Thanks a lot Roger for your time. Unfortunately the cloudy structure is still 2D. My problem is not how to insert a 2D plot in a 3D graphics (as you showed very nicely) but rather how I construct mathematically an actual 3D structure that looks like a cloud. Is there any algorithm producing a distribution of points (x,y,z) (maybe based on a random number generator) or a continuous surface f(x),f(y),f(z) resembling that of a cloud e.g. http://www.google.com/imgres?q=weather+clouds&num=10&um=1&hl=en&client=ubuntu&hs=DC3&channel=fs&gl=uk&biw=1440&bih=703&tbm=isch&tbnid=Uj8m6td-SInqIM:&imgrefurl=http://www.weatherreport.com/Local-weather-forecasts-Cloud-Reading.asp&docid=XlYR6VdwaOlxJM&w=800&h=600&ei=aFN8Tqi7Foy10QWaqeUC&zoom=1&iact=hc&vpx=192&vpy=194&dur=9130&hovh=194&hovw=259&tx=118&ty=116&sqi=2&page=1&tbnh=152&tbnw3&start=0&ndsp=18&ved=1t:429,r:0,s:0 Thanks a lot, Dimitris
