/**
* Example of setting up an animated Evas-3D scene with lighting and anti-aliasing.
*
* This example illustrates use of shadows, callbacks(clicked, collision),
* technic of the billboard and post proccesing render with anti-aliasing.
*
* Model and cube are clickable. Model detects collision with sphere.
* Cube detects collision with sphere, model and cone. Model and cude are moveable.
* @see evas_canvas3d_scene_shadows_enable_set(Eina_Bool _shadows_enabled)
* @see evas_canvas3d_object_callback_register
* @see evas_canvas3d_billboard_set/get
* @see evas_object_anti_alias_set/get
*
* Control keys and description:
* 'w'/'s' key to move up/down object;
* 'a'/'d' key to move left/right object;
* 'q'/'e' key to move near/far object;
* '1'/'2' key to change kind of node - billboard/normal model\n");
* '3'/'4' key to enable/disable post proccesing render;
* '5'/'6' key to enable/disable shadow effect;
* Up/Down key to change position of camera;
* 'i' key to return initial view of scene;
