Detailed Description

An Animation Method defines the trajectory of an object. For instance, an object can be animation by interpolating between positions (key frames) or using a physical simulation...

There are two interfaces to access a component: The shell interface (ISh. or I3DSh.) and the external interface (IEx. or I3DEx.) . You can get one from the other using QueryInterface.

Whenever it is possible you should use the Shell interface to access the component because the Shell will make sure that the parameter map of the external component is valid. This is especially important if the component is animated. For more information on components see the Overview of the SDK.

Member Function Documentation

virtual MCCOMErr MCCOMAPI I3DExAnimationMethod::BeginConvert ( I3DShAnimationMethod source  )  [pure virtual]

Starts the conversion from one animation method to another.

Note that this method is only called if the GetXTranslationAnimationTrack are not implemented.

Parameters:
source The source animation method.

Implemented in TBasicAnimationMethod.

virtual MCCOMErr MCCOMAPI I3DExAnimationMethod::Convert ( I3DShAnimationMethod source,
const TTreeTransform transform 
) [pure virtual]

Converts one position (transform) at the current time from one animation method to another. This method is called for each of the times returned by GetAnimationKeyTimes().

Parameters:
source The source animation method.
transform The transform at the current time from the source animation method.

Implemented in TBasicAnimationMethod.

virtual MCCOMErr MCCOMAPI I3DExAnimationMethod::EndConvert ( I3DShAnimationMethod source  )  [pure virtual]

Called at the end of the conversion from one animation method to another. See BeginConvert() and Convert() for details.

Implemented in TBasicAnimationMethod.

virtual MCCOMErr MCCOMAPI I3DExAnimationMethod::GetAnimationKeyTimes ( real  inAccuracy,
TMCArray< MicroTick > &  outKeyTimes,
boolean outAutoGetKeyFrames,
boolean outAutoCurveAnalysis 
) [pure virtual]

Returns a set of key times that approximates the trajectory of the object with a given accuracy. This is used when converting an animation method to key frames.

Note that by setting outAutoCurveAnalysis or outAutoGetKeyFrames to true, you can tell the Shell to use a default implementation to evaluate the keyframes so that you do not have to provide an implementation of this method

Parameters:
inAccuracy The accuray of the conversion (0 is the lowest accuracy, 1 means 100%)
outKeyTimes The returned sampling times.
outAutoGetKeyFrames Returns true if the keyframes of the animation method should be used instead.
outAutoCurveAnalysis Retursn true if a default curve analysis method should be used instead.

Implemented in TBasicAnimationMethod.

virtual MCCOMErr MCCOMAPI I3DExAnimationMethod::GetHotPointAnimationTrack ( I3DShParamTimeLine **  animationTrack  )  [pure virtual]

Implemented in TBasicAnimationMethod.

virtual boolean MCCOMAPI I3DExAnimationMethod::GetInitialTransform ( TTreeTransform transform  )  [pure virtual]

Implemented in TBasicAnimationMethod.

Returns:
true if the transform is local
