bool HUSD_Cvex::applyRunOverArrayElements ( HUSD_AutoWriteLock & writelock ) const

bool HUSD_Cvex::applyRunOverPrimitives ( HUSD_AutoWriteLock & writelock ) const

bool HUSD_Cvex::getIsTimeVarying ( ) const

Returns true if any attribute the CVEX has run on has many time samples.

bool HUSD_Cvex::matchFaces	(	HUSD_AutoAnyLock &	lock,
		UT_ExintArray &	matched_faces_indices,
		const UT_StringRef &	geo_prim_path,
		const UT_ExintArray *	face_indices,
		const HUSD_CvexCode &	code
	)		const

Get the faces for which the given cvex command (ie, its first int output) or a vexpression returns a non-zero value.

bool HUSD_Cvex::matchInstances	(	HUSD_AutoAnyLock &	lock,
		UT_ExintArray &	matched_instance_indices,
		const UT_StringRef &	instancer_prim_path,
		const UT_ExintArray *	point_indices,
		const HUSD_CvexCode &	code
	)		const

Get the faces for which the given cvex command (ie, its first int output) or a vexpression returns a non-zero value.

bool HUSD_Cvex::matchPrimitives	(	HUSD_AutoAnyLock &	lock,
		UT_StringArray &	matched_prims_paths,
		const HUSD_CvexCode &	code,
		HUSD_PrimTraversalDemands	demands,
		const UT_PathPattern *	pruning_pattern = `nullptr`
	)		const

Gets the primitives for which the given cvex command (ie, its first int output) or a vexpression returns a non-zero value.

bool HUSD_Cvex::partitionFaces	(	HUSD_AutoAnyLock &	lock,
		UT_Array< HUSD_FacesBucket > &	buckets,
		const UT_StringRef &	geo_prim_path,
		const UT_ExintArray *	face_indices,
		const HUSD_CvexCode &	code
	)		const

Partitions the face set specified by the geo_prim_path and face_indices, given the CVEX script whose output values are used to define buckets. When code's return type is void, all outputs are used for partitioning; otherwise, the first output of a given type is used (converted to a string keyword value). If face_indices is null, then all faces of the prim are partitioned.

bool HUSD_Cvex::partitionPrimitives	(	HUSD_AutoAnyLock &	lock,
		UT_Array< HUSD_PrimsBucket > &	buckets,
		const HUSD_PathSet &	paths,
		const HUSD_CvexCode &	code
	)		const

Partitions the primitives specified by findprims, given the CVEX script whose output values are used to define buckets. When code's return type is void, all outputs are used for partitioning; otherwise, the first output of a given type is used (converted to a string keyword value).

bool HUSD_Cvex::runOverArrayElements	(	HUSD_AutoAnyLock &	lock,
		const HUSD_PathSet &	paths,
		const UT_StringRef &	cvex_command
	)		const

Runs the CVEX script on the array attribute of USD primitives, setting their elements.

bool HUSD_Cvex::runOverPrimitives	(	HUSD_AutoAnyLock &	lock,
		const HUSD_PathSet &	paths,
		const UT_StringRef &	cvex_command
	)		const

Runs the CVEX script on the USD primitives, setting their attributes.

void HUSD_Cvex::setArraySizeHintAttrib ( const UT_StringRef & attrib_name )

Set the name of the array attibute whose length should be used as a hint about the number of array elements to run cvex on. NOTE: This is the lower bound, and the actual number may be higher than that if CVEX code references some larger array attribute.

void HUSD_Cvex::setBindingsMap ( const HUSD_CvexBindingMap * map )

Sets the cvex script bindings map (cvex parm -> usd prim attrib).

void HUSD_Cvex::setClearExistingAttribData ( bool clear_existing )

Sets a flag inticating whether or not existing attribute data should be cleared before setting a USD attribute value. Defaults to true, and gets set to false only when setting multiple tie samples through a single HUSD_Cvex object.

void HUSD_Cvex::setCwdNodeId ( int cwd_node_id )

Sets the ID of a node that executes the CVEX script. It is used for channels evaluation in VEX as well as error reporting.

void HUSD_Cvex::setDataCommand ( HUSD_CvexDataCommand * vex_geo_command )

Sets an object that processes VEX functions that modify the USD data.

void HUSD_Cvex::setDataInputs ( HUSD_CvexDataInputs * vex_geo_inputs )

Sets an object that resolves a stage based on handle, which are used in calls to VEX functions that operate on USD data (eg, primitives). Handles are strings that usually refer to LOP node inputs "opinput:0".

void HUSD_Cvex::setOpCaller ( OP_Caller * caller )

Sets the caller object that keeps track of dependencies on any node referenced with the 'op:' syntax in code.

void HUSD_Cvex::setTimeCode ( const HUSD_TimeCode & time_code )

Sets the time code at which attributes are evaluated and/or set.
