there is no source available for this one (was made during dev and would almost
certainly fail to compile anyway)
but here's the snippet
var bump:BitmapData = generateFromLib("bumpsource");
var colorsource:BitmapData =
generateFromLib("colorsource");
sphere = new Sphere({radius:3000, segmentsH:10,
segmentsW:10, material:null});
(sphere as Mesh).pushback = true;
var num:NormalUVModifier = new NormalUVModifier(sphere,
bump, "av", 255);
num.update(-1.2);
num.apply(true);
var mapgen:NormalMapGenerator = new
NormalMapGenerator(sphere, 1200, 1200, bump, 4, 100);
mapgen.addOnTraceProgress(traceProgress);
mapgen.addOnTraceComplete(traceComplete);
var mat:Dot3BitmapMaterial = new
Dot3BitmapMaterial(colorsource, mapgen.normalmap, {tangentSpace:false});
(sphere as Mesh).material = mat;
maincontainer.addChild(sphere);
Prefab does all this for you...
