This demo shows some postprocessing tricks and techniques to achieve cool effects applied to a flat simple textured background. There is no geometry of any kind but a quad screen aligned.

Everything is rendered under OpenGL ES 2.0.

The app is an updated and refreshed new compilation under Android Studio of my previous app "OpenGL ES 2.0 demo" under a new keystore featuring new effects and hopefully no more weird and random crashes due to a very old android compilation of the previous version.

HOW TO USE:

Touch the screen with one finger to move the light pos.

While touching the screen with one finger touch with another the right side of the screen to change the effect.

Do the same but touching the left side instead to change the background texture.
