You will find a CD containing two free programmes called pluri_demo_simu and pluri_demo_vario plus a set of colour images, in the pocket in the back cover of this book. These two programmes were designed to allow users to discover plurigaussian simulations by “playing” with them. The first one makes it possible to visualise simple plurigaussian simulations and to see how changes in the input parameters affect the resulting images. The second one is more technical. It illustrates the relationship between the indicator variogram and those of the underlying gaussian random functions (RFs for short) that are truncated to give the indicators. For each programme we provide a set of graded exercises showing how to run the programme and how the key parameters affect the simulated images or the indicator variograms, as the case may be.
