DESCRIPTION:We present a new method for first-person sketch-based editing
  of terrain models. As in usual artistic pictures\, the input sketch depic
 ts complex silhouettes with cups and T-junctions\, which typically corresp
 ond to non-planar curves in 3D. After analyzing depth constraints in the s
 ketch based on perceptual cues\, our method best matches the sketched silh
 ouettes with silhouettes or ridges of the input terrain. A specific defor
 mation algorithm is then applied to the terrain\, enabling it to exactly m
 atch the sketch from the given perspective view\, while insuring that none
  of the user-defined silhouettes is hidden by another part of the terrain
 . As our results show\, this method enables users to easily personalize an
  existing terrain\, while preserving its plausibility and style.
