    Very cool!

    Being able to generate a smooth heightfield from contours would be amazingly useful in terms of controlling where you want your mountains etc to go, how high they are and how steep.

    By 'interpolate' do you mean a gradient fill from one one colour's level to the next or is what is referred to as a 'blend' in illustrator, where you create new vector shapes that ...er..interpolate from one shape to the next. (have I answered my own question?)

    I'd like to play around with this too. If the shapes are complex, I wonder whether feathering or using an inner glow might work to blend the colours between levels?

    If we can crack this problem, then overlaying the resulting image against a faint perlian noise background would provide a nice natural 'noise' to the mountains.
