By covering the fisheye with a translucent
globe (60cm in diameter), the planetarium can be transformed into a versatile
educational tool.
The images need to be modified. An
enough good transformation consists in transforming the rectangular image
in polar coordiantes through the "rectangular to polar" filter like in
The GIMP.
Source image:
You have to transform it into a
square image before applying the filter.
Instead of just taking a part of the
image to get a correct fisheye view, you'll use there the entire image.
In the end you have to revert it left/right because now you'll see the
result from the outside of the projection system.
