HBhvInterpolatorScale::HBhvInterpolatorScale | ( | HBhvAnimation * | animation = 0 , |
|
const char * | name = 0 | |||
) |
Constructs an HBhvInterpolatorScale object.
animation | The animation that this interpolator belongs to. | |
name | The name of the interpolator. |
virtual void HBhvInterpolatorScale::CalculateAllTangents | ( | ) | [virtual] |
This is a helper method that calculates the tangents for all the entries in the keyframe array. You can call this method before doing an interpolation.
virtual void HBhvInterpolatorScale::CalculatePos | ( | int | keyframe, | |
float | fraction, | |||
HPoint & | res | |||
) | [virtual] |
Calculates the interpolated positional value given a keyframe and fraction to the next keyframe.
keyframe | The reference keyframe for this interpolation/ | |
fraction | The fractional value from the specified keyframe to the next keyframe. This value is from 0 to 1. | |
res | The result of the interpolation. |
virtual HBhvInterpolator* HBhvInterpolatorScale::CreateInstance | ( | HBhvAnimation * | ainst | ) | [virtual] |
In special cases, you may want an interpolator that references this interpolator without changing it. Use this method to create the new interpolator passing a pointer to the animation that you want it to be associated with.
ainst | The animation instance that this interpolator is associated with. |
Implements HBhvInterpolator.
const char* HBhvInterpolatorScale::GetType | ( | ) | [virtual] |
void HBhvInterpolatorScale::Insert | ( | HPoint | pos, | |
int | l = 0 | |||
) | [inline] |
This method creates a new keyframe with the passed scaling factor and then inserts it after the given position l in the keyframe array.
pos | The scale factors for the new keyframe. | |
l | The array position to insert item after. |

virtual void HBhvInterpolatorScale::Interpolate | ( | int | keyframe, | |
float | fraction | |||
) | [virtual] |
Performs an interpolation on the animation target.
keyframe | The reference keyframe for this interpolation. | |
fraction | The fraction value from the specified keyframe to the next keyframe. The value is from 0 to 1. |
Reimplemented from HBhvInterpolator.
virtual void HBhvInterpolatorScale::InterpolateCamera | ( | HPoint & | Scale, | |
bool | simulate = false | |||
) | [protected, virtual] |
Calculates the interpolated camera orientation and position for camera types that are position driven.
pos | New Camera Position Reference |
virtual void HBhvInterpolatorScale::InterpolateCamera2 | ( | HPoint & | Scale, | |
bool | simulate = false | |||
) | [protected, virtual] |
Calculates the interpolated camera orientation for camera types that are target driven.
pos | New Camera Position Reference |
void HBhvInterpolatorScale::Replace | ( | HPoint | pos, | |
int | l | |||
) | [inline] |
Replaces the item at the given position in the keyframe array with a new keyframe that was created with the passed scaling factors.
pos | The scale factors for the replacement keyframe. | |
l | The array position to replace. |

virtual void HBhvInterpolatorScale::Reset | ( | ) | [virtual] |
Resets this interpolator instance.
Reimplemented from HBhvInterpolator.
virtual void HBhvInterpolatorScale::Serialize | ( | HUtilityXMLGenerator * | xmlgen | ) | [virtual] |
Writes XML data to a buffer using the passed XML generator.
Reimplemented from HBhvInterpolator.
static void* HBhvInterpolatorScale::XMLCallback | ( | HUtilityXMLTag * | xt, | |
bool | open, | |||
void * | m_pExtraData | |||
) | [static] |
This is XML read callback which parses XML data and then populates the member variables with the associated values.
