With this workflow for ComfyUi you can create stereo 3d images in the red-cyan anaglyph format from ordinary flat photos.
The conversion algorithm is based on the preliminary creation of a depth map, which is inferior in quality to shooting with two cameras, but due to the high smoothing of the depth map, good results are obtained.
To view images in the anaglyph 3D format, you need a high brightness monitor and high-quality red-cyan eyeglass lenses, which is achieved today by combining several lenses widely available on the eyeglass market.
