Anaglyph (from gr. anagliphos – relief) – is the method of stereo visualization which consists of coloring two frames of a stereo pair into “supplementary” colors (e.g. one frame is red, another one is cyan). When viewing the image through anaglyph glasses, each eye perceives only one frame. Anaglyph glasses is shown on the following picture (red for the left eye, cyan – for the right).

In StereoTracer there are three modes of the anaglyph image generation: Grayscale, Sub-color, and Color. You can change frame preview mode via selection menu (see pic. 4.6).

Figure 4.6. Selection list of preview modes.

The usage of the anaglyph mode is possible only if there are generated frames in the images list. The anaglyph image is created from the first generated frame and one selected frame from the sequence. It is possible to choose the anaglyph mode by choosing the corresponding element of the drop-down list on the Images window.

The generated anaglyph image can be saved on your disk:

Menu command: Image | Save current view

Toolbar button on the Images window:

Note: The quality of an anaglyph image depends on the original source photo colors. So, in some cases the Color anaglyph mode will give the excellent result, but in the case when original photos contains a lot of red or blue colors it would be better to use Sub-color or Grayscale mode.
