abstract = "Efficient path-planning methods are being explored along the years
to allow the movement of robots or virtual agents in planar
environments. However, there is a lot of space to improve the
quality of paths restricted to 3D surfaces, with holes and bends
for instance. This work presents a new technique for path-planning
on 3D surfaces called 3DSBVP. This path planner is based on
Boundary Value Problem (BVP), which generates potential fields
whose gradient descent represents navigation routes from any point
on the surface to a goal position. Resulting paths are smooth and
free from local minima. The 3DS-BVP works on complex surfaces of
arbitrary genus or curvature, represented by a triangle mesh,
without the need of 2D parametrizations. Our results demonstrate
that our technique can generate paths in arbitrary surfaces with
similar quality as those generated by BVP-based methods in planar
environments. Our approach can be applied in the development of
new tools to automate the navigation on 3D surfaces, like the
camera control in the exploratory visualization of 3D models.",
