4.9 Creation of a stereo pair for the direct view
Direct view modes – cross eyed and parallel one are for evaluating 3D effect directly from the monitor screen, without any additional devices. Gotten 3D images are convenient to be posted on the Internet.

Figure 4.7. Parallel (direct view) and cross eyed viewing options
Two images (stereo pair) — a source one and the one selected from the generated frames series one appear in the main program window when choosing one of that modes from the drop-down list on the Images window.
When using the parallel method, frames of a stereo pair are located before eyes in the order they were taken — from left to right (Fig. 4.8 — а), and changing their places when the cross eyed method is chosen (Fig. 4.8 — b).

Figure 4.8. Parallel and cross eyed viewing methods
When parallel method is used, you should look "through" the picture as if you watch an infinitely distant object. The sight lines of your eyes will be almost parallel, while the accommodation should be adjusted to the actual distance to the image.
To be able to see the stereo effect in the cross eyed viewing mode, you should look at the picture that way as if there was an imaginary object before the image itself. The sight lines will intersect in this case, accommodation should be adjusted to the actual distance to the image.
The generated stereo pair can be saved on disk:
