X ray effects

[phanie]

hi,
i'd like to know if there is a command or an algorithm to apply a filter (or smthg like that) in order to obtain an X ray picture.

you mean make a skeleton picture look like it is an xray? Well xrays pass through less dense material so you need to know the material densities (I suppose).
