[Bf-committers] to Ton: Winged vertex extrude?

[joeedh]

Hi.  I have almost finished winged vertex extrude.  However. . .do you 
want it?  I mean, I've spent hours working on this stupid thing, and 
written about a half-dozen new functions, but I'm still wondering if 
this is something that would be included when I finish it.

Winged extrusion is a very complicated thing, especially with the 
current EditMesh implementation.  Vertex extrusion works by:

1. Convert the faces surrounding a vertex to triangles.
2. Split all the edges surrounding the vertex, to make a kind of circle.
3. Make faces between the split edges and the vert.

(wow, it sounds so simple when put like that. .  .my brain feels fried).

Edge extrusion, which I havn't started yet, would work similarily to 
this.  Oh, and I've had to add 'adjedges' and 'adjfaces' lists to the 
EditVert structure, that stores the surrounding edges and faces for each 
vert.
