Two channels: a correct channel for the appropriate eye along with a left channel to the still left eye. Both of those channels may be viewed simultaneously by utilizing mild-polarizing filters 90 levels off-axis from one another on two video projectors.
In interlaced video, the horizontal scan strains of every full frame are addressed like numbered consecutively and captured as two fields: an odd discipline (higher discipline) consisting in the odd-numbered strains and an excellent area (lower industry) consisting on the even-numbered lines. Analog Exhibit units reproduce Each and every body, efficiently doubling the body charge in terms of perceptible Total flicker is concerned.
Easy crimson/cyan plastic glasses present the means to check out the pictures discretely to variety a stereoscopic view from the articles.
