3D Interface
-
-
-This is the prototype of a 3D interface. You can move the camera with the arrow
-keys of your keyboard, and change the angle of the camera by dragging and
-dropping the scene around it (you can also use your numpad, 2 to look lower, 8
-to look higher, 4 to look on the left and 6 to look on the right, but if you're
-more comfortable with non-numpad keys, you can also use i for up, j for left, k
-for down, and l for right).
-
-
-
-Recommended views are displayed with a transparent red arrow. They disappear
-when you come closer to them, and you can automatically move to them by
-clicking on them. You can reset the camera at anytime by clicking on the reset
-button.
