Thread Safety
Members of this class are thread-safe if you previously called IXRApplication::CreateHostFromXaml and supplied it with an XRWindowCreateParams structure that has AllowsMultipleThreadAccess set to true.
Remarks
Use an IXRPathFigure object to store IXRBezierSegment objects and other segments.
Four points define a cubic Bézier curve: a starting point, an endpoint (Point3), and two control points (Point1 and Point2). The IXRBezierSegment class does not contain a property for the starting point of the curve. The starting point of the curve is the current point of the IXRPathFigure that contains the IXRBezierSegment.
The two control points of a cubic Bézier curve attract parts of a line between the starting point and the endpoint and produce a curve. The curve does not necessarily pass through either of the control points.
To specify a Bézier segment with more control points, see IXRPolyBezierSegment.
When you create a class instance, use an IXRBezierSegmentPtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.
You can also define an IXRBezierSegment object in Microsoft Silverlight 3 XAML. For information about the differences between XAML in XAML for Windows Embedded and Silverlight 3, see Differences Between Microsoft Silverlight 3 and XAML for Windows Embedded. For more information about how to define this element in the source XAML for your application, see the BezierSegment Class on MSDN.
