0.8.0 - Infrastructure investments and more transform improvements - 2023-07-27

Rerun is an easy-to-use visualization toolbox for computer vision and robotics.

• Python: pip install rerun-sdk
• Rust: cargo add rerun and cargo install rerun-cli
• Online demo: https://demo.rerun.io/version/0.8.0/

Overview & Highlights

• log_pinhole is now easier to use in simple cases and supports non-RDF camera coordinates. #2614
  • You only need to set focal length and optional principal point instead of setting the full 3x3 matrix.
  • There is also a new argument: camera_xyz for setting the coordinate system. The default is RDF (the old
    default). This affects the visible camera frustum, how rays are projected when hovering a 2D image, and how depth
    clouds are projected.
• The visualizer can now show coordinate arrows for all affine transforms within the view. #2577
• Linestrips and oriented bounding boxes can now be logged via batch APIs in python.
  • See: log_linestrips_2d, log_linestrips_3d, #2822 and log_obbs #2823
• Rust users that build their own Viewer applications can now add fully custom Space Views. Find more information here.
• New optional flush_timeout specifies how long Rerun will wait if a TCP stream is disconnected during a flush. #2821
  • In Rust, RecordingStream::connect now requires flush_timeout specified as an Option<Duration>.
    • To keep default behavior, this can be specified using the rerun::default_flush_time() helper.
  • In Python flush_init_sec is now an optional argument to rr.connect()
• In Rust, the RecordingStream now offers a stateful time API, similar to the Python APIs. #2506
  • You can now call set_time_sequence, set_time_seconds, and set_time_nanos directly on the RecordingStream,
    which will set the time for all subsequent logs using that stream.
  • This can be used as an alternative to the the previous MsgSender::with_time APIs.
• The Rerun SDK now defaults to 8ms long microbatches instead of 50ms. This makes the default behavior more suitable for use-cases like real-time video feeds. #2220
  • Check out the microbatching docs for more information
    on fine-tuning the micro-batching behavior.
• The web viewer now incremental loads .rrd files when streaming over HTTP. #2412

Ongoing Refactors

• There have been a number of significant internal changes going on during this release with little visible impact.
  This work will land across future releases, but is highlighted here since much of it is visible through the
  changelog.
  • The layout of the Viewer is now controlled by a Blueprint datastore. In the future this will allow for direct API
    control of the layout and configuration of the Viewer. A very early prototype of this functionality is available
    via the rerun.experimental module in Python.
  • An entirely new code-generation framework has been brought online for Rust, Python and C++. This will eventually enable
    new object-centric APIs with a more scalable, consistent, and ergonomic experience.
  • Bringup of C++ support is now underway and will eventually become our third officially supported SDK language.

Known Regressions

• Due to the Blueprint storage migration, blueprint persistence on web is currently broken. Will be resolved in:
  #2579
