Abstract

With growing popularity of online 3D shape databases, the problem of navigation
and remote visualisation of large 3D shape models in such repositories is
gaining prominence. While some recent work has focused on automatically
computing the best view(s) of a given model, little attention has been given to
the problem's dynamic counterpart - best fly. In this paper, we propose a
solution to this problem that extends on previous best view methods. Given a
shape, we use its best views to compute a path on its viewsphere which acts as
a trajectory for a virtual camera pointing at the object. We then use the
model's geometric properties to determine the speed and zoom of the camera
along the path.
