Member Function Documentation

◆ GetName()

String GetName ( )

Retrieves the name of the morph.

Returns: The name of the morph.

◆ SetName()

void SetName ( const String & name )

Sets the name of the morph.

Parameters

[in] name The new name of the morph.

◆ GetID()

Int32 GetID ( )

Retrieves the internal ID of the morph. Each morph has an ID. This ensures that removed morphs do not affect the DescID for the sliders.

Returns: The internal ID of the morph.

◆ CopyFrom()

Bool CopyFrom	(	CAMorph *	src,
		AliasTrans *	trn,
		CAMORPH_COPY_FLAGS	flags
	)

Copies morph data from src.

Parameters

[in]	src	The source morph.
[in]	trn	An alias translator for the operation. Can be nullptr. The caller owns the pointed alias translator.
[in]	flags	The flags: CAMORPH_COPY_FLAGS

Returns: true if successful, otherwise false.

◆ Find()

CAMorphNode* Find	(	CAPoseMorphTag *	tag,
		BaseList2D *	bl
	)

Retrieves the morph node for the object specified by bl.

Note: A single morph can be applied to a hierarchy of objects, each has a representation in the morph as a CAMorphNode.

Parameters

[in]	tag	The morph tag containing the morph node.
[in]	bl	The object connected to the morph node.

Returns: The morph node for the specified object. The tag owns the pointed morph node.

◆ GetNodeIndex()

Int32 GetNodeIndex ( CAMorphNode * node )

Retrieves the index of the specified morph node. Each morph node can be accessed through their indices.

Parameters

[in] node The morph node to request the index.

Returns: The morph node index.

◆ FindIndex()

Int32 FindIndex	(	CAPoseMorphTag *	tag,
		BaseList2D *	bl
	)

Retrieves the index of the morph node for the object specified by bl.

Note: A single morph can be applied to a hierarchy of objects, each has a representation in the morph as a CAMorphNode.

Parameters

[in]	tag	The morph tag containing the morph node.
[in]	bl	The object connected to the morph node.

Returns: The index of the morph node of the specified object.

◆ FindFromIndex()

CAMorphNode* FindFromIndex	(	CAPoseMorphTag *	tag,
		Int32	index
	)

Retrieves the morph node specified by index.

Note: A single morph can be applied to a hierarchy of objects, each has a representation in the morph as a CAMorphNode.

Parameters

[in]	tag	The morph tag containing the morph node.
[in]	index	The index of the requested morph node.

Returns: The found morph node. The tag owns the pointed morph node.

◆ GetFirst()

CAMorphNode* GetFirst ( )

Retrieves the first node of the morph.

Returns: The first morph node. The tag owns the pointed morph node.

◆ SetMode()

Bool SetMode	(	BaseDocument *	doc,
		CAPoseMorphTag *	tag,
		CAMORPH_MODE_FLAGS	flags,
		CAMORPH_MODE	mode
	)

Changes the morph's mode.

Note: This is not the mode a user would change but data inside the morph. It must be restored to the original mode once changes are finished.
To change the morph tag's modes or parameters use C4DAtom::SetParameter().

Example: Point data could be stored as rotational or correctional and in a delta form (only differences from the base).
This can not be edited in this form so the data mode must be changed to relative (CAMORPH_MODE::REL) or absolute (CAMORPH_MODE::ABS) before editing and then restored to (CAMORPH_MODE::AUTO) when finished.
The flags must be passed as CAMORPH_MODE_FLAGS::EXPAND to expand the data from the delta form and then returned with CAMORPH_MODE_FLAGS::COLLAPSE when finished.
For example VAMP uses the following line to expand all data types to relative data:

smorph->SetMode(doc, data.s_morphtag, CAMORPH_MODE_FLAGS::ALL|CAMORPH_MODE_FLAGS::EXPAND,CAMORPH_MODE::REL);

CAMORPH_MODE_FLAGS::ALL

@ ALL

Expand or collapse all data.

CAMORPH_MODE_FLAGS::EXPAND

@ EXPAND

Expand data. Needs to be passed before accessing any data.

CAMORPH_MODE::REL

@ REL

Relative morph data.

doc

const char * doc

Definition: pyerrors.h:226

It then does some changes and finally restores all types to collapsed (delta) form and to the users mode (AUTO):

data.sources[i]->SetMode(doc, data.s_morphtag, CAMORPH_MODE_FLAGS::ALL|CAMORPH_MODE_FLAGS::COLLAPSE,CAMORPH_MODE::AUTO);

i

Py_ssize_t i

Definition: abstract.h:645

CAMORPH_MODE_FLAGS::COLLAPSE

@ COLLAPSE

Collapse data. Needs to be passed to collapse the expanded data, for instance after data access.

CAMORPH_MODE::AUTO

@ AUTO

Auto mode. Used to collapse the data automatically into their correct mode.

Parameters

[in]	doc	The document containing the morph tag.
[in]	tag	The morph tag containing the morph data.
[in]	flags	The flags: CAMORPH_MODE_FLAGS
[in]	mode	The mode: CAMORPH_MODE

Returns: true if successful, otherwise false.

◆ Store()

Bool Store	(	BaseDocument *	doc,
		CAPoseMorphTag *	tag,
		CAMORPH_DATA_FLAGS	flags
	)

Stores the current object's state into the morph.
The corresponding flags have to be set for the data. This should normally be CAMORPH_DATA_FLAGS::ASTAG if it is to be used by the user.

Parameters

[in]	doc	The document containing the morph tag.
[in]	tag	The morph tag containing the morph data.
[in]	flags	The flags: CAMORPH_DATA_FLAGS

Returns: true if successful, otherwise false.

◆ Apply()

Bool Apply	(	BaseDocument *	doc,
		CAPoseMorphTag *	tag,
		CAMORPH_DATA_FLAGS	flags
	)

Applies the morph to the object. The data to be applied is set with the flags.

Parameters

[in]	doc	The document containing the morph tag.
[in]	tag	The morph tag containing the morph data.
[in]	flags	The flags: CAMORPH_DATA_FLAGS

Returns: true if successful, otherwise false.

◆ GetTarget()

BaseList2D* GetTarget ( BaseDocument * doc )

Retrieves the target of the morph.

Parameters

[in] doc The document containing the morph tag.

Returns: The target of the morph. The tag owns the pointed object.

◆ SetTarget()

void SetTarget	(	CAPoseMorphTag *	tag,
		BaseDocument *	doc,
		BaseList2D *	bl
	)

Sets the target of the morph.

Parameters

[in]	tag	The morph tag containing the morph node.
[in]	doc	The document containing the morph tag.
[in]	bl	The new target of the morph.

◆ SetStrength()

void SetStrength ( Float strength )

Sets the strength of the morph.

Parameters

[in] strength The new strength of the morph.

◆ GetStrength()

Float GetStrength ( )

Retrieves the strength of the morph.

Returns: The strength of the morph.

◆ IsPostDeform()

Bool IsPostDeform ( )

Retrieves if the morph is applied at PostDeform.

Returns: Morph is post-deform mode.
