void compute_aggr_of_coord

(

coord_t *

coord

)

Definition at line 41 of file coord.c.

static void compute_transform_function

(

coord_t *

visit

)

[static]

Compute agrregated transform function.

Base on parent's aggregated matrix if it is existed, or use transform matrix as aggregated matrix.

Definition at line 33 of file coord.c.

void coord_init	(	coord_t *	co,
		coord_t *	parent
	)

Initialize a coord object.

The object is cleared and matrix was initialized to ID. The object is be a children of specified parent.

Definition at line 86 of file coord.c.

void coord_trans_pos	(	coord_t *	co,
		co_aix *	x,
		co_aix *	y
	)

Definition at line 101 of file coord.c.

co_aix coord_trans_size	(	coord_t *	co,
		co_aix	sz
	)

Definition at line 114 of file coord.c.

static void mul_matrix	(	co_aix *	m1,
		co_aix *	m2,
		co_aix *	dst
	)			[static]

Definition at line 19 of file coord.c.

coord_t* postorder_coord_subtree	(	coord_t *	root,
		coord_t *	last
	)

Definition at line 154 of file coord.c.

coord_t* preorder_coord_subtree	(	coord_t *	root,
		coord_t *	last
	)

Note:

Coords, marked with COF_SKIP_TRIVAL (for temporary), and descendants of them will not be trivaled and the flag with be removed after skipping them.

Definition at line 128 of file coord.c.

void update_aggr_matrix

(

coord_t *

start

)

Update aggregate matrices of elements under a sub-tree.

A subtree is specified by the root of it. All elements in the subtree are effected by that changes of matrix of the subtree root.
