3D red-blue glases usage eye safety.1.
It is recommended to reduce time of usage of 3D red-blue glases by 1-2 hours/day because the color separation for each eye is not natural way of view. The brain can not detect true color when left and right eye signals different colors for the same thing.
It is also recommended to swap red-blue filter between eye time to time (one time per hour) and swap red-blue filter after usage for 1-2 minutes to recover normal color detection faster.
2.
It is also possible to turn true color image into "two color + black" separation (not in red-cyan separation), to do that you need:
a) xor 3d party OpenGL anaglyh driver (there is no the free driver for windows Vista and up)
b) xor change FG source and recompile OSG-anaglyph output method
In both cases you need turn settings of anaglyph output in the following way
<AnaglyphOutput>
<!-- Red / Blue custom color matrix -->
<CustomLeftMatrix m00="0.2126" m01="0.7152" m02="0.0722" m10="0" m11="0" m12="0" m20="0" m21="0" m22="0" />
<CustomRightMatrix m00="0" m01="0" m02="0" m10="0" m11="0" m12="0" m20="0.2126" m21="0.7152" m22="0.0722" />
</AnaglyphOutput>
<!--
RGB to YUV (grayscale)
PAL: Y = 0.299 * R + 0.587 * G + 0.114 * B;
HD: Y = 0.2126 * R + 0.7152 * G + 0.0722 * B;
-->
mXY means
m - matrix
X - color that will be displayed on screen in result
Y - color that game was going to display
0-red
1-green
2-blue
example
true color image
"two color + black" separation
3. future of 3D display
One of the posible way is "3D helmet" with correct optical scheme (because there are many LCD displays are being producing for smartphones etc)
there are no the devices in current market as i know
PS:
New 3D red-blue settings to feel real YAK panel at 500mm distance
<osg-displaysettings>
<!-- 0.015-0.15 FOV 65, eye to screen dist 250mm -->
<eye-separation type="float">0.015</eye-separation>
<screen-distance type="float">0.15</screen-distance>
<stereo-mode type="string">ANAGLYPHIC</stereo-mode>
</osg-displaysettings>
