A guessing game that implements the Shadow Mapping technique in OpenGL ES.
Usage:
Try to guess the number of spheres in the scene. Make your guess by clicking one of the four buttons with numbers on them. Every 5 correct answers will get you to a more difficult level. There is no time limit; so, take your time. You may zoom in or zoom out by using the pinch gesture.
A landscape view is available by rotating your phone or tablet. Sphere Cam button will change the view one by one over spheres in arbitrary order. Reset View button will reset the view back to the rotating view.
