BM_face_split_edgenet()

bool BM_face_split_edgenet	(	BMesh *	bm,
		BMFace *	f,
		BMEdge **	edge_net,
		int	edge_net_len,
		blender::Vector< BMFace * > *	r_face_arr )

Splits a face into many smaller faces defined by an edge-net. handle customdata and degenerate cases.

• Isolated holes or unsupported face configurations, will be ignored.
• Customdata calculations aren't efficient (need to calculate weights for each vert).

BM_face_split_edgenet_connect_islands()

bool BM_face_split_edgenet_connect_islands	(	BMesh *	bm,
		BMFace *	f,
		BMEdge **	edge_net_init,
		uint	edge_net_init_len,
		bool	use_partial_connect,
		struct MemArena *	mem_arena,
		BMEdge ***	r_edge_net_new,
		uint *	r_edge_net_new_len )

For when the edge-net has holes in it-this connects them.

Parameters

use_partial_connect

Support for handling islands connected by only a single edge,

Note

that this is quite slow so avoid using where possible.

Parameters

mem_arena

Avoids many small allocations & should be cleared after each use. take care since edge_net_new is stored in r_edge_net_new.
