class AggregationPolicy
Bases: Enum
Component: Policy for aggregation of multiple scalar plot values.
This is used for lines in plots when the X axis distance of individual points goes below a single pixel, i.e. a single pixel covers more than one tick worth of data. It can greatly improve performance (and readability) in such situations as it prevents overdraw.

class PoseTransformMat3x3
Bases: Mat3x3, ComponentMixin
Component: A 3x3 transformation matrix Matrix that doesn't propagate in the transform hierarchy.
3x3 matrixes are able to represent any affine transformation in 3D space, i.e. rotation, scaling, shearing, reflection etc.
Matrices in Rerun are stored as flat list of coefficients in column-major order:
column 0 column 1 column 2
-------------------------------------------------
row 0 | flat_columns[0] flat_columns[3] flat_columns[6]
row 1 | flat_columns[1] flat_columns[4] flat_columns[7]
row 2 | flat_columns[2] flat_columns[5] flat_columns[8]
However, construction is done from a list of rows, which follows NumPy's convention:
np.testing.assert_array_equal(
rr.components.PoseTransformMat3x3([1, 2, 3, 4, 5, 6, 7, 8, 9]).flat_columns, np.array([1, 4, 7, 2, 5, 8, 3, 6, 9], dtype=np.float32)

class Radius
Bases: RadiusExt, Float32, ComponentMixin
Component: The radius of something, e.g. a point.
Internally, positive values indicate scene units, whereas negative values are interpreted as UI points.
UI points are independent of zooming in Views, but are sensitive to the application UI scaling. at 100% UI scaling, UI points are equal to pixels The Viewer's UI scaling defaults to the OS scaling which typically is 100% for full HD screens and 200% for 4k screens.

Bases: TensorData, ComponentMixin
Component: An N-dimensional array of numbers.
The number of dimensions and their respective lengths is specified by the shape field.
The dimensions are ordered from outermost to innermost. For example, in the common case of
a 2D RGB Image, the shape would be [height, width, channel].
These dimensions are combined with an index to look up values from the buffer field,
which stores a contiguous array of typed values.

The TensorData object is internally represented by three fields: shape and buffer.
This constructor provides additional arguments 'array', and 'dim_names'. When passing in a

populated automagically.
