The first viable LCD monitor for stereographics display is made by Zalman and costs about $300:  [http://www.zalman.co.kr/eng/product/product_read.asp?idx=219 Zalman ZM-M220W]
This Stereo mode works with cheap polarization glasses (the same as those you wear in a cinema when watching 3D movies like "Avatar") and requires a special monitor which has alternatingly polarized horizontal lines. If e.g. the odd lines of the monitor display the picture for the left eye, and the even lines display the picture for the right eye, the brain stitches the images together which results in the impression of a 3D scene. See also http://en.wikipedia.org/wiki/Polarized_3D_system.


The attributes for this monitor have been tested and [http://www.pymolwiki.org/index.php/Stereo_3D_Display_Options#One_Piece_Multi-layer_LCD_Displays described rather extensively by Warren DeLano] on the PyMOL site. Please read it for important details and suggested purchasing sources.

The following describes specifically how to get this to work with coot on Mac OS X, but the instructions should be generalizable to linux and Windoze. The beauty of this is that it is platform-independent and apparently works with pretty much any hardware (PC, mac, etc) and operating system.

== Invoking Zalman Stereo mode in COOT ==
== Invoking Zalman Stereo mode in COOT ==


Make sure "Hardware Stereo" is turned '''off'''.
Use the Draw > Stereo menu to select Zalman Stereo.


As of 0.6-pre-1 (revision 2223), you can use the Draw > Stereo menu to select Zalman Stereo.  On earlier versions, there is no button for Zalman stereo mode.  Instead, open up a scripting window, and issue the scheme command


(zalman-stereo-mode)
== Useful buttons ==


or else the python command
Customize your toolbar (the bar directly above the graphics window)! By default this only has the "Display Manager" button. Do this by right-clicking an empty part of that toolbar and then "Manage buttons (add/delete button)". There, select "Zalman Stereo/mono" and "Swap Stereo".
 
zalman_stereo_mode()
 
and you should then see a double image that looks like this:
 
[[Image:Double.png]]
 
When you put on the glasses, you should see a single image, in 3D stereo.
 
If things look weird, the image might be backwards, in which case, try moving the Coot window down one pixel (just move it around a bit until it looks right).
 
To get back to mono mode, try
 
(mono-mode)
 
or
 
mono_mode()
 
== Some Potentially Useful Scripts and Tweaks ==
 
=== Crank Up Font Size===
 
;; The font needs to be cranked up to be visible in stereo
(set-font-size 3)
 
=== For Zalman to the left of main display ===
 
If your monitor is to the right, you will have to adjust X values appropriately
 
;; Specific for Zalman monitor set to the left of eg MacBook Air
;;
;; These should be even numbers to keep the stereo
;; the right way around
(set-graphics-window-position 0 0)
(set-graphics-window-size 1680 1050)
;; Make these subsidiary windows appear on the right-hand monitor
(set-model-fit-refine-dialog-position 1900 0)
(set-delete-dialog-position 1700 50)
(set-go-to-atom-window-position 1847 67)
=== Customized Menu for Zalman Monitor ===
<pre>
;; Customize menu bar for Zalman monitor
(let ((menu (coot-menubar-menu "Zalman")))
  (add-simple-coot-menu-menuitem
  menu "Zalman Stereo ON"
  (lambda ()
(zalman-stereo-mode)))
  (add-simple-coot-menu-menuitem
  menu "Zalman Stereo OFF"
  (lambda ()
(mono-mode)))
  (add-simple-coot-menu-menuitem
  menu "Zalman Full-Screen"
  (lambda ()
(set-graphics-window-position 0 0)(set-graphics-window-size 1680 1050))))
 
</pre>
 
=== Customized Key Bindings to Toggle Stereo on and Off ===
 
Replace the keys with whatever ones you prefer.
 
<pre>
 
;; Toggle Zalman Stereo mode
    ;; bind the S (shift-s) key to get Stereo
    (add-key-binding "Zalman Stereo" "S" zalman-stereo-mode)
    ;; bind the M (shift-m) key to get Mono
    (add-key-binding "Undo Zalman Stereo" "M" mono-mode)
 
</pre>
 
===Inverted Stereo?===
 
In general, if the image is inverted, just move the window up or down 1
pixel.
 
This is painful if you maximized the window (which is what I usually do). Is there a scriptable
way? --[[User:Kay|Kay]] 11:17, 28 February 2011 (CET)
