Q My final nodes are distorted -- what do I do?
A Here are a few possibilities:
1. fovy is set incorrectly:
Stitch your image with the verbose switch included and some clearance on the
fovy. For example, stitch ...
When you do this, the stitch command will calculate the correlation at all
angles from 87 to 107. Then, when it is done it will say
2. There is height and/or width distortion.
Try taking the outHeight and outWidth commands out of the stitch script and rerun. Load the resulting file into Adobe PhotoShop or some other graphics package and look at its size in pixels. Then, rerun all of your scripts setting outWidth to the width found in pixels and set outHeight to the number closest to the height in pixels that is divisible by 24 (assuming that you are dicing 1x24).
3. vPanRange in msnm is set incorrectly.
This should be a little less than half of your fovy. For example, if fovy was set to 96, vPanrange should be 45. This is a switch in msnm - vPanRange 45 -45. Alternatively, the proper vPanAngle should come out of the stitch command with the verbose switch on. It will be labeled as cylAngle. If your cylAngle is 90, vPanRange is 45 -45.
