Detailed Description

This class describes a functor for orientations using discrete samples.

The resulting functor will interpolate the orientations using spheric linear quaternion interpolation. The mInitialTimestamp and mFinalTimestamp members will be mapped with the animation's duration (meaning that initial timestamp correspond to animation start, and final timestamp will be mapped to animation end) The descriptor must contain at leats one orientation value.

Constructor & Destructor Documentation

VgEngine::VgDiscreteQuaternionFunctorDescriptor::VgDiscreteQuaternionFunctorDescriptor ( ) [protected]

Class constructor.

This can't be called publicly, instances must be obtained through the VgDiscreteQuaternionFunctorDescriptor::create method.

virtual VgEngine::VgDiscreteQuaternionFunctorDescriptor::~VgDiscreteQuaternionFunctorDescriptor ( ) [protected, virtual]

Class destructor.

Member Function Documentation

static VgEngine::VgRefPtr< VgEngine::VgDiscreteQuaternionFunctorDescriptor > VgEngine::VgDiscreteQuaternionFunctorDescriptor::create ( ) [static]

This static method returns a new heap-allocated descriptor.

It is the only method that should be used to instantiate new descriptors. It is a way to make sure no one will delete it, except the last VgRefPtr pointing to it.
