Inheritance diagram for KFbxPose:

Detailed Description

This class contains the description of a Pose manager.

TheKFbxPoseobject can be setup to hold "Bind Pose" data or "Rest Pose" data.

The Bind Pose holds the transformation (translation, rotation and scaling) matrix of all the nodes implied in a link deformation. This includes the geometry being deformed, the links deforming the geometry, and recursively all the ancestors nodes of the link. The Bind Pose gives you the transformation of the nodes at the moment of the binding operation when no deformation occurs.

The Rest Pose is a snapshot of a node transformation. A Rest Pose can be used to store the position of every node of a character at a certain point in time. This pose can then be used as a reference position for animation tasks, like editing walk cycles.

One difference between the two modes is in the validation performed before adding an item and the kind of matrix stored.

In "Bind Pose" mode, the matrix is assumed to be defined in the global space, while in "Rest Pose" the type of the matrix may be specified by the caller. So local system matrices can be used. Actually, because there is one such flag for each entry (KFbxPoseInfo), it is possible to have mixed types in aKFbxPoseelements. It is therefore the responsability of the caller to check for the type of the retrieved matrix and to do the appropriate conversions if required.

The validation of the data to be added consists of the following steps:

If thisKFbxPoseobject stores "Bind Poses", then add aKFbxPoseInfoonly if the node is not already associated to another "Bind Pose". This check is done by visiting ALL theKFbxPoseobjects in the system.

The above test is only performed for the "Bind Pose" type. While the next one is always performed, no matter what kind of poses thisKFbxPoseobject is setup to hold.

If a node is already inserted in theKFbxPoseinternal list, then the passed matrix MUST be equal to the one already stored. If this is not the case, the Add method will return -1, indicating that no newKFbxPoseInfohas been created.

If the Add method succeeds, it will return the index of theKFbxPoseInfostructure that as been created and held by theKFbxPoseobject.

To ensure data integrity, the stored information can only be accessed using the provided methods (read-only). If an entry needs to be modified, the caller has to remove theKFbxPoseInfoitem by calling Remove(i) and then Add a new one.

The internal list is not ordered and the search inside this is list is linear (from the first element to ... the first match or the end of the list).

bool IsValidBindPose	(	KFbxNode*	pRoot,
		double	pMatrixCmpTolerance=`0.0001`
	)

Check this bindpose and report an error if all the conditions to a valid bind pose are not met.

The conditions are:

a) We are a BindPose. b) For every node in the bind pose, all their parent node are part of the bind pose. c) All the deforming nodes are part of the bind pose. d) All the parents of the deforming nodes are part of the bind pose. e) Each deformer relative matrix correspond to the deformer Inv(bindMatrix) * deformed Geometry bindMatrix.

Parameters:

	pRoot	This node is used as the stop point when visiting the parents (cannot be NULL).
	pMatrixCmpTolerance	Tolerance value when comparing the matrices.

Returns:: true if all the above conditions are met and false otherwise.

Remarks:: If the returned value is false, querying for the error will return the reason of the failure. As soon as one of the above conditions is not met, this method return ignoring any subsequent errors. Run the IsBindPoseVerbose if more details are needed.

bool IsValidBindPoseVerbose	(	KFbxNode*	pRoot,

		KArrayTemplate<KFbxNode*>&	pWrongMatrices,
		double	pMatrixCmpTolerance=`0.0001`
	)

Same as IsValidBindPose but slower because it will not stop as soon as a failure occurs.

Instead, keeps running to accumulate the faulty nodes (stored in the appropriate array). It is then up to the caller to fill the UserNotification if desired.

Parameters:

	pRoot	This node is used as the stop point when visiting the parents (cannot be NULL).
	pMissingAncestors	Each ancestor missing from the BindPose is added to this list.
	pMissingDeformers	Each deformer missing from the BindPose is added to this list.
	pMissingDeformersAncestors	Each deformer ancestors missing from the BindPose is added to this list.
	pWrongMatrices	Nodes that yeld to a wrong matric comparisons are added to this list.
	pMatrixCmpTolerance	Tolerance value when comparing the matrices.

bool IsValidBindPoseVerbose	(	KFbxNode*	pRoot,
		KFbxUserNotification*	pUserNotification,
		double	pMatrixCmpTolerance=`0.0001`
	)

Same as IsValidBindPose but slower because it will not stop as soon as a failure occurs.

Instead, keeps running to accumulate the faulty nodes and send them directly to the UserNotification.

Parameters:

	pRoot	This node is used as the stop point when visiting the parents (cannot be NULL).
	pUserNotification	Pointer to the user notification where the messages will be accumulated.
	pMatrixCmpTolerance	Tolerance value when comparing the matrices.

Remarks:: If the pUserNotification parameter is NULL, this method will call IsValidBindPose.

KError&GetError ( )

Retrieve error object.

Returns:: Reference to error object.

EErrorGetLastErrorID ( ) const

Get last error code.

Returns:: Last error code.

const char* GetLastErrorString ( ) const

Get last error string.

Returns:: Textual description of the last error.
