HandMeshVertexState.UpdateTimestamp Property

Definition

Gets the timestamp at which the vertex positions and normals were last updated.

public:
 property PerceptionTimestamp ^ UpdateTimestamp { PerceptionTimestamp ^ get(); };
PerceptionTimestamp UpdateTimestamp();
public PerceptionTimestamp UpdateTimestamp { get; }
var perceptionTimestamp = handMeshVertexState.updateTimestamp;
Public ReadOnly Property UpdateTimestamp As PerceptionTimestamp

Property Value

The update timestamp.

Remarks

The vertex positions and normals will generally be updated each frame. However, if the UpdateTimestamp remains the same across two frames, you can skip ingesting the vertex buffer, as it also remains the same. Note that you should still get the latest CoordinateSystem value every frame even if the vertex buffer hasn't changed, to best reposition the old mesh for the hand's new location this frame.
