This position paper presents the current state of the art on 3D dataset navigation and 3D model retrieval. We discuss a number of challenges we consider as the main points to be tackled for developing effective 3D object exploration systems.Computer Graphics [I.3.6]Methodology and Techniques10.2312/3dor.201610819-12
