I have Object3D in skybox background. While I move camera then Ojbect3D move.
How to check event touch on Object3D miss?
			
			
			
				I don't get the question... ???
			
			
			
				while touch on screen check width position of Object3D? 
			
			
			
				Do you mean to "pick" a object3d?
if so ,search mouse pick in forum for more details
set the collision mode in your object3d and then 
SimpleVector simpleVector = Interact2D.reproject2D3DWS(
				camera, frameBuffer, touchX, touchY).normalize();
		Object[] ii = world.calcMinDistanceAndObject3D(camera
				.getPosition(), simpleVector, 10000);
in ii[1] that's the object3d which be touched or null if nothing is been touched.
