Generate anaglyph from 3-D plot
I=ANAVIEW generates the anaglyph version of the 3-D plot in the
current axis.
The left-right view disparity is computed assuming that the
distance from the camera position to the camera target is of one
meter, that the two eyes have distance of 0.1 meters and that the
screen is at a distance of 1 meter from the observer.
Target and image distance can be changed (see options
below). Generally speaking:
+ Increasing/decreasing the target distance will move the object
away/closer to the observer.
+ The target distance is represented relative to the screen
distance. So increasing/decreasing the screen distance while
keeping the object distance and the true distance to the screen
constant, will make the object to appear closer/farther.
+ Object points that are farther/closer than the screen will
appear behind/above the screen.
All these operations do not change the amount of perspective
distortion as the object is scaled up/down and the focal length
stays the same. The focal length can also be changed (see options
below). A smaller focal length will cause the object to appear
deeper.
The following option-value pairs are supported:
'TargetDistance' [1]
Distance of camera target. The closer, the more pronounced the
disparity.
'ImageDistance' [1]
Distance of monitor surface. The closer, the deeper the
objects are pushed.
'ScaleFocal' [1]
Multiply camera focal length by this factor, while moving
closer/farther to the object to keep the target of the same
size. This step is applied before setting the target and
screen distances.
'Background' [0.1]
Intensity of the background tone (green channel), in the 0-1
range.
