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.
