Methods

Method	Description
IXRGeneralTransform::Transform	Transforms the specified x-y coordinate, and returns the target x-y coordinate.
IXRGeneralTransform::TransformBounds	Transforms the specified bounding box and returns an axis-aligned bounding box that is exactly large enough to contain it.

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

A transform defines how to map points from one coordinate space into another coordinate space. Transforms can be used to produce effects such as rotation, scaling, and skewing. Typically, an application developer uses one of the derived classes to transform an object.

If you create a class instance, use an IXRGeneralTransformPtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.
