We present ACCD, an interaction technique that allows di­rect drawing of long curves on 3D shapes with a tablet display over both multiple depth layers and multiple viewpoints. ACCD reduces the number of explicit viewpoint manipu­lations by combining self-occlusion management and auto­mated camera control. As such it enables drawing on oc­cluded faces but also around a 3D shape while keeping a con­stant drawing precision. Our experimental results indicates the efficacy of ACCD over conventional techniques.
