Hand shadows, also known as shadow puppetry or shadowgraphy, involve creating various shapes and figures using your hands and fingers to cast meaningful shadows on a wall. In this work, we propose a differentiable rendering-based approach to deform hand models such that they cast a shadow consistent with a desired target image and the associated lighting configuration. We showcase the results of shadows cast by a pair of two hands and the interpolation of hand poses between two desired shadow images. We believe that this work will be a useful tool for the graphics community.Attribution 4.0 International LicenseCCS Concepts: Computing methodologies -> Rendering; Optimization; Neural NetsComputing methodologiesRenderingOptimizationNeural Nets10.2312/pg.20231279107-1082 pages
