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.

Note that orienting and placing the ellipsoids/spheres is handled via [archetypes.InstancePoses3D]. Some of its component are repeated here for convenience. If there’s more instance poses than half sizes, the last half size will be repeated for the remaining poses.

Example

Covariance ellipsoid

use rand::distributions::Distribution;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let rec = rerun::RecordingStreamBuilder::new("rerun_example_ellipsoid_simple").spawn()?;

    let sigmas: [f32; 3] = [5., 3., 1.];

    let mut rng = rand::thread_rng();
    let normal = rand_distr::Normal::new(0.0, 1.0)?;

    rec.log(
        "points",
        &rerun::Points3D::new((0..50_000).map(|_| {
            (
                sigmas[0] * normal.sample(&mut rng),
                sigmas[1] * normal.sample(&mut rng),
                sigmas[2] * normal.sample(&mut rng),
            )
        }))
        .with_radii([0.02])
        .with_colors([rerun::Color::from_rgb(188, 77, 185)]),
    )?;

    rec.log(
        "ellipsoid",
        &rerun::Ellipsoids3D::from_centers_and_half_sizes(
            [(0.0, 0.0, 0.0), (0.0, 0.0, 0.0)],
            [sigmas, [sigmas[0] * 3., sigmas[1] * 3., sigmas[2] * 3.]],
        )
        .with_colors([
            rerun::Color::from_rgb(255, 255, 0),
            rerun::Color::from_rgb(64, 64, 0),
        ]),
    )?;

    Ok(())
}

Fields

half_sizes: Option<SerializedComponentBatch>

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

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

centers: Option<SerializedComponentBatch>

Optional center positions of the ellipsoids.

If not specified, the centers will be at (0, 0, 0). Note that this uses a components::PoseTranslation3D which is also used by archetypes::InstancePoses3D.

rotation_axis_angles: Option<SerializedComponentBatch>

Rotations via axis + angle.

If no rotation is specified, the axes of the ellipsoid align with the axes of the local coordinate system. Note that this uses a components::PoseRotationAxisAngle which is also used by archetypes::InstancePoses3D.

quaternions: Option<SerializedComponentBatch>

Rotations via quaternion.

If no rotation is specified, the axes of the ellipsoid align with the axes of the local coordinate system. Note that this uses a components::PoseRotationQuat which is also used by archetypes::InstancePoses3D.

colors: Option<SerializedComponentBatch>

Optional colors for the ellipsoids.

line_radii: Option<SerializedComponentBatch>

Optional radii for the lines used when the ellipsoid is rendered as a wireframe.

fill_mode: Option<SerializedComponentBatch>

Optionally choose whether the ellipsoids are drawn with lines or solid.

labels: Option<SerializedComponentBatch>

Optional text labels for the ellipsoids.

show_labels: Option<SerializedComponentBatch>

Optional choice of whether the text labels should be shown by default.

class_ids: Option<SerializedComponentBatch>

Optional class ID for the ellipsoids.

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

impl Ellipsoids3D

impl Ellipsoids3D

pub fn update_fields() -> Ellipsoids3D

Update only some specific fields of a Ellipsoids3D.

pub fn clear_fields() -> Ellipsoids3D

Clear all the fields of a Ellipsoids3D.

pub fn columns<I>( self, _lengths: I, ) -> Result<impl Iterator<Item = SerializedComponentColumn>, SerializationError>

where I: IntoIterator<Item = usize> + Clone,

Partitions the component data into multiple sub-batches.

Specifically, this transforms the existing SerializedComponentBatches data into SerializedComponentColumns instead, via SerializedComponentBatch::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.

pub fn columns_of_unit_batches( self, ) -> Result<impl Iterator<Item = SerializedComponentColumn>, SerializationError>

Helper to partition the component data into unit-length sub-batches.

This is semantically similar to calling Self::columns with std::iter::take(1).repeat(n), where n is automatically guessed.

pub fn with_half_sizes( self, half_sizes: impl IntoIterator<Item = impl Into<HalfSize3D>>, ) -> Ellipsoids3D

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

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

pub fn with_centers( self, centers: impl IntoIterator<Item = impl Into<PoseTranslation3D>>, ) -> Ellipsoids3D

Optional center positions of the ellipsoids.

If not specified, the centers will be at (0, 0, 0). Note that this uses a components::PoseTranslation3D which is also used by archetypes::InstancePoses3D.

pub fn with_rotation_axis_angles( self, rotation_axis_angles: impl IntoIterator<Item = impl Into<PoseRotationAxisAngle>>, ) -> Ellipsoids3D

Rotations via axis + angle.

If no rotation is specified, the axes of the ellipsoid align with the axes of the local coordinate system. Note that this uses a components::PoseRotationAxisAngle which is also used by archetypes::InstancePoses3D.

pub fn with_quaternions( self, quaternions: impl IntoIterator<Item = impl Into<PoseRotationQuat>>, ) -> Ellipsoids3D

Rotations via quaternion.

If no rotation is specified, the axes of the ellipsoid align with the axes of the local coordinate system. Note that this uses a components::PoseRotationQuat which is also used by archetypes::InstancePoses3D.

pub fn with_colors( self, colors: impl IntoIterator<Item = impl Into<Color>>, ) -> Ellipsoids3D

Optional colors for the ellipsoids.

pub fn with_line_radii( self, line_radii: impl IntoIterator<Item = impl Into<Radius>>, ) -> Ellipsoids3D

Optional radii for the lines used when the ellipsoid is rendered as a wireframe.

Optionally choose whether the ellipsoids are drawn with lines or solid.

pub fn with_many_fill_mode( self, fill_mode: impl IntoIterator<Item = impl Into<FillMode>>, ) -> Ellipsoids3D

This method makes it possible to pack multiple crate::components::FillMode in a single component batch.

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

pub fn with_labels( self, labels: impl IntoIterator<Item = impl Into<Text>>, ) -> Ellipsoids3D

Optional text labels for the ellipsoids.

pub fn with_show_labels( self, show_labels: impl Into<ShowLabels>, ) -> Ellipsoids3D

pub fn with_many_show_labels( self, show_labels: impl IntoIterator<Item = impl Into<ShowLabels>>, ) -> Ellipsoids3D

This method makes it possible to pack multiple crate::components::ShowLabels in a single component batch.

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

pub fn with_class_ids( self, class_ids: impl IntoIterator<Item = impl Into<ClassId>>, ) -> Ellipsoids3D

Optional class ID for the ellipsoids.

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

impl Ellipsoids3D

pub fn from_radii(radii: impl IntoIterator<Item = f32>) -> Ellipsoids3D
