Component mappings
meshtopoint.mp4
You can now map components more generally. Want to display your mesh as a point cloud? Just add a point cloud visualizer and select the vertex positions as the source.
Prettier primitives

0.30.0 - Plot any scalar & on-demand streaming
Rerun is an easy-to-use database and visualization toolbox for multimodal and temporal data.
Try it live at https://rerun.io/viewer.
- Python:
pip install rerun-sdk - Rust:
cargo add rerunandcargo install rerun-cli --locked - Online demo: https://rerun.io/viewer
- C++ FetchContent: https://github.com/rerun-io/rerun/releases/download/0.30.0/rerun_cpp_sdk.zip
🧳 Migration guide: https://rerun.io/docs/reference/migration/migration-0-30
✨ Overview & highlights
📈 Plot any scalar
anyscalar.action.4.mp4
You can now plot any scalar value, even if it lacks Rerun semantics in time series views. For instance, this lets you plot any value in an MCAP file.
In addition to plotting scalars from MCAP files, it is now possible to visualize arbitrary scalar components that were logged using AnyValues or DynamicArchetype. The supported data types are:
Float32andFloat64Int8,Int16,Int32, andInt64UInt8,UInt16,UInt32, andUInt64Boolean- Any of the above nested inside of Arrow structs.
This also makes it possible to log and visualize multiple scalars to the same entity, which can drastically reduce the size of the resulting .rrd files.
Note that by default, and without blueprints, views are still only spawned for entities with Rerun semantics.
Time series views for entities with custom scalar components need to be spawned either:
- from the context menu of the streams,
- by adding a view from the blueprint panel,
- or by specifying a blueprint using the Python or Rust SDK.
The components that should be visualized can be selected via a new dropdown menu from the completely revised visualizer section in the selection panel.
To quickly navigate to the desired visualizer, each time series view now shows an overview of it's current visualizers.
For more details please refer to our documentation:
- Customize views
- Plot any scalar
- Component mappings outside of plotting, shown on the example of a colored point cloud
Thanks to a contribution from @vfilter, the series lines visualizer now also supports different interpolation modes to render staircase (or step) functions:
📡 On-demand streaming / larger-than-RAM
The Rerun Viewer now supports on-demand streaming, when connected to either the OSS server or Rerun Cloud.
on-demand-streaming.mp4
With on-demand streaming, whatever you are currently viewing will be downloaded first.
This includes time-scrubbing to the end of a very long recording and quickly seeing what is there, or viewing only one camera feed of many.
Of course, your memory limit will be respected, and when you change your view or move the time cursor, the stale data will be evicted and the new data downloaded.
This also means that the web viewer can finally view recordings larger than the 4GiB limit enforced by Wasm32, as long as those recordings are served by a Rerun server.
It also means that Rerun Cloud users can view huge recordings, larger than what fits into RAM.
The OSS server, however, still loads everything into RAM before serving it.
Usage:
> rerun server -d folder_with_large_recordings
Then either open the native viewer:
> rerun "rerun+http://127.0.0.1:51234"
Or the web viewer:
> rerun --serve-web "rerun+http://127.0.0.1:51234"
🦾 Support for many more MCAP message types
Like in the previous releases, we're continually expanding our support for common robotics data to make it easier for users to load their existing recordings.
This release adds support for Foxglove Protobuf schemas to our built-in MCAP data loader, in addition to the existing set of supported ROS 2 messages.
You can find an overview of all the messages that are currently supported here.
🎨 Extend existing views without forking
Previously, extending the Viewer with custom Rust code required creating an entirely new view type,
even if you just wanted to add a single new visualization to the existing 3D view.
Now, you can register custom visualizers that plug directly into existing views, using fully custom archetypes & shaders in the process!
2026-02-20_17-13-08.mp4
In practice this works currently only well for 2D, 3D, and Map views but we'll keep working towards
making the Viewer more and more modular & extensible!
For more details, see the custom visualizer example and the viewer rust extension docs for a general overview.
