🧮 Topic Converters can now output arrays of messages​

Topic Converters can now output an array of messages. This allows a topic converter to accept a single message as input and turn it into an array of messages on an output topic.

Example use case: Imagine you have lightweight sensor messages that are published at 1 kHz. Depending on system requirements, you may choose to aggregate and publish batches of messages at, say, 10 Hz on a /batch topic, which contains an array of messages: [WheelSpeedA, WheelSpeedB, WheelSpeedA, WheelSpeedA].

What if you want to write a converter that accepts /batch as input and outputs to a /wheel_a/speed topic, allowing you to plot your data as if each value was collected individually? This update allows your converter to accept one message from /batch and output N messages to /wheel_a/speed.

🐟 Fisheye camera support​

We've added support for fisheye camera images using the Kannala–Brandt image distortion model. The Kannala–Brandt model is popular for modeling fisheye distortion from wide-angle lenses and is used by several popular computer vision tools including OpenCV.

To use the Kannala–Brandt model, generate a CameraCalibration message and set the distortion_model parameter to kannala_brandt. Our implementation closely matches OpenCV's.

📈 Centered plot playback​

You can now adjust the playback bar position for a sliding time window in plots. Previously, the playback bar was always on the right edge—now you can center it for a more flexible view.

👀 View recordings in Timeline​

Use the Timeline to see a recording in context with other data for a particular device. You can now click the three-dot menu at the end of any recording in the recordings table and select "View in Timeline" to see it in the Timeline.

You can now toggle sections of the layout menu closed to focus on your workflow.

🧮 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.

• Added the ability to hide or show all transforms, while preserving individual frame visibility, in the 3D panel
• Tooltips for message path plots are now hidden for undefined series
• Proximity in both x and y dimensions is now used to select points for tooltips in plots
• Removed the vertical bar when hovering over non-time-series plots

⛰️ 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
