    (irst0 something 4orth co6ering: 4hat is a height map;

    t2s a gray scale image that uses tonal 6alues from 4hite to 3lack to determine the height of that image0 or an image the height map 4ill 3e used 4ith. (or all height maps the highest point is 4hite and the lo4est 3lack. t can 3e used in Photoshop0 3ut also in 7+ applications like 7+s Ma5 or Maya < among others = used as a 23ump map2 or 2height map2 and also a 2displacement map2.

    ere2s some 6ery 3asic illustrations. All these use the first gray scale image. (irst some test in Photoshopand the t4o 6ersions in perspecti6e are in 7+ma5 rendered to sho4 the polygon density. 21hite is igh2

    !o4 4hat you can do in Photoshop0 using (ilters. 1e 4ill use *ighting Effects and Em3oss in this tutorial0 3ut it2s encouraged that you try the others and play 4ith the settings as you might like the results and it can effect ho4 your map turns out > you might disco6er a ne4 techni?ue@ f this is all ne4 to you0 then  suggest try playing around and e5perimenting 4ith 6arious settings

    eight maps are also used to create 2normal maps2 4hich are used to define detail on a lo4 polygon model for use in 6ideo games.  4on2t go into detail in this tutorial0 3ut you can find a definition here and a tutorial here . t2s used to large effect on most ne4 games like "ears of 1ar 0 Mass Effect0 Army of %4o and Medal of onour0 to name a fe40 4ho all use just one application 'nreal Engine > 3ut there are may others.

    -ou can get a Photoshop plugin to help create a normal map here 4hich uses grey scale information > aheight map. < though it must 3e said that not all normal maps are created from a grey scale image0 some are created from high polygon models =
