Member Function Documentation

virtual uint32 MCCOMAPI TBasicTweener::AddRef (   )  [inline, virtual]

Increments the reference count of the object Reimplemented from TBasicUnknown.

virtual MCCOMErr MCCOMAPI TBasicTweener::Derivate (  I3DShKeyFrame *  res, int32  time, I3DShTweenerChainLink *  alink )  [virtual]

Calculate the first derivative of the value as a function of time. This function is used for motion blur and should be implemented so that your tweener is compatible with the motion blur. Parameters: res  : keyFrame where the result is stored time  : time at which the tweener should be evaluated alink  : link between the two keyframes where time is located Returns: MC_S_OK if it executed properly. MC_E_NOTIMPL if it is not implemented Implements I3DExTweener.

virtual MCCOMErr MCCOMAPI TBasicTweener::QueryInterface (  const MCIID &  riid, void **  ppvObj )  [virtual]

Check if the object supports a given interface and returns a pointer to that interface if it does. Note that QueryInterface will increment the reference count of the object by one if the interface is found. Parameters: riid  GUID of the interface ppvObj  A pointer to the pointer being returned. Reimplemented from TBasicDataExchanger.

virtual MCCOMErr MCCOMAPI TBasicTweener::SimpleTween (  real &  result, int32  time, int32  time1, int32  time2 )  [virtual]

Implements I3DExTweener.

virtual MCCOMErr MCCOMAPI TBasicTweener::Tween (  I3DShKeyFrame *  res, int32  time, I3DShTweenerChainLink *  alink )  [virtual]

Interpolates a value between two keyframes. Parameters: res  : keyFrame where the result is stored time  : time at which the tweener should be evaluated alink  : link between the two keyframes where time is located -Returns: MC_S_OK if it executed properly. MC_E_NOTIMPL if it is not implemented Implements I3DExTweener.
