The interface consists on a picture's canvas-like screen, where the user sketches silhouettes of mountains, as he would do if drawing mountains on a piece of paper. Realistic results are achieved by combining copies of the example terrain in such a manner that matches the sketched silhouette. We use Digital Elevation Models (DEM) of real world terrains as source data, and a weighted sum function to continually combine the heights.CR CategoriesI.3.7 [Computer Graphics]Three Dimensional Graphics and RealismRadiosityKeywordsterrainmodelingDEMexamplebasedfirst personsilhouette10.1145/2487381.248738261-68
