Struct Attribute 

pub struct Attribute { /* private fields */ }

Represents an attribute in a mesh. An attribute can be an array of values representing potisions of vertices, or it can be an array of values representing normals of vertices or corners, or faces. Note that the struct does not have the static type information, so the attribute value can be a vector of any type of any dimension, as long as it implements the Vector trait. The information about the type of the attribute, component type, and the number of components is stored in dynamically.

Implementations

impl Attribute

pub fn new<Data, const N: usize>( data: Vec<Data>, att_type: AttributeType, domain: AttributeDomain, parents: Vec<AttributeId>, ) -> Self

where Data: Vector<N>,

pub fn new_empty( id: AttributeId, att_type: AttributeType, domain: AttributeDomain, component_type: ComponentDataType, num_components: usize, ) -> Self

pub fn get<Data, const N: usize>(&self, p_idx: PointIdx) -> Data

where Data: Vector<N>, Data::Component: DataValue,

pub fn get_unique_val<Data, const N: usize>( &self, val_idx: AttributeValueIdx, ) -> Data

where Data: Vector<N>, Data::Component: DataValue,

pub fn get_component_type(&self) -> ComponentDataType

pub fn get_id(&self) -> AttributeId

pub fn get_num_components(&self) -> usize

pub fn get_attribute_type(&self) -> AttributeType

pub fn get_domain(&self) -> AttributeDomain

pub fn get_parents(&self) -> &Vec<AttributeId>

pub fn len(&self) -> usize

The number of values of the attribute.

pub fn num_unique_values(&self) -> usize

pub fn get_unique_val_idx(&self, idx: PointIdx) -> AttributeValueIdx

pub fn set_name(&mut self, name: String)

pub fn get_name(&self) -> Option<&String>

pub fn unique_vals_as_slice<Data>(&self) -> &[Data]

returns the data values as a slice of values casted to the given type.

pub fn unique_vals_as_slice_mut<Data>(&mut self) -> &mut [Data]

returns the data values as a mutable slice of values casted to the given type.

pub unsafe fn unique_vals_as_slice_unchecked<Data>(&self) -> &[Data]

returns the data values as a slice of values casted to the given type.

Safety:

This function assumes that the buffer’s data is properly aligned and matches the type Data.

pub unsafe fn unique_vals_as_slice_unchecked_mut<Data>(&mut self) -> &mut [Data]

returns the data values as a mutable slice of values casted to the given type.

Safety:

This function assumes that the buffer’s data is properly aligned and matches the type Data.

pub fn permute(&mut self, indices: &[usize])

permutes the data in the buffer according to the given indices, i.e. i-th element in the buffer will be moved to indices[i]-th position.

pub fn permute_unchecked(&mut self, indices: &[usize])

permutes the data in the buffer according to the given indices, i.e. i-th element in the buffer will be moved to indices[i]-th position.

Safety:

This function assumes that the indices are valid, i.e. they are within the bounds of the buffer.

pub fn swap(&mut self, i: usize, j: usize)

swaps the elements at indices i and j in the buffer.

pub fn take_values<Data, const N: usize>(self) -> Vec<Data>

where Data: Vector<N>,

pub fn into_parts<Data, const N: usize>( self, ) -> (Vec<Data>, Option<VecPointIdx<AttributeValueIdx>>, Self)

where Data: Vector<N>,

pub fn set_values<Data, const N: usize>(&mut self, data: Vec<Data>)

where Data: Vector<N>,

pub fn remove_duplicate_values<Data, const N: usize>(&mut self)

where Data: Vector<N>,

pub fn remove_unique_val_dyn(&mut self, val_idx: usize)
