What does FastRBF™ do?
FastRBF smoothly interpolates scattered 2D and 3D data with Radial Basis Functions (RBFs).
No other technique can model irregular, non-uniformly sampled data as
effectively as RBF interpolation.
With FarField Technology's FastRBF™ software, millions of data measurements
can now be interpolated by a single function - a task previously thought
impossible on a desktop PC. The fitted function and its gradient can
be evaluated anywhere, such as on a grid, a plane or an arbitrary surface.
These capabilities make FastRBF ideal for visualizing scattered data,
particularly irregular, non-uniformly sampled data and reconstructing surfaces from range data.
Who should use FastRBF™?
- Engineers, software developers and scientists faced with large scattered data interpolation problems
- Researchers in computer graphics, reverse engineering and computer vision wanting to reconstruct surfaces from range data
- Students and researchers working with irregularly sampled 2D & 3D signals
- Those already working with RBFs who need to solve extremely large systems
The benefits of FastRBF™
FastRBF allows RBFs to be fitted to systems
with more than 1,000,000 data points on ordinary computing hardware. The polyharmonic (thin-plate) splines
that FastRBF uses result in the "smoothest" interpolant, in the sense
that they minimize the energy in the 2nd, 3rd, or
higher derivatives. This results in extraordinary extrapolation
capabilities when large gaps occur in a data set. In the case of
noisy data, FastRBF's error-bar fitter approximates the data with
the smoothest function within the error bounds specified at each data point.
Low-pass filtering of scattered data can also be achieved directly with FastRBF
without resampling on a regular grid and performing computationally intensive convolutions
in the spatial or Fourier domains.
Applications
FastRBF has already been applied a diverse range of engineering and research problems
from CAD-CAM rapid prototyping, Medical Imaging and Geophysics to Scientific visualisation, Computer graphics and Signal processing.
