Interlaced Stereo Images
|Images with stereo shadows, such as this one, can be prepared by the
Andromeda Shadow Filter, which I am primarily reponsible for.|
Interlaced format stereo has some advantages and some disadvantages over Anaglyph stereo
- Color quality is unaffected
- Viewing requires shutter glasses, and some kind of driver hardware, and willingness to endure interlaced displays.. Prices
start at $100. The particular hardware I have is a 3D-Photomaster, whose 3d glasses connect externally, between the
video card and monitor.
Tips for Preparing Interlaced Images for web viewing. (using Adobe Photoshop)
- Load left and right images. Select the left image. Paste into the Right image as a new layer.
- Scale the images to the desired final size. You can't scale the image after it is interlaced.
- Set the layer opacity to 50%, use the move tool to exactly align some part of the image pair.
- Set the opacity of the layer back to 100%
- Use Filter Factory (under plugins/synthetic) to create an "odd line" filter, defined by a=(y&1)*a. Filter. (or if you're lazy,
download my FFactory odd-line filter for the PC here)
- Flatten the image. Make sure you are viewing the image at 100% size.
- Convert to indexed color/GIF or JPEG and save.
