46 * This example shows how to create and display a model3d-view control.
47 * The application can cycle between 3 different models, and 3 different shaders.
48 * There are two animations running, one is a rotation for the model, one is a light that
49 * goes from one side of the model to the other.
50 * There are dedicated buttons for changing the models, the shaders and pausing the animations.
51 * The animations can also be paused, resumed with the space key
52 * A double tap in the model3d-view will make zoom-in/out of the zone clicked
