Function Documentation

bm_edge_calc_rotate_cost()

float bm_edge_calc_rotate_cost ( const BMEdge * e )

static

Edge length is just a way of ordering that's independent of order in the edges argument, we could use some other method since ideally all edges will be rotated, this just happens to be simple to calculate.

bm_edge_rotate_is_boundary()

bool bm_edge_rotate_is_boundary ( const BMEdge * e )

static

Check if this edge is a boundary: Are more than one of the connected faces edges rotating too?

bm_rotate_edges_shared()

void bm_rotate_edges_shared ( BMesh * bm, BMOperator * op, short check_flag, const bool use_ccw, const int edges_len )

static

Rotate edges where edges share faces, edges which could not rotate need to be re-considered after neighbors are rotated.

void bm_rotate_edges_simple ( BMesh * bm, BMOperator * op, const short check_flag, const bool use_ccw )

Rotate edges where every edge has its own faces (we can rotate in any order).
