Struct XRFaceMesh

Container for mesh data associated with an XRFace. Not all implementations support all data. Check for existence with NativeArray's IsCreated property.

Inherited Members

Object.Equals(Object, Object)

Object.ReferenceEquals(Object, Object)

Object.GetType()

Namespace: UnityEngine.XR.ARSubsystems

Syntax

public struct XRFaceMesh : IEquatable<XRFaceMesh>, IDisposable

Properties

indices

The triangle indices of the mesh. There are three times as many indices as triangles.

Declaration

public readonly NativeArray<int> indices { get; }

Property Value

Type	Description
Unity.Collections.NativeArray<Int32>

normals

The normals in the mesh. This is a parallel array to vertices and uvs.

Declaration

public readonly NativeArray<Vector3> normals { get; }

Property Value

Type	Description
Unity.Collections.NativeArray<UnityEngine.Vector3>

uvs

The texture coordinates for the mesh. This is a parallel array to vertices and normals.

Declaration

public readonly NativeArray<Vector2> uvs { get; }

Property Value

Type	Description
Unity.Collections.NativeArray<UnityEngine.Vector2>

vertices

The vertices in the mesh. This is a parallel array to normals and uvs.

Declaration

public readonly NativeArray<Vector3> vertices { get; }

Property Value

Type	Description
Unity.Collections.NativeArray<UnityEngine.Vector3>

Methods

Dispose()

Disposes of the all four native arrays: vertices, normals, uvs, and indices. Checking for creation before calling Dispose.

Declaration

public void Dispose()

Implements

IDisposable.Dispose()

Equals(Object)

Tests for equality.

Declaration

public override bool Equals(object obj)

Parameters

Type	Name	Description
Object	obj	The object to compare against.

Returns

Type	Description
Boolean	True if obj is of type XRFaceMesh and Equals(XRFaceMesh) also returns true; otherwise false.

Overrides

ValueType.Equals(Object)

Equals(XRFaceMesh)

Tests for equality.

Declaration

public bool Equals(XRFaceMesh other)

Parameters

Type	Name	Description
XRFaceMesh	other	The other XRFaceMesh to compare against.

Returns

Type	Description
Boolean	True if every field in other is equal to this XRFaceMesh, otherwise false.

Implements

IEquatable<T>.Equals(T)

GetHashCode()

Generates a hash suitable for use with containers like HashSet and Dictionary.

Declaration

public override int GetHashCode()

Returns

Type	Description
Int32	A hash code generated from this object's fields.

Overrides

ValueType.GetHashCode()

Resize(Int32, Int32, XRFaceMesh.Attributes, Allocator)

Resize the NativeArrays held by this struct. This method will deallocate the NativeArrays if they are not needed or if they are not the correct size. If they are already the correct size, this method does not mutate those NativeArrays. This facilitate memory reuse when the number of vertices or triangles in the face does not change frequently.

Declaration

public void Resize(int vertexCount, int triangleCount, XRFaceMesh.Attributes attributes, Allocator allocator)

Parameters

Type	Name	Description
Int32	vertexCount	The number of vertices in the mesh.
Int32	triangleCount	The number of triangles in the mesh.
XRFaceMesh.Attributes	attributes	Optional mesh attributes. This affects whether normals and uvs will be (re)allocated or disposed.
Unity.Collections.Allocator	allocator	If a reallocation is required, this allocator will be used.

ToString()

Generates a string suitable for debugging purposes.

Declaration

public override string ToString()

Returns

Type	Description
String	A string representation of this XRFaceMesh.

Overrides

ValueType.ToString()

Operators

Equality(XRFaceMesh, XRFaceMesh)

Tests for equality. Same as Equals(XRFaceMesh).

Declaration

public static bool operator ==(XRFaceMesh lhs, XRFaceMesh rhs)

Parameters

Type	Name	Description
XRFaceMesh	lhs	The left-hand side of the comparison.
XRFaceMesh	rhs	The right-hand side of the comparison.

Returns

Type	Description
Boolean	True if lhs is equal to rhs, otherwise false.

Inequality(XRFaceMesh, XRFaceMesh)

Tests for inequality. Same as !Equals(XRFaceMesh).

Declaration

public static bool operator !=(XRFaceMesh lhs, XRFaceMesh rhs)

Parameters

Type	Name	Description
XRFaceMesh	lhs	The left-hand side of the comparison.
XRFaceMesh	rhs	The right-hand side of the comparison.

Returns

Type	Description
Boolean	True if lhs is not equal to rhs, otherwise false.
