Hi
Note:
The 2D to 3D anaglyph produces a pseudo stereo effect making the resultant anaglyph image appear to be behind the plane of the frame (or any text if present.) The image itself remains in 2D.
The amount of plane shift depends on the separation of the Red and Cyan images. With standard anaglyph glasses (Red lens over the left eye,) moving the Cyan image to the right pushes the image behind the frame. The VP export setup "Anaglyph Image Red-Cyan" does this.
If you export as "Anaglyph Image Cyan-Red" The Red image is pushed to the right making the anaglyph appear to be in front of the frame or text..
Note that If your anaglyph glasses has the Red lens over the right eye, the effect is reversed.
The intensity of the pseudo 3D effect is dependant on the separation of the Red and Cyan images, the more the separation the greater the 3D effect. Here's a typical pseudo 3D image created with a graphics program.......

Using anaglyph glases you will see the 2D image is behind the text
Unfortunately there is no user control for this separation as VP creates it during export. In practice it is quite small and so sadly the 3D effect is not particularly striking.
