----------------------------------------------------------------------------------------------------

GoTools is the name of a collection of C++ libraries related to geometry. The libraries are
organized as a core module with additional modules added on top. The core module contains generic
tools and spline functionality. The additional modules contain functionality for intersections,
approximative implicitization, parametrization, topology, and more.

This toolkit contains the modules gotools-core, gotools-data, igeslib, implicitization,
intersections, isogeometric_model, lrsplines2D, lrsplines3D, parametrization, qualitymodule,
topology, trivariate, trivariatemodel, viewlib and compositemodel. Also included is sisl ttl newmat
for convenience.

The GoTools geometry/spline toolkit was written by the Geometry Group at SINTEF ICT, Department of
Applied Mathematics.

Newmat was written by Robert Davies, http://www.robertnz.com.

Requirements:
* CMake - see: www.cmake.org
* Linux: Tested on the latest LTS version of Ubuntu (currently 20.04, using gcc version 9.3.0) on
  x64. It should work with gcc versions down to 4.8, but it is not actively supported. It has been
  tested to run on ARM64, but it is not actively supported.
* Windows: Tested with Visual Studio 2015, 2019 and 2022 on x64. Older versions are not
  supported. It has been tested to run on ARM64 (using x64 emulation), but it is not actively
  supported.
* MacOS: We do not officially support MacOS. It has beed tested to run on ARM64, but it is not
  actively supported.

Dependencies:
* PugiXML
* JsonCpp (required for viewlib only)
* Qt4/Qt5 (required for viewlib only)
* OpenGL (required for viewlib only)
* GLUT (required for viewlib only)
* Boost (required for running the test suite)

Optional dependencies (disabled by default):
* OpenMP

A few comments on the current distribution:
(1) You can generate doxygen information by typing 'doxygen' in the base directory.
(2) In order to compile/install the library, you need to use CMake. See the INSTALL file.
(3) GoTools provides a file format: g2. Various test applications produce g2 files as output. See
    the Doxygen generated documentation for more information on this format. The viewer application
    'goview' is provided in Viewlib in order to view g2-files.
