In this paper we propose a new and improved implicit
vector field surface representation to perform mesh fusion
in the reconstruction process of 3D objects from scanned
data. This new representation is an extension of the
implicit scalar field distance function of a mesh. We show
our new vector field function is more accurate than the
classic scalar field function by comparing both
representations with an error metric evaluation. We adapt
the fusion process previously performed on the scalar
representation to this new implicit vector field function.
The Marching Cube triangulation algorithm is also
adapted to our new vector representation to correctly
reconstruct the resulting explicit surface after fusion.
Results show that using this new vector field
representation, our mesh fusion and mesh triangulation
algorithm designs outperform the previous processes
based on the implicit scalar field function representation.
