Detailed Description

This class is used during joint optimization or restructuring to store the table of interim joint computations.

That is to say, this class provides an temporary data store for three tables of matrices per each EggJointPointer per frame.

Constructor & Destructor Documentation

◆ EggCharacterDb()

EggCharacterDb::EggCharacterDb ( )

Constructs a database for storing the interim work for the indicated EggCharacterData.

The parameter max_ram_mb indicates the maximum amount of RAM (in MB) that the database should consume; if it the database would roughly fit within this limit, it will be stored in RAM; otherwise, it will be written to disk (if Berkeley DB is available).

Member Function Documentation

◆ get_matrix()

bool EggCharacterDb::get_matrix	(	const EggJointPointer *	joint,
		TableType	type,
		int	frame,
		LMatrix4d &	mat
	)		const

Looks up the data for the indicated joint, type, and frame, and fills it in result (and returns true) if it is found.

Returns false if this data has not been stored in the database.

Definition at line 68 of file eggCharacterDb.cxx.

◆ set_matrix()

void EggCharacterDb::set_matrix	(	const EggJointPointer *	joint,
		TableType	type,
		int	frame,
		const LMatrix4d &	mat
	)

Stores the matrix for the indicated joint, type, and frame in the database.

It is an error to call this more than once for any given key combination (not for any technical reason, but because we don't expect this to happen).
