Helios Documentation v1.3.10




The Helios simulation system is a versatile modeling framework that handles tasks such as managing geometry and associated data structures through a C++ API. Plug-ins build on the Helios core engine, and access the geometry and data via the Helios context. The system comes with a visualization plug-in that can produce stunning renderings of model geometry and data with relatively little effort.


System Requirements

Helios is compatible with Mac, Linux, and PC platforms. Some plug-ins require an NVIDIA graphics processing unit (GPU), such as the radiation model and LiDAR plug-ins.


Downloading the Code

The code repository is located at https://www.github.com/PlantSimulationLab/Helios. The best way to download it is using "git", which allows you to easily update your code when new updates are available.

To do so, first install git, then using your command-line interface (e.g. terminal) change into the directory where you want to download the code, then type:

$ git clone %https://www.github.com/PlantSimulationLab/Helios

As updates are released, update your version of the code by typing:

$ git pull

You can always check which version you are on by typing:

$ git log
