# Pixyz UI Overview

> This page provides an overview of the Pixyz UI, covering model import, navigation controls, selection modes, and ways to execute SDK functions.

The Pixyz UI is a simple interface where you can test Pixyz SDK functionality on your models and familiarize yourself with Pixyz concepts. When you open it for the first time, you will see our DefaultUI, the following is a short overview of its functionality. If you want to modify it or create your own, see [Create a Custom UI](./custom).

## Importing a model

To import any file, just drag and drop it on the Pixyz UI. A list of supported file formats can be found [here](./../io/supported-formats). Alternatively, you can select a file via `IO/Import File` in the menu bar or by pressing **Ctrl+I**.

## Navigation

| Camera Rotation  | Set Rotation Center | Camera Panning   | Camera Zoom                      | Selection | Depth Selection |
| ---------------- | ------------------- | ---------------- | -------------------------------- | --------- | --------------- |
| ALT + LMB (drag) | MMB click           | ALT + MMB (drag) | ALT + RMB (drag) or scroll wheel | LMB       | RMB             |

## Selection

| New Selection | Invert Selection | Add To Selection   | Remove From Selection |
| ------------- | ---------------- | ------------------ | --------------------- |
| LMB           | CTRL + LMB       | CTRL + SHIFT + LMB | SHIFT + LMB           |

### Selection modes

It is possible to select either Connected Meshes, Edges, Parts (default), Patches or Polygons. However, note that almost all algorithms can only work with occurrences that are selected using the `Part` mode.

## Executing Pixyz SDK functions

### Function Browser

Any function available in the SDK can be tested by opening the Function Browser window at `Windows/Function Browser`. After entering your parameters, it is also possible to copy the function code as a python snippet to clipboard.

### Command Palette

There is also a simple Command Palette available, which can be opened with **Ctrl+Shift+P**. You can search for functions and press **Enter** to open a popup which enables you to execute that function. This is not different from the Function Browser, but more convenient for working quickly.

### Scripting

Additionally, there is a scripting window which can be opened via `Windows/Scripting` . Due to its limited functionality, it is **not recommended** to write long scripts inside the Pixyz UI. It has proven most efficient for small iterations, to import and test existing scripts or just to tweak parameters. Anything else should be done using your preferred IDE with the Pixyz SDK.

## Modifying Preferences

[Pixyz SDK properties](./../preferences) can be modified via `Windows/Properties`. For Viewer properties, `Windows/Visualization` can be used to access preferences that are viewer-specific. Keep in mind that these settings will be saved in between sessions.

## Additional Functionality

Pixyz UI comes with multiple predefined windows, which can be accessed via the `Windows` dropdown in the menu bar. They range from a simple animation player to a more elaborated UV Viewer tool and many others.
