Re[2]: [Haskell-cafe] How to use arrays efficiently?

Thanks for help. I did some tests with UArray and it does the trick. The problem remaining is, how to implement UArray Int (Double, Double, Double)? UArray source code is far too cryptic for me.

Regards, Lauri

     pixelArray :: Array Int Color

it's boxed array which means that its elements are stored as thunks computed only when you actually use them. try UArray instead:
