OpenGL ES 2.0 Effects Demo

Shows several interactive graphical effects applied on top of a flat texture.

This demo shows some postprocessing tricks and techniques to achieve cool interactive effects applied to a flat simple textured background.

There is no geometry of any kind but a quad screen aligned and only two textures shared among all the effects, one for the flat background and another one enconding the wavy normals. All the rest is fully procedural.

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 to move the light pos.

Use the blue arrow to change background.

Use the red arrow to change the effect.
