Here is close as I have gotten: Setup:
View.scene contains one child "ObjectContainer3D". The one ObjectContainer3D has one child "Object3D". I have attached the mouse event to the nested "Object3D". I am trying to dynamically create a sphere and put in in the View.scene.addChild(sphere). and then move it to the location of where I click the mouse on the Object3D nested inside the ObjectContainer3D. I did the following conversion from Away3D 3.0.0 to Away3Dlite and it does not work as expected. //translate var m:Matrix3D = o3d.transform.matrix3D.clone(); // inner object (Object3D) var m2:Matrix3D = objcont.transform.matrix3D.clone(); // outer object (ObjectContainer3D) m.append(m2); m.invert(); var v2:Vector3D = m.transformVector(event.scenePosition); sphr.x = v2.x; sphr.y = v2.y; sphr.z = v2.z; Any help would be much appreciated.
