🧮 Write your own source-controlled scripts for manipulating data​

We've added a new type of Foxglove extension that allows you to manipulate data and create new topics on the fly for visualization.

Semantically, these new topic message converters are similar to user scripts, but they are available across layouts and can be used to deploy "user-scripts" organization-wide. Like other extensions, they support code reuse, development in your own IDE, and use of third-party modules.

What used to be called a message converter is now called a schema message converter (schema converter for short). This new type of extension is called a topic message converter (topic converter).

How are the new Topic Message Converters different?​

Topic converters are more flexible than schema converters. Where schema converters assume a 1:1 relationship between proprietary schemas and well-known schemas, topic converters do not have this restriction. They can produce new topics from one or more input topics. These new topics can output custom types or other well-known schemas.

Topic converters support:

• One or more input topics
• Maintaining state (you can aggregate signal data from previous input messages to produce new output—allowing you to make filters or perform arbitrary math on signal data)
• Extract individual fields from a message to separate top-level topics
• View output of new topics in plots and State Transition panels (or any panels that use range subscriptions)

When should Schema Message Converters be used?​

We recommend using these when there is a 1:1 relationship between some internal schema and a well-known schema. Common examples:

• Converting proprietary GPS messages to foxglove.LocationFix for display in the Map panel
• Converting internal Log messages to foxglove.Log for the Log panel
• Converting business logic to foxglove.SceneUpdate for display in the 3D panel

📒 Multi-file upload​

You can now select multiple files and upload them simultaneously from the app.

⛰️ Support for Grid Maps in 3D​

We've added support for visualizing grid_map_msgs/GridMap messages in Foxglove. Grid Maps can be used to represent and visualize 2.5D height map information as well as other layers in the 3D panel. Common data layers stored in GridMap include elevation, variance, color, friction coefficient, foothold quality, surface normal, traversability, and more.

For visualizing surfaces in the 3D panel, Foxglove currently supports two interpolation methods between points:

• Nearest neighbour: Creates cube volumes at the nearest grid point containing the elevation data (faster, less accurate representation of the surface).
• Linear: The value of any point (x, y) on the surface is estimated using bilinear interpolation or the four neighboring grid points (slower, more accurate representation of the surface).

📐 Inspect and measure points in the Plot panel​

We've added inspect and measurement tools to the Plot panel. With the tool enabled, you can click on any point to highlight its x and y-values. Select a second point to view the x and y-delta between the points. Additionally, when viewing a path-based XY plot (as opposed to a time-series plot), the tool will also display the Euclidean distance between the two points.

🔬 Easier zooming in the Plot panel​

We've updated how you zoom in the Plot panel for a faster and more intuitive experience. When scrolling to zoom, hold Shift to zoom in y-axis and Alt/Option to zoom in the x-axis modifiers. You can also scroll either axis by hovering over the respective axis area for the plot.

📜 Quickly scroll through State Transitions​

If your State Transitions panel contains a large number of rows, you can now use Shift + Scroll to quickly scroll through them.

New & Improved

• Topics from scripts or converters are labeled as "from Script" or "from Converter" for topics generated by User Scripts or Converters respectively
• Non-critical URDF issues now appear as warnings instead of errors
• Added support for automatic min, max, and range detection for plots and state transitions using custom timestamp sources

Performance

• Added a "Compute vertex normals" toggle in the 3D panel to improve performance for large meshes
• Reduced initial opening time for ULog files
• Improved support for larger ULog files, enabling review of longer flight logs

Fixes

• Fixed an issue in the Plot panel where points were not displayed as expected
• Copying bigint values in the Raw Messages panel now copies them as numbers, not quoted strings
• Fixed a bug where certain paths would crash the Raw Messages panel
• Fixed an issue where the 3D panel transform tree frame list could get shuffled during looped playback
• Reduced flickering while streaming plot data
• Fixed a point cloud bug where some points would linger when in cube mode
• Fixed an issue where schemaless topics would not load from a streaming source
• Fixed an issue where holding down z rapidly toggled the zoom tool
• Fixed the "Retry" button after a network interruption
• Fixed an issue where Plot and State Transitions panels would get stuck at deep zoom levels
• Fixed an issue in the Image panel where large images could fail to synchronize with their annotations

Added

• inbox-listener: added MAX_FINALIZATION_WORKER_COUNT environment variable to configure the maximum worker count used to write files to the lake. This defaults to 40 and can be reduced to mitigate rate-limiting API errors from the lake bucket. When set to 0, the inbox listener uses one worker per topic in the input file.
