Function Documentation

BKE_mesh_foreach_mapped_edge()

void BKE_mesh_foreach_mapped_edge	(	Mesh *	mesh,
		int	tot_edges,
		void(*	func )(void *user_data, int index, const float v0co[3], const float v1co[3]),
		void *	user_data )

Copied from #cdDM_foreachMappedEdge.

Parameters

tot_edges

Number of original edges. Used to avoid calling the callback with invalid edge indices.
