Options

Options are accessible from the Tools menu, following the standard "Tools / Options" pattern common to many applications. Most options are quite self explanatory, however, some details need to be supplied also:

• The Maximum number of threads for all the calculations is the number of auxiliary threads that will be used by NDunes when performing some long calculation task (for instance calculating ambient occlusion for Soils, or calculating a global illumination solution for Geometries). If you do wish to keep a few CPU power for doing something else during this period, you may wish to reduce that number of threads to your computer's number minus one or two.
• The Maximum number of threads for the landscape is the number of auxiliary threads dedicated to updating the main view of NDunes. These threads perform Terrains calculations, they seed Plants and are in charge of all other calculations needed for a frame to be displayed. The more the better and the faster NDunes will react to changes. However, for the same reason as detailed above, you may wish to share this power with some other applications, hence the possibility here to reduce the value.
