Welcome to the SISL wiki!

SISL is a comprehensive NURBS library for the modeling and interrogation of curves and surfaces. It is implemented in C.

The software was written by the Geometry Group at SINTEF Digital, Department of Mathematics and Cybernethics.

This package uses CMake to generate a Makefile (on Linux) or MS Visual Studio project file (on Windows).

For information on using CMake, see www.cmake.org.

A more extensive guide on how to compile and link the SISL library and applications build upon it can be found in the reference manual. The manual also contains a description of all top level functions in the library as well as a set of sample programs and a simple viewer.

LINUX

As a Quick Start Guide, on Linux, make a build directory inside the source directory $ cd <path_to_source_code> $ mkdir build $ cd build

Run the cmake program to setup the build process, selecting Debug or Release as build type, optionally selecting a local install folder: $ cmake .. -DCMAKE_BUILD_TYPE=Release (-DCMAKE_INSTALL_PREFIX=$HOME/install)

For a gui-like cmake interface use ccmake (from cmake-ncurses-gui).

Build the library: $ make

Install the library to a local folder (requires the use of -DCMAKE_INSTALL_PREFIX with a local folder in the previous step): $ make install

If the -DCMAKE_INSTALL_PREFIX in the cmake step was omitted or was set to a system folder (like /usr/local) the user needs elevated privileges to install the library: $ sudo make install

WINDOWS

On Windows, add a new build folder somewhere. Start the CMake executable and fill in the paths to the source and build folders. When you run CMake, a Visual Studio project solution file will be generated in the build folder.
