Detailed Description

Archetype: 2D arrows with optional colors, radii, labels, etc.

Example

Simple batch of 2D arrows

#include <rerun.hpp>
 
int main() {
    const auto rec = rerun::RecordingStream("rerun_example_arrow2d");
    rec.spawn().exit_on_failure();
 
    rec.log(
        "arrows",
        rerun::Arrows2D::from_vectors({{1.0f, 0.0f}, {0.0f, -1.0f}, {-0.7f, 0.7f}})
            .with_radii(0.025f)
            .with_origins({{0.25f, 0.0f}, {0.25f, 0.0f}, {-0.1f, -0.1f}})

Member Function Documentation

◆ with_origins()

Arrows2D rerun::archetypes::Arrows2D::with_origins ( const Collection< rerun::components::Position2D > & _origins ) &&

inline

All the origin (base) positions for each arrow in the batch.

If no origins are set, (0, 0) is used as the origin for each arrow.

◆ with_radii()

Arrows2D rerun::archetypes::Arrows2D::with_radii ( const Collection< rerun::components::Radius > & _radii ) &&

inline

Optional radii for the arrows.

The shaft is rendered as a line with radius = 0.5 * radius. The tip is rendered with height = 2.0 * radius and radius = 1.0 * radius.

◆ with_labels()

Arrows2D rerun::archetypes::Arrows2D::with_labels ( const Collection< rerun::components::Text > & _labels ) &&

inline

Optional text labels for the arrows.

If there's a single label present, it will be placed at the center of the entity. Otherwise, each instance will have its own label.

◆ with_show_labels()

Arrows2D rerun::archetypes::Arrows2D::with_show_labels ( const rerun::components::ShowLabels & _show_labels ) &&

inline

Whether the text labels should be shown.

If not set, labels will automatically appear when there is exactly one label for this entity or the number of instances on this entity is under a certain threshold.

◆ with_many_show_labels()

Arrows2D rerun::archetypes::Arrows2D::with_many_show_labels ( const Collection< rerun::components::ShowLabels > & _show_labels ) &&

inline

This method makes it possible to pack multiple show_labels in a single component batch.

This only makes sense when used in conjunction with columns. with_show_labels should be used when logging a single row's worth of data.

◆ with_draw_order()

Arrows2D rerun::archetypes::Arrows2D::with_draw_order ( const rerun::components::DrawOrder & _draw_order ) &&

inline

An optional floating point value that specifies the 2D drawing order.

Objects with higher values are drawn on top of those with lower values.

◆ with_many_draw_order()

Arrows2D rerun::archetypes::Arrows2D::with_many_draw_order ( const Collection< rerun::components::DrawOrder > & _draw_order ) &&

inline

This method makes it possible to pack multiple draw_order in a single component batch.

This only makes sense when used in conjunction with columns. with_draw_order should be used when logging a single row's worth of data.

◆ with_class_ids()

Arrows2D rerun::archetypes::Arrows2D::with_class_ids ( const Collection< rerun::components::ClassId > & _class_ids ) &&

inline

Optional class Ids for the points.

The components::ClassId provides colors and labels if not specified explicitly.

◆ columns() [1/2]

Collection< ComponentColumn > rerun::archetypes::Arrows2D::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::archetypes::Arrows2D::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.
