Detailed Description
-
class HBhvInterpolatorAxisRotate : public HBhvInterpolator
The HBhvInterpolatorAxisRotate class controls rotation around an arbitrary axis.
Public Functions
-
HBhvInterpolatorAxisRotate(HBhvAnimation *animation = 0, char const *name = 0)
Constructs an HBhvInterpolatorAxisRotate object.
- Parameters
animation – The animation that this interpolator belongs to.
name – The name of of the interpolator.
-
inline void SetAxis(float x, float y, float z)
Sets the axis of rotation.
-
virtual char const *GetType()
- Returns
The type of the interpolator which is ‘AxisRot’.
-
virtual HBhvInterpolator *CreateInstance(HBhvAnimation *ainst)
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.
- Parameters
ainst – The animation instance that this interpolator is associated with.
- Returns
The newly created interpolator that references this interpolator.
-
inline void Insert(float angle, int l = 0)
This method creates a new axis rotation keyframe with the passed angle value and then inserts it after the passed position l into the keyframe array.
- Parameters
angle – The angle for the new keyframe.
l – The array position to insert new keyframe after.
-
inline void Replace(float angle, int l)
Replaces the item at the given position in the keyframe array with a new axis rotation keyframe that was created with the passed angle value.
- Parameters
angle – The angle for the replacement keyframe.
l – The array position to replace.
-
virtual void Serialize(HUtilityXMLGenerator *xmlgen)
Writes XML data to a buffer using the passed XML generator.
-
virtual void Interpolate(int keyframe, float fraction)
Performs interpolation on the animation target.
- Parameters
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.
Public Static Functions
-
static void *XMLCallback(HUtilityXMLTag *xt, bool open, void *m_pExtraData)
This is XML read callback which parses XML data and then populates the member variables with the associated values.
