Remarks2D shapes can be rendered using an outline and filled interior. The stroke properties (see StrokeColor, StrokeAlpha, StrokeThickness and StrokeDashPattern) define the line style used for the outline. If StrokeAlpha or the StrokeThickness is 0, no outlines are rendered. The fill properties (see FillColor and FillAlpha) define the fill color. If FillAlpha is 0, the interior of the figure is not filled. Some shapes, like simple line segments, do not have an interior which can be filled and the fill properties are ignored.
3D lines, even closed 3D curves, do not have an interior and are also not filled.
If pose, scale, figure and other properties are constant, it is recommended to set the IsStatic flag to . If this flag is set, the figure renderer can perform optimizations.
Cloning: When a FigureNode is cloned the Figure is not duplicated. The Figure is copied by reference (shallow copy). The original FigureNode and the cloned instance will reference the same Figure.
