Hello Rock,
I just tried your double vision problem and it is easy to do with video post
and a transparancy mask. No IPAS needed.
– Decide the shape and size of the central area of normal
vision and build a transparancy mask. Make it pure white in
the middle and 50% grey outside the middle. Make it the same
resolution as your rendered images and things will be
easier. You probably want a soft edge between the two
areas. This is very easy to do in a program like Photoshop.
The image can be saved as an 8-bit GIF.
– Render an image (or animation) to be used to demonstrate
the effect.
– In Video Post, create two entries in the queue, both with
the same source image (or animation) used as a bitmap.
In the first entry, click on OFFSETS and add a little
offset. I used an X-offset of 4 with a 256×256 test
image.
In the second entry, use a zero offset. Click on the
second entry's ALPHA slot and set your transparancy
mask image as an RGB INTENSITY MASK.
The Video Post queue should now look like this:
IMAGE.TGA
IMAGE.TGA RMask/I
When you render your image (or animation), it will have a normal image in the
center and a double image outside.
There are probably many ways to do this, but this is the first one I thought
of. Good luck!

Great tip on the double vision thing John.

Just my kind of fun! (Yikes, can you imagine having vision like that? I thank
God for eyes that work.)

Here's a possibility.
Render the clear image or animation and use it as a background image.
Map that same image to a transparent, flat object larger than your scene and
scale the mapping to give the double vision effect.
Place a flat matte object to clear the central 30 degree viewing area by
allowing the background to show through.
Haven't tried it myself, but……
Good luck
