My problem was in incorrect loader. That's how i loaded my object to 3d Scene:
TransformGroup obj = new TransformGroup();
Scene s = null;
ObjectFile f = new ObjectFile ();
f.setFlags (ObjectFile.RESIZE | ObjectFile.TRIANGULATE | ObjectFile.STRIPIFY);
try{ s = f.load (obj_path+model+"\\"+model+".obj"); }catch(Exception ex) { ex.printStackTrace(); }
obj.addChild(s.getSceneGroup());
obj.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
The problem is in that row:
f.setFlags (ObjectFile.RESIZE | ObjectFile.TRIANGULATE | ObjectFile.STRIPIFY);
Flag ObjectFile.RESIZE mean that object loaded from file placed in the middle of it's height to the center of coordinate and decrease or increase size of object from it's original to range x:[-1,1]; y:[-1,1]; z:[-1,1].
But there no way to know current size of object, like width or height... Well, or i could not find in google.
