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.
