TextBlockVisual3DIsTwoSidedText Property

Gets or sets a Boolean that specifies if the plane 3D models shows text on both front and back sides. If IsTwoSidedText is false, then only the front material is set. This can improve performance because the text is rendered only once. Default value is true. To control orientation of the back sided text, see also the IsBackSidedTextFlipped property.

public bool IsTwoSidedText { get; set; }
