Binary Download

The standard way of using pre-packaged binaries is to download them from TiGL's release page https://github.com/DLR-SC/tigl/releases. Here, we offer packages for Windows and macOS (Darwin).

Linux

There are two ways to install TiGL on Linux:

Use the package manager of your distribution. Just go to https://software.opensuse.org/download.html?project=science:dlr&package=tigl3, choose your linux distribution and follow the instructions.
If you can't install system wide packages, we provide a helper script https://github.com/DLR-SC/tigl/blob/master/misc/get_tigl_tixi.sh that downloads and decompresses the required packages.

Python

The easiest way to install TiGL and all its dependencies for Python is using Conda. Conda is a package manager for Python packages and allows the distribution of pre-compiled packages.

To install TiGL into a separate environement, enter the following from the conda command prompt

conda create -n tigl_env tigl3 -c dlr-sc

All TiGL related packages are now found inside the tigl_env environment. To enter this environment, type

conda activate tigl_env

Have a look to our examples at https://github.com/DLR-SC/tigl-examples on how to use the Python bindings.

Matlab

The TiGL binary distribution includes interfaces to the MATLAB language. On Windows systems, we ship with a precompiled MEX file and script files that can be found under share/tigl3/matlab.

On Linux, we cannot provide precompiled binaries of the interface. Instead you can find all script files and the MEX input file tiglmatlab.c under share/tigl3/matlab. To compile the MATLAB bindings, the tool "mex" is required, which is typically part of each MATLAB installation. To compile, use our Makefile by typing in the command "make".

Our small Matlab demo at https://github.com/DLR-SC/tigl/tree/master/examples/matlab_demo demonstrates, how to use TiGL's Matlab bindings.

Building from source

The minimum requirements to build TiGL are TiXI and OpenCascade Technology (OCCT). Qt5 is needed if you want to build the tiglviewer. All build dependencies of TiGL are available as conda packages. Most dependencies are supplied in a decicated channel at https://anaconda.org/dlr-sc/. Specifically, this channel contains a recommended variant of opencascade, which includes a patch for G2-continuous Coons patches. The recipes for the conda packages in the dlr-sc channel can be found at https://github.com/DLR-SC/tigl-conda.

We recommend installing TiGL's dependencies via conda in a seperate environment. You can find our recommended environment file for the latest development version at https://github.com/DLR-SC/tigl/tree/master/environment.yml. To create this environment locally, enter the following command from the conda command prompt:

conda create -f environment.yml

This command will install a new environment called tigl-bld with all dependencies pre-installed. Next activate the environment:

conda activate tigl-bld

Now tigl can be configured and build using cmake:

mkdir build
cd build
cmake ..
cmake --build .

This will configure TiGL with default options. An example of a customized cmake configuration could look like this:

cmake .. -GNinja \
         -DCMAKE_BUILD_TYPE=Release \
         -DCMAKE_INSTALL_PREFIX=install \
         -DOCE_STATIC_LIBS=ON \
         -DTIGL_BUILD_TESTS=ON \
         -DTIGL_ENABLE_COVERAGE=ON \
         -DTIGL_CONCAT_GENERATED_FILES=ON \
         -DTIGL_BINDINGS_PYTHON_INTERNAL=ON \
         -DTIGL_BINDINGS_MATLAB=ON \
         -DTIGL_BINDINGS_JAVA=ON \
         -DTIGL_NIGHTLY=ON
