/*
|
||||
* This example illustrates the work of different callbacks of events from mouse
|
||||
* and keyboard.
|
||||
*
|
||||
* Next tests are available:
|
||||
* 1. All animations of scene will stop on mouse click on the background.
|
||||
* 2. Clicking of any object on scene causes stop of its movement, but if click on
|
||||
* the moon while it is in front of a planet will stop them both.
|
||||
* 3. Camera position can be changed by pressing 'down' or 'up' key. Position of
|
||||
* the camera changes in the respective direction.
|
||||
* 4. The 'n' key pressing returns camera to its default position.
|
||||
* 5. One of four types of vertex assembly of planet could be chosen by clicking on
|
||||
* a number from 1 to 4 on keyboard.
|
||||
|
||||
* Compile with:
|
||||
* gcc -o evas-3d-moon-space evas-3d-moon-space.c -g `pkg-config --libs --cflags evas ecore ecore-evas eo` -lm
