Detailed Description

Archetype: 3D ellipsoids or spheres.

This archetype is for ellipsoids or spheres whose size is a key part of the data (e.g. a bounding sphere). For points whose radii are for the sake of visualization, use archetypes::Points3D instead.

If there's more instance poses than half sizes, the last ellipsoid/sphere's orientation will be repeated for the remaining poses. Orienting and placing ellipsoids/spheres forms a separate transform that is applied prior to archetypes::InstancePoses3D and archetypes::Transform3D.

Member Function Documentation

◆ with_half_sizes()

Ellipsoids3D rerun::archetypes::Ellipsoids3D::with_half_sizes ( const Collection< rerun::components::HalfSize3D > & _half_sizes ) &&

inline

For each ellipsoid, half of its size on its three axes.

If all components are equal, then it is a sphere with that radius.

◆ with_centers()

Ellipsoids3D rerun::archetypes::Ellipsoids3D::with_centers ( const Collection< rerun::components::PoseTranslation3D > & _centers ) &&

inline

Optional center positions of the ellipsoids.

If not specified, the centers will be at (0, 0, 0).

◆ with_rotation_axis_angles()

Ellipsoids3D rerun::archetypes::Ellipsoids3D::with_rotation_axis_angles ( const Collection< rerun::components::PoseRotationAxisAngle > & _rotation_axis_angles ) &&

inline

Rotations via axis + angle.

If no rotation is specified, the axes of the ellipsoid align with the axes of the local coordinate system.

◆ with_quaternions()

Ellipsoids3D rerun::archetypes::Ellipsoids3D::with_quaternions ( const Collection< rerun::components::PoseRotationQuat > & _quaternions ) &&

inline

Rotations via quaternion.

If no rotation is specified, the axes of the ellipsoid align with the axes of the local coordinate system.

◆ with_many_fill_mode()

Ellipsoids3D rerun::archetypes::Ellipsoids3D::with_many_fill_mode ( const Collection< rerun::components::FillMode > & _fill_mode ) &&

inline

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

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

◆ with_show_labels()

Ellipsoids3D rerun::archetypes::Ellipsoids3D::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()

Ellipsoids3D rerun::archetypes::Ellipsoids3D::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_class_ids()

Ellipsoids3D rerun::archetypes::Ellipsoids3D::with_class_ids ( const Collection< rerun::components::ClassId > & _class_ids ) &&

inline

Optional class ID for the ellipsoids.

The class ID provides colors and labels if not specified explicitly.

◆ columns() [1/2]

Collection< ComponentColumn > rerun::archetypes::Ellipsoids3D::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::Ellipsoids3D::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.
