GU_API void GU_Copy::GUaddAttributesFromSourceOrTarget	(	GU_Detail *	output_geo,
		const GU_Detail *	source,
		exint *	num_source_attribs = `nullptr`,
		bool	has_transform_matrices = `false`,
		bool *	needed_transforms = `nullptr`,
		const GU_Detail *	target = `nullptr`,
		GU_CopyToPointsCache::TargetAttribInfoMap *	target_attrib_info = `nullptr`,
		GU_CopyToPointsCache::TargetAttribInfoMap *	target_group_info = `nullptr`,
		exint *	num_target_attribs = `nullptr`
	)

Adds to output_geo any missing attributes from source or target as needed. Also optionally computes what transform caches are needed for source attributes.

If an attribute is in both source and target_attrib_info/target_group_info, it will be taken from target if myCombineMethod is COPY, and will be taken from source if MULTIPLY, ADD, or SUBTRACT.

If there is only a source, e.g. if output_geo is the internal detail of a packed geometry primitive, omit target, target_attrib_info, target_group_info, and num_target_attribs.

If there is only a target, pass nullptr for source, and then num_source_attribs, has_transform_matrices, and needed_transforms will be ignored.

NOTE: num_source_attribs or num_target_attribs, if non-null, should be an array long enough to support GA_ATTRIB_VERTEX, GA_ATTRIB_POINT, and GA_ATTRIB_PRIMITIVE as indices, (3 at the moment, since they come first in GA_AttributeOwner). NOTE: needed_transforms, if non-null, should be an array of length NeededTransforms::num_needed_transforms.

	)

Uses the transforms in cache and geometry from source to create num_packed_prims packed geometry primitives referencing the same geometry. If the source groups are null, source_handle will be used to create the packed geometry primitives.

If target and the later parameters are non-null, target attributes in target_attrib_info and target_group_info will be copied from the points in target_point_list.

NOTE: This will clear output_geo if the topology has changed since the previous cook.

GU_API void GU_Copy::GUcreateVertexListAndGeometryFromSource	(	GU_Detail *	output_geo,

GU_API void GU_Copy::GUhandleTargetAttribsForPackedPrims	(	GU_Detail *	output_geo,
		GU_CopyToPointsCache *	cache,
		const bool	topology_changed,
		const bool	had_transform_matrices,
		const GU_Detail *const	target,

		GU_CopyToPointsCache::TargetAttribInfoMap &	target_attrib_info,
		GU_CopyToPointsCache::TargetAttribInfoMap &	target_group_info,
		const UT_Vector3 *const	constant_pivot
	)

This sets the packed primitive local transforms, sets P based on the translations and pivots, (i.e. it first calls GUupdatePackedPrimTransforms), then removes unnecessary attributes, adds needed attributes from target, and copies target attribute values.

NOTE: constant_pivot being null means to get pivots from the primitives.

GU_API void GU_Copy::GUremoveUnnecessaryAttribs	(	GU_Detail *	output_geo,
		const GU_Detail *	source,
		const GU_Detail *	target,
		GU_CopyToPointsCache *	cache,
		const GU_CopyToPointsCache::TargetAttribInfoMap *	target_attrib_info,

		const GU_Detail *	target,
		const bool	transform_using_more_than_P,
		const bool	allow_implicit_N,
		bool &	transforms_changed
	)

NOTE: transforms_changed must be initialized in advance to the condition of whether there are external factors that lead the transforms to need to be recomputed, e.g. the target point list changing from the previous cook.

GU_API void GU_Copy::GUupdatePackedPrimTransforms	(	GU_Detail *	output_geo,
		GU_CopyToPointsCache *	cache,
		const bool	had_transform_matrices,
		const exint	num_packed_prims,
		const UT_Vector3 *const	constant_pivot,
		UT_Interrupt *	boss = `nullptr`
	)

This sets the packed primitive local transforms, and sets P based on the translations and pivots.
