Once analyzed the process of recording, production and distribution of 3D video, this section presents a summary of the available display systems for viewing of content produced.
At this point, it is therefore necessary to differentiate between various displays systems for stereoscopic images:
The anaglyph system for viewing stereoscopic images uses filters of complementary colors for each eye. These colors are usually red, blue or red and green.
The sense of depth is achieved when viewing two parallel images (one for each eye) with glasses having each lens of a complementary color. Thus, the projected image in red is only seen by the eye with the red lens but not the other eye, allowing the brain to interpret a third image "virtual" three-dimensional.
