# Introduction to Glass

Glass is a new dashboard and robot data visualization tool. It supports many of the same widgets that the Simulation GUI supports, including robot pose visualization and advanced plotting. In its current state, it is meant to be used as a programmer’s tool for debugging and not as a dashboard for competition use.

## Opening Glass

Glass can be launched by selecting the ellipsis menu (…) in VS Code, clicking on Start Tool and then choosing Glass.

Note

You can also launch Glass directly by navigating to `~/wpilib/YYYY/tools` and running `Glass.py` (Linux and macOS) or by using the shortcut inside the WPILib Tools desktop folder (Windows).

## Changing View Settings

The View menu item contains Zoom and Style settings that can be customized. The Zoom option dictates the size of the text in the application whereas the Style option allows you to select between the `Classic`, `Light`, and `Dark` modes.

An example of the `Dark` style setting is below:

## Clearing Application Data

Application data for Glass, including widget sizes and positions as well as other custom information for widgets is stored in a `glass.ini` file. The location of this file varies based on your operating system:

- On Windows, the configuration file is located in `%APPDATA%`.

- On macOS, the configuration file is located in `~/Library/Preferences`.

- On Linux, the configuration file is located in `$XDG_CONFIG_HOME` or `~/.config` if the former does not exist.

The `glass.ini` configuration file can simply be deleted to restore Glass to a “clean slate”.
