void GQ_Edge::splice ( GQ_Edge * b )

inline

Given the current quad edge a=this and b, splice affects the topology of the 2 quad edge rings a->org() and b->org() as follows:

if 2 rings are distinct, they will be combined.
if 2 rings are exactly the same, it will be broken into 2 separate pieces. The cuts will occur immediately after a and b in counterclockwise order. (Envision a wagon wheel with the spokes as the edges and the centre of the wheel as their common origin. For spokes (edges) a and b on the wheel, the divisions will occur between spoke a and the edge to its left, and spoke b and the edge to its left. Each of the two resulting pieces now forms a ring.)

Note that a->org() and b->org() should be equal for a splice to make sense. This method does not alter a->org() and b->org().

Definition at line 218 of file GQ_Edge.h.

void GQ_Edge::swap ( )

Swap the connecting edge

     ---          ---     |

From / TO \ | — — |

For example, if we have two triangles: b +---—+ +---—+ | /| b|\ | | _/ | L| _ | | e/| | n| ||aLnext | / | -> swap e| \ | | / | x| \ | |/ a | t| | +---—+ +---—+

GQ_Edge* GQ_Edge::sym ( )

inline

Get opposite orientation of this edge (symmetry). Returns an edge pointing in the opposite direction.

Definition at line 149 of file GQ_Edge.h.

const GQ_Edge* GQ_Edge::sym ( ) const

inline

Definition at line 150 of file GQ_Edge.h.
