Method GetFaceMesh

GetFaceMesh(TrackableId, Allocator, ref XRFaceMesh)

Get the mesh data associated with the face with faceId. The faceMesh should be reused if it is the correct size; otherwise, its arrays should be reallocated with allocator. Use Resize(int, int, Attributes, Allocator) to resize the containers for face mesh data.

Declaration

public virtual void GetFaceMesh(TrackableId faceId, Allocator allocator, ref XRFaceMesh faceMesh)

Parameters

Type	Name	Description
TrackableId	faceId	The TrackableId for a XRFace.
Allocator	allocator	The allocator to use for the returned data if a resize is necessary.
XRFaceMesh	faceMesh	The container for the mesh data to either re-use or re-allocate.

Examples

var vertices = faceMesh.vertices;
CreateOrResizeNativeArrayIfNecessary(numVertices, allocator, ref vertices);

...

faceMesh.Assign(new XRFaceMesh
{
    vertices = vertices,
    indices = ...
});
