    Struct XRFaceMesh

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

    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 NativeArray<int> indices { get; }
    Property Value
    Type Description
    NativeArray<Int32>

    normals

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

    Declaration
    public NativeArray<Vector3> normals { get; }
    Property Value
    Type Description
    NativeArray<Vector3>

    uvs

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

    Declaration
    public NativeArray<Vector2> uvs { get; }
    Property Value
    Type Description
    NativeArray<Vector2>

    vertices

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

    Declaration
    public NativeArray<Vector3> vertices { get; }
    Property Value
    Type Description
    NativeArray<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()

    Equals(Object)

    Declaration
    public override bool Equals(object obj)
    Parameters
    Type Name Description
    Object obj
    Returns
    Type Description
    Boolean
    Overrides
    ValueType.Equals(Object)

    Equals(XRFaceMesh)

    Declaration
    public bool Equals(XRFaceMesh other)
    Parameters
    Type Name Description
    XRFaceMesh other
    Returns
    Type Description
    Boolean

    GetHashCode()

    Declaration
    public override int GetHashCode()
    Returns
    Type Description
    Int32
    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.

    Allocator allocator

    If a reallocation is required, this allocator will be used.

    ToString()

    Declaration
    public override string ToString()
    Returns
    Type Description
    String
    Overrides
    ValueType.ToString()

    Operators

    Equality(XRFaceMesh, XRFaceMesh)

    Declaration
    public static bool operator ==(XRFaceMesh lhs, XRFaceMesh rhs)
    Parameters
    Type Name Description
    XRFaceMesh lhs
    XRFaceMesh rhs
    Returns
    Type Description
    Boolean

    Inequality(XRFaceMesh, XRFaceMesh)

    Declaration
    public static bool operator !=(XRFaceMesh lhs, XRFaceMesh rhs)
    Parameters
    Type Name Description
    XRFaceMesh lhs
    XRFaceMesh rhs
    Returns
    Type Description
    Boolean
