## Qt 3D vs. Qt 3D Studio

See the Comparison of Qt 3D and Qt 3D Studio section for a full comparison of Qt 3D and Qt 3D Studio.

## Concepts

### Project

A project is simply a folder on your computer holding all the assets needed for your application. When you start a new project, a default folder structure will be created.

### Application

Your application is the entry point of your project. It is represented by a single `.uia` file at the root of your project folder. This file references the presentation and sub-presentations in your project. The application is what is displayed by the Viewer.

### Presentation

Artists use Studio to create presentation files, represented by `.uip` files in your project. A presentation has one or more layers composited to the screen, comprised of 2D and 3D assets created in other applications.

Each application can only have one main presentation shown on screen (specified by the `.uia` file) but this presentation may reference other sub-presentations, either on flat layers or as images and textures drawn in a scene.

### QML

Additional functionality can be built on top of the Qt 3D Studio presentations with QML by incorporating applications or presentations into QML with the Studio3D element.

### Layer

A single Studio presentation combines one or more layers. The visual result of each layer comes from rendering a 3D scene, 2D scene (via an orthographic camera), or sub-presentation. Layers are then composited with items on upper layers drawing on top of the content on lower layers.

### Slide

A Studio presentation combines 3D assets with animations and slides. Slides can be thought of as states and provide visual variations within the presentation.
