02 When to use A dis­place­ment MAP

- Belgium · Iceland

Dis­place­ment maps are a hugely pow­er­ful tech­nique as they can in­tu­itively al­low model de­tail to be added with a sim­ple greyscale im­age. A per­fect ex­am­ple is when they are used as a sim­ple method of cre­at­ing the height data for a land­scape. As dis­place­ment maps (also some­times known as height maps) are mod­i­fy­ing the un­der­ly­ing ge­om­e­try, they need higher-res­o­lu­tion meshes to work with than bump maps which can make them slower to work with, but they can pro­duce stun­ning re­sults.
