def=adds a two-dimensional array of vertices to an existing model
Flash3DInstance..model[modelID].addVertices(vertexArray);
The format fo the vertexArray is: [[x,y,z],[x,y,z],[x,y,z]...]
&sam=
//creates an empty model, then adds three vertices and makes these define a side of the model
verts = [[0,-50,0],[50,50,0],[-50,50,0]];

myWorld.newModel("mod", "myMesh");

myWorld.model["mod"].assignSide([0,2,1], 0x0000FF, 100);
