Rerun

Components

Components are the fundamental unit of logging in Rerun. This page lists all built-in components.

An entity can only ever contain a single array of any given component type. If you log the same component several times on an entity, the last value (or array of values) will overwrite the previous.

For more information on the relationship between archetypes and components, check out the concept page on Entities and Components.

  • AggregationPolicy: Policy for aggregation of multiple scalar plot values.
  • AnnotationContext: The AnnotationContext provides additional information on how to display entities.
  • AxisLength: The length of an axis in local units of the space.
  • Blob: A binary blob of data.
  • ClassId: A 16-bit ID representing a type of semantic class.
  • ClearIsRecursive: Configures how a clear operation should behave - recursive or not.
  • Color: An RGBA color with unmultiplied/separate alpha, in sRGB gamma space with linear alpha.

  • DepthMeter: The world->depth map scaling factor.
  • DisconnectedSpace: Spatially disconnect this entity from its parent.
  • DrawOrder: Draw order of 2D elements. Higher values are drawn on top of lower values.
  • FillRatio: How much a primitive fills out the available space.
  • GammaCorrection: A gamma correction value to be used with a scalar value or color.
  • HalfSize2D: Half-size (radius) of a 2D box.
  • HalfSize3D: Half-size (radius) of a 3D box.
  • ImagePlaneDistance: The distance from the camera origin to the image plane when the projection is shown in a 3D viewer.
  • KeypointId: A 16-bit ID representing a type of semantic keypoint within a class.
  • LineStrip2D: A line strip in 2D space.
  • LineStrip3D: A line strip in 3D space.
  • MagnificationFilter: Filter used when magnifying an image/texture such that a single pixel/texel is displayed as multiple pixels on screen.
  • MarkerShape: The visual appearance of a point in e.g. a 2D plot.
  • MarkerSize: Radius of a marker of a point in e.g. a 2D plot, measured in UI points.
  • Material: Material properties of a mesh, e.g. its color multiplier.
  • MediaType: A standardized media type (RFC2046, formerly known as MIME types), encoded as a utf8 string.
  • Name: A display name, typically for an entity or a item like a plot series.
  • Opacity: Degree of transparency ranging from 0.0 (fully transparent) to 1.0 (fully opaque).
  • OutOfTreeTransform3D: An out-of-tree affine transform between two 3D spaces, represented in a given direction.
  • PinholeProjection: Camera projection, from image coordinates to view coordinates.
  • Position2D: A position in 2D space.
  • Position3D: A position in 3D space.
