Just encase anyone else is going down this path....
Wasn't so bad once I traced out the faces, vertices and uvs of a plane.
var p:Plane = new Plane();
p.segmentsW = 1;
p.segmentsH = 1;
p.width = 400;
p.height = 400;
//view.scene.addChild(p);
for each (var v:Vertex in p.vertices)
{
trace(v);
}
trace("");
trace("faces = " + p.faces.length );
trace("");
for each (var f:Face in p.faces)
{
trace(f);
trace(f.v0);
trace(f.v1);
trace(f.v2);
trace(f.uv0);
trace(f.uv1);
trace(f.uv2);
trace("");
}
m = new Mesh()
view.scene.addChild(m);
var f1v0:Vertex = new Vertex(-200,-200,0);
var f1v1:Vertex = new Vertex(200,-200,0);
var f1v2:Vertex = new Vertex(-200,200,0);
var f1:Face = new Face(f1v0,f1v1,f1v2);
m.addFace(f1);
