Extend the Viewer UI in Rust

What you can build

In the above screenshot you see the example extend_viewer_ui, which contains the Rerun Viewer to the left and a custom panel to the right. In this example the panel contains a hierarchial text view of the loaded data.

How to build it

The Rerun Viewer is defined by the crate re_viewer. It uses the popular Rust GUI library egui (written by our CTO) and its framework eframe. To extend the UI you need to create your own eframe application and embed re_viewer inside of it. You can then use egui to add custom panels and windows.

The best way to get started is by reading the source code of the extend_viewer_ui example.

Future work

We plan to also support embedding your own GUI widgets and views inside the viewer.
