  abstract = {Modern line rendering systems can create high-quality
              illustrations. However, the interaction possible with such systems
              is often limited to selecting an appropriate viewpoint and
              applying certain line styles to the entire model. NPR Lenses are a
              new non-photorealistic rendering tool, that allows integrated
              distortions in 3D with common 2D interaction techniques. NPR
              Lenses support local adjustments to rendered 3D line-drawings
              while being view-aligned and still supporting the independent
              adjustment of the 3D scene.},
