.. _a_ecosystem: User interfaces ^^^^^^^^^^^^^^^ You can work with 3Di both in the browser and locally. We offer three user interfaces, each with their own specific strengths. * :ref:`3Di Live <3di_live_introduction>`: run interactive simulations in the browser and follow them while they are running. * :ref:`The 3Di Modeller Interface `: a desktop application for modelling experts and hydrologists, based on QGIS. Here you can build and edit schematisations, start simulations, and analyze results. * :ref:`3Di Management `: manage online 3Di resources such as schematisations, models, simulation templates and simulations. These three interfaces all interact with the 3Di server through the same :ref:`a_api`, a comprehensive *application programming interface*. You can use this API to interact with 3Di from a Python script or your own software product. All components are secured by an **Authentication** and **Authorization** system, see :ref:`f_authentication_user_management`. .. figure:: image/a_3di_ecosystem.png :alt: Interaction with 3Di through its API Interaction with 3Di through its API.
