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 support ? Grand Central Dispatch support in order to generate stereograms faster 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. Visit our forum page for more samples. Instructions: ? 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, or choose one of the sample depth maps from the "Import" menu item from the "File" menu. ? 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.
