Video game designers can use this sketching interface system to create terrain. The designer draws ‘the silhouette, spine and bounding curves of both extruding (hills and mountains) and embedding landforms (river courses and canyons).’ The system then transforms the sketch into a realistic 3D landscape.
‘Terrain is interactively generated to match the sketched constraints using multiresolution surface deformation. In addition, the wavelet noise characteristics of silhouette strokes are propagated to the surrounding terrain. With terrain sketching users can interactively create or modify landscapes incorporating varied and complex landforms.’
