public class VgAxialRotationQuaternionFunctorDescriptor
extends VgFunctorDescriptor

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.

Method Detail

delete

public void delete()

Overrides:

delete in class VgFunctorDescriptor

create

public static VgAxialRotationQuaternionFunctorDescriptorRefPtr create()

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.

setMPreOrientation

public void setMPreOrientation(VgOrientation value)

The pre-orientation value. This will be applied each time the functor is evaluated, before the interpolated orientation.

getMPreOrientation

public VgOrientation getMPreOrientation()

The pre-orientation value. This will be applied each time the functor is evaluated, before the interpolated orientation.

setMAxis

public void setMAxis(float[] value)

The rotation axis.

Warning:

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

getMAxis

public float[] getMAxis()

The rotation axis.

Warning:

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

setMStartAngle

public void setMStartAngle(float value)

This is the starting rotation angle (in degrees).

getMStartAngle

public float getMStartAngle()

This is the starting rotation angle (in degrees).

setMEndAngle

public void setMEndAngle(float value)

This is the target rotation angle (in degrees).

getMEndAngle

public float getMEndAngle()

This is the target rotation angle (in degrees).

setMCubic

public void setMCubic(boolean value)

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

getMCubic

public boolean getMCubic()

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