Discover cross view and maybe other tricks

The keys have the following functions:

| X |

To change the mode of stereo vision. The default mode is a cross-view mode (by squinting). The mode in parallel vision (look in the wave background) can also be used with a headset of virtual reality.

Ctrl + mouse drag

In zoom stereo view mode, there may be an offset between the two views. The Ctrl key allows, with the click-drag of the mouse, to adjust them by limiting its displacement to only one of both views.

| Z |

To change the mode of the stereo view. The default mode is a global view mode, adapted to the size of the screen (zoom Fit).
Zoom mode displays one pixel per screen pixel (100% zoom).
Since the image is often larger than the screen, it is also possible to move in the stereo view by clicking and dragging with the mouse.
Note that the browser zoom can be combined with the mouse wheel or the Ctrl + and Ctrl − shortcuts.
Finally, in 100% zoom mode, the image can be very large, and therefore long to load in memory ... patience.
