This does the trick. It is a bit of a hack but it works. If you know
of a better/faster way to actually access the grouped Vertex please
let me know.
var o3d:MovieMesh = event.target as MovieMesh;
var vert:Vector.<Number> = o3d.vertices;
var length:int = vert.length;
var force:int = 0.003;
var vertexHash:Dictionary = new Dictionary();
var key:String;
var i:int;
for( i = 0; i < length; i +=3)
{
var v:Vertex = new Vertex(vert[i],vert[i+1], vert[i+2]);
key= vert[i]+" "+vert[i+1]+" "+vert[i+2];
if(vertexHash[key] == undefined)
{
v.x += Math.sin(force + i/3);
v.y += Math.sin(force + i/3);
v.z += Math.sin(force + i/3);
vertexHash[key] = v;
}
}
for( i = 0; i < length; i +=3)
{
key = vert[i]+" "+vert[i+1]+" "+vert[i+2];
if(vertexHash[key] != undefined)
{
var v3:Vertex = vertexHash[key] as Vertex;
vert[i] = v3.x;
vert[i+1] = v3.y;
vert[i+2] = v3.z;
}
}
