Extend the Viewer in Rust
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.
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
Above screenshot shows the
This example demonstrates how to add a fully custom Space View class to Rerun on startup.
Space Views that are added this way have access to the exact same interfaces as all other Space Views,
meaning that any of the built-in Space Views serves can serve as an additional example on how to implement Space Views.
⚠️ Note that the interface for adding Space Views are very far from stable. Expect code implementing custom Space Views to break with every release of Rerun.
We plan to also support embedding your own GUI widgets inside existing space views.
