What is the Presentation Tool?

The Presentation Tool project started as a project for Google Summer of Code 2020. The main idea is to have a software that is capable to create different sets of data configuration to be displayed on a Liquid Galaxy.

Liquid Galaxy is a very powerful tool to visualize data, the elevated computing power given by the main-secondary architecture and the larger visualization brings a very interesting field to show different types of media in bigger scales.

The API idea is to empower this capability of Liquid Galaxy by proposing the execution of different types of media at the same time using multiple processing with bash.

To deal with those creations, the API was developed to manage presentations. A presentation is a set of commands an user gives to the API, those commands are parsed and translated to open sets of media on specified positions, screens and time. To control the time of appearance and to be able to group sets of media, the presentation is divided into slides, so users can set how long they want a certain configuration on the Liquid Galaxy screens.

To help users manage the presentations, a tool was created to serve as a user interface connected directly with the API.

Because it consists of overlaying processes, the Presentation Tool can be used on top of Google Earth. Due to this powerful partnership, the Presentation Tool is integrated with the query system of Google Earth, making it possible to do queries while displaying the media.

Use cases
