Feasibility Study on Free Hand Geometric Modelling Using Leap Motion in VRML/X3D

Common shape modelling is usually done with virtual tools controlled by interactive or hap tic devices, which have one interface point for simulating collision between the object and the modelling tool. Shape modeling with some kind of virtual hand where several fingers deform the object was not very common since the respective devices are either too expensive or not very precise. Introduction of affordable Leap Motion device opens new prospects for free hand shape modeling. This paper is a feasibility study on using Leap Motion for shape modeling in VRML/X3D environments where virtual objects are defined by mathematical functions and hence can easily be exchanged across the internet due to their small size.
