# Build Your First App

The Examples/BuildYourFirstApp folder contains 4 simple examples showcasing how to get started with the 3 main components of Envision. This is a good place to start to see how to use HOOPS Envision. The examples are:

1. Hello Envision : Minimal Envision app using the geometry model `GeometryModel` to draw two simple objects.
2. Viewer: A simple demonstration on how to use the `ConstantRemoteModel` to show pre-defined models in a scalable way.
3. FirstPostProcessor: A very simple interactive CAE post-processor showcasing the `RemoteModel`.
4. FeatureExtraction: The second example featuring the `RemoteModel`. This time with a focus on cutting planes, isovolumes and particle traces.

To setup your own server and dig more info the `RemoteModel`, see the Server for Remote Models (UgServer) chapter.
