Detailed Description

Archetype: Configures how tensor scalars are mapped to color.

⚠ This type is unstable and may change significantly in a way that the data won't be backwards compatible.

Member Function Documentation

with_mag_filter()

TensorScalarMapping rerun::blueprint::archetypes::TensorScalarMapping::with_mag_filter ( const rerun::components::MagnificationFilter &  _mag_filter ) &&

inline

Filter used when zooming in on the tensor.

Note that the filter is applied to the scalar values before they are mapped to color.

with_gamma()

TensorScalarMapping rerun::blueprint::archetypes::TensorScalarMapping::with_gamma ( const rerun::components::GammaCorrection &  _gamma ) &&

inline

Gamma exponent applied to normalized values before mapping to color.

Raises the normalized values to the power of this value before mapping to color. Acts like an inverse brightness. Defaults to 1.0.

The final value for display is set as: colormap( ((value - data_display_range.min) / (data_display_range.max - data_display_range.min)) ** gamma )

columns() [1/2]

Collection< ComponentColumn > rerun::blueprint::archetypes::TensorScalarMapping::columns

(

const Collection< uint32_t > &

lengths_

)

Partitions the component data into multiple sub-batches.

Specifically, this transforms the existing ComponentBatch data into ComponentColumns instead, via ComponentBatch::partitioned.

This makes it possible to use RecordingStream::send_columns to send columnar data directly into Rerun.

The specified lengths must sum to the total length of the component batch.

columns() [2/2]

Collection< ComponentColumn > rerun::blueprint::archetypes::TensorScalarMapping::columns

(

)

Partitions the component data into unit-length sub-batches.

This is semantically similar to calling columns with std::vector<uint32_t>(n, 1), where n is automatically guessed.

Member Data Documentation

mag_filter

std::optional<ComponentBatch> rerun::blueprint::archetypes::TensorScalarMapping::mag_filter

Filter used when zooming in on the tensor.

Note that the filter is applied to the scalar values before they are mapped to color.

gamma

std::optional<ComponentBatch> rerun::blueprint::archetypes::TensorScalarMapping::gamma

Gamma exponent applied to normalized values before mapping to color.

Raises the normalized values to the power of this value before mapping to color. Acts like an inverse brightness. Defaults to 1.0.

The final value for display is set as: colormap( ((value - data_display_range.min) / (data_display_range.max - data_display_range.min)) ** gamma )

        )
