Marker shading is essential for communicating 3D forms in the early stages of product design. Inspired by a technique of marker shading that is widely used by designers, this study introduces ValueSphere, a novel widget for quick and easy shading in digital drawings. Using ValueSphere, the user can set the light direction, find accurate shading values, and apply them to the sketch through intuitive pen and multi-touch gestures. We utilized ValueSphere to shade various design sketches and showcase its usefulness.
