Instructions for setting up stereo panorama wall/floor image
Here are some photoshop files and illustrated instructions for setting up an image of a basic flat wall with a steeply foreshortened 3D floor plane at the bottom. Everyone should use this as a basic template for the images for the stereo panorama, adding their own windows, doors, portals, etc.
1. Open floorWallMask.psd. This file consists of a blank background, and one layer that contains a mask for your stereo image.

2. Select the background layer and create your wall and floor image.
3. Save your image under a new name.
4. Select Layer/Flatten Image.

5. Select Filter/Distort/Displace.

6. Set 'Horizontal Scale' to -16, and 'Vertical Scale' to 0. Click OK.

8. This is your left-eye image. Save it with a new name (ImageNameL.psd).
9. Reopen your unflattened image.
10. Flatten it again.
11. Select Filter/Distort/Displace.
12. Set 'Horizontal Scale to 16 and 'Vertical Scale' to 0.
