Icon Siscat (The SINTEF Scattered Data Library) consists of a collection of object-oriented libraries (implemented in C++) for the construction of surfaces from scattered data. Typical applications are geophysical modelling, terrain modelling and surface modelling for CAD applications.

The libraries, which are implemented in C++, are organized into several layers:

  • BasicTools: Non-numerical utilities such as memory handling, basic array structures, menu system and generic I/O.
  • LaTools: Class hierarchies for representation of different vector and matrix formats and linear algebra tools, such as direct and iterative solvers.
  • ssKernel: Data structures and data interfaces, a range of methods for constructing explicit surfaces of two variables.
  • ssAppl: Generic applications for different problem areas such as large seamless terrain models and and free form surfaces.
The BasicTools and LaTools libraries are developed under the Diffpack project.

Current Version:   2.2

License Type:   Siscat is commercial software, please contact Numerical Objects AS for details. However, a public domain stripped version is planned to be made available on the internet within the end of 1997. This will be available as source code for non-commercial, academic use.
