Detailed Description

Archetype: 3D arrows with optional colors, radii, labels, etc.

Example

Simple batch of 3D arrows

#include <rerun.hpp>
 
#include <cmath>
#include <vector>
 
constexpr float TAU = 6.28318530717958647692528676655900577f;
 
int main() {
    const auto rec = rerun::RecordingStream("rerun_example_arrow3d");
    rec.spawn().exit_on_failure();
 
    std::vector<rerun::Position3D> origins;
    std::vector<rerun::Vector3D> vectors;
    std::vector<rerun::Color> colors;
 
    for (int i = 0; i <100; ++i) {
        origins.push_back({0, 0, 0});
 
        float angle = TAU * static_cast<float>(i) * 0.01f;
        float length = log2f(static_cast<float>(i + 1));
        vectors.push_back({length * sinf(angle), 0.0, length * cosf(angle)});
 
        uint8_t c = static_cast<uint8_t>(round(angle / TAU * 255.0f));
        colors.push_back({static_cast<uint8_t>(255 - c), c, 128, 128});
    }
 
    rec.log(
        "arrows",
        rerun::Arrows3D::from_vectors(vectors).with_origins(origins).with_colors(colors)
    );
}

Member Function Documentation

with_origins()

Arrows3D rerun::archetypes::Arrows3D::with_origins ( Collection< rerun::components::Position3D >  _origins ) &&

inline

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

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

with_radii()

Arrows3D rerun::archetypes::Arrows3D::with_radii ( 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_class_ids()

Arrows3D rerun::archetypes::Arrows3D::with_class_ids ( Collection< rerun::components::ClassId >  _class_ids ) &&

inline

Optional class Ids for the points.

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

radii

std::optional<Collection<rerun::components::Radius> > rerun::archetypes::Arrows3D::radii

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.

class_ids

std::optional<Collection<rerun::components::ClassId> > rerun::archetypes::Arrows3D::class_ids

Optional class Ids for the points.

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