TriangleMeshTVertices Property

Array of vertices of the specified type T. When the data in the Vertices array are changed and if this mesh was already initialized (IsInitialized is true) then you need to call UpdateMesh or UpdateMesh(BoundingBox) method for the changes to take effect. When the Vertices property is changed to another array, then UpdateMesh is called automatically. Changing Vertices also calculates the new BoundingBox.

public T[]? Vertices { get; set; }
