Direct drawing on 3D shapes with automated camera control
Michaël Ortega, Thomas Vincent · 2014
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.
