virtual boolean MCCOMAPI | NeedKeyFrameTangents () const |
Basic Tweener class. Derive from this for a default implementation of I3DExTweener
virtual uint32 MCCOMAPI TBasicTweener::AddRef | ( | ) | [inline, virtual] |
Increments the reference count of the object
Reimplemented from TBasicDataExchanger.
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.
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 |
Implements I3DExTweener.
virtual boolean MCCOMAPI TBasicTweener::NeedKeyFrameTangents | ( | ) | const [inline, virtual] |
Returns true if the tweener need to have tangents on the keyframes.
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.
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.
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
