We present a new method for first-person sketch-based editing of terrain models. As in usual artistic pictures, the input sketch depicts complex silhouettes with cups and T-junctions, which typically correspond to non-planar curves in 3D. After analyzing depth constraints in the sketch based on perceptual cues, our method best matches the sketched silhouettes with silhouettes or ridges of the input terrain. A specific deformation algorithm is then applied to the terrain, enabling it to exactly match 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.
