Detailed Description

This class implements descriptors for axial rotation functors.

It will simply interpolate between two angle values and apply rotation of the given angle along the axis. It is possible to set the functor to use a cubic function to have acceleration at start and deceleration at end. There is a possibility of setting a fixed pre-orientation value that will be applied prior to the interpolation's value.

Class constructor.

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

)

[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.

Member Data Documentation

float VgEngine::VgAxialRotationQuaternionFunctorDescriptor::mAxis[3]

The rotation axis.

Warning:

If axis vector length is not long enough (below 1e-6), the functor creation will fail.

Version:

2.0.7729

bool VgEngine::VgAxialRotationQuaternionFunctorDescriptor::mCubic

This boolean value tells whether a cubic function should be used to add acceleration and deceleration (true) or pure linear with constant velocity (false).

Version:

2.0.7729

float VgEngine::VgAxialRotationQuaternionFunctorDescriptor::mEndAngle

This is the target rotation angle (in degrees).

Version:

2.0.7729

VgOrientation VgEngine::VgAxialRotationQuaternionFunctorDescriptor::mPreOrientation

The pre-orientation value.

This will be applied each time the functor is evaluated, before the interpolated orientation.

Version:

2.0.7729

float VgEngine::VgAxialRotationQuaternionFunctorDescriptor::mStartAngle

This is the starting rotation angle (in degrees).
