) -> &mut GeometryMetadata

Returns geometry metadata, inserting an empty block when absent.

pub fn set_metadata(&mut self, metadata: Option<GeometryMetadata>)

Replaces geometry metadata.

pub fn attribute_metadata_by_unique_id( &self, attribute_unique_id: u32, ) -> Option<&AttributeMetadata>

Finds per-attribute metadata by Draco attribute unique id.

pub fn attribute_metadata_by_string_entry( &self, entry_name: &str, entry_value: &str, ) -> Option<&AttributeMetadata>

Finds per-attribute metadata by a string metadata entry.

pub fn set_attribute_metadata( &mut self, att_id: i32, metadata: Metadata, ) -> Result<(), DracoError>

Sets metadata for an attribute id.

Trait Implementations

Performs copy-assignment from source.

impl Debug for PointCloud

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