P3D Pure Anaglyph Definition

Normally one could forget the Pure Anaglyphs.
Gray Anaglyphs are better in every case!

So you could ask: Why are Pure Anaglyphs used?
I guess since they are the most simple ones! Another reason
may be that not many people know how to generate
Gray Red-Green, Gray Red-Blue and Color Red-Green,
Color Red-Blue Anaglyphs.

The following two kinds of Pure Anaglyphs are possible:

Red-Green:
L image grayscale --> R channel of anaglyph
R image grayscale --> G channel of anaglyph
B channel of anaglyph is always zero. That is the reason why these
anaglyps are so yellow!

Red-Blue:
L image grayscale --> R channel of anaglyph
R image grayscale --> B channel of anaglyph
G channel of anaglyph is always zero. That is the reason why these
anaglyps are so purple!

A Red-Cyan Pure Anaglyph is not possible, as it is the same as
the Gray Red-Cyan Anaglyph!

When I developed Stereoscope Applet my biggest problem was to
implement the algorithms for Gray Red-Green, Gray Red-Blue,
Color Red-Green and Color Red-Blue. If I remember it correctly
these modes are implemented wrong in DepthCharge.
