Logging functions
rerun
def log(entity_path, entity, *extra, timeless=False, recording=None, strict=None)
Log data to Rerun.
This is the main entry point for logging data to rerun. It can be used to log anything
that implements the rerun.AsComponents
interface, or a collection of ComponentBatchLike
objects.
When logging data, you must always provide an entity_path for identifying the data. Note that the path prefix "rerun/" is considered reserved for use by the Rerun SDK itself and should not be used for logging user data. This is where Rerun will log additional information such as warnings.
The most common way to log is with one of the rerun archetypes, all of which implement
the AsComponents
interface.
For example, to log a 3D point:
rr.log("my/point", rr.Points3D(position=[1.0, 2.0, 3.0]))
The log
function can flexibly accept an arbitrary number of additional objects which will
be merged into the first entity so long as they don't expose conflicting components, for instance:
# Log three points with arrows sticking out of them,
# and a custom "confidence" component.
rr.log(
"my/points",
rr.Points3D([[0.2, 0.5, 0.3], [0.9, 1.2, 0.1], [1.0, 4.2, 0.3]], radii=[0.1, 0.2, 0.3]),
rr.Arrows3D(vectors=[[0.3, 2.1, 0.2], [0.9, -1.1, 2.3], [-0.4, 0.5, 2.9]]),
rr.AnyValues(confidence=[0.3, 0.4, 0.9]),
)
