FastRBFTM software enables surfaces to automatically be fitted to
point cloud data. A point
cloud is compactly represented by a signed distance function
which is smooth and continuous.
Accuracy may be specified
globally or locally
Normals may be specified with
the point cloud data to further constrain the fitted surface
A unique interpolant that
minimises a surface-energy functional is fitted with
FastRBFTM
A surface mesh can be constructed at any desired resolution from the RBF representation
Mesh optimisation produces
uniform facets of good aspect ratio (small and elongated triangles are
avoided)
Manifold surface
guaranteed
Mesh can be clipped at specified
bounding planes
Mesh can be closed at specified
bounding planes (watertight surface)
Noisy data can be approximated or the fitted RBF smoothed with low pass filtering during evaluation (meshing)
