Sirds lets you create Single Image Random Dot Stereogram (SIRDS) and Single Image Stereogram (SIS) images.
- Generate a "wall-eyed" (divergent) or "cross-eyed" (convergent) stereogram
- Customizable dimensions (resolution, observer distance, maximum depth, and eye separation)
- Hidden-surface removal
- Center to both sides method to minimize the distortion
- Oversampling to give smooth depth levels
- Stereogram viewing guide marks
- Random Dot pattern generator
- Supported depth map and pattern image file types: PNG, TIFF, JPEG, BMP, GIF, PICT, etc.
- AppleScript scripting
SIRDS or SIS is
an autostereogram which does not require any equipment to view a three-dimensional scene.
* Stereogram algorithm licensed from W.A. Steer. Visit www.techmind.org for technical details.

- Choose the "New" menu item from the "File" menu or press command - N to create a new Sirds document.
- Drop a depth map image onto a Sirds document window.
- Change the random dot color and shape, or import a pattern (or tile) image.
- Check the "Show Guide" option or press command - G to show the stereo view guide if you have trouble figuring out how deep you need to look.

when you are looking at the correct depth.
