Detailed Description

Abstract class defining the interface of a Timer to be implemented by rendering systems.

Remarks:

The Ogre::Timer needs to be bound to a specific single core on multi processor machines to calculate correct high performance timings. Using this timer would cause both the graphic and haptic rendering to be virtually performed on a single core, leaving other cores almost idle.

Some haptic API's provide their own timers. This class provides a unified interface to wrap these timers. This is useful in the abstract Device class, allowing to request the timer of its creator (e.g. RenderSystem) and as such using consistent timings in its calculations.

For client application it is advised not to use these timers, unless it is used in calculations needed for haptic rendering.
