Function Documentation

BM_mesh_intersect()

bool BM_mesh_intersect	(	BMesh *	bm,
		blender::Span< std::array< BMLoop *, 3 > >	looptris,
		int(*	test_fn )(BMFace *f, void *user_data),
		void *	user_data,
		bool	use_self,
		bool	use_separate,
		bool	use_dissolve,
		bool	use_island_connect,
		bool	use_partial_connect,
		bool	use_edge_tag,
		int	boolean_mode,
		float	eps )

Intersect tessellated faces leaving the resulting edges tagged.

Parameters

test_fn	Return value: -1: skip, 0: tree_a, 1: tree_b (use_self == false)
boolean_mode	-1: no-boolean, 0: intersection... see BMESH_ISECT_BOOLEAN_ISECT.

Returns

true if the mesh is changed (intersections cut or faces removed from boolean).
