BoundingBox2D / BoundingBox3D

Axis-aligned bounding boxes for automatic viewport scaling.

Synopsis​

namespace Skigen::Plot {

struct BoundingBox2D {
    float xMin, xMax, yMin, yMax;

    auto width()  const -> float;
    auto height() const -> float;
    auto center() const -> Eigen::Vector2f;

    void expand(float x, float y);
    void merge(const BoundingBox2D& other);
};

struct BoundingBox3D {
    float xMin, xMax, yMin, yMax, zMin, zMax;

    auto width()  const -> float;
    auto height() const -> float;
    auto depth()  const -> float;
    auto center() const -> Eigen::Vector3f;

    void expand(float x, float y, float z);
    void merge(const BoundingBox3D& other);
};

} // namespace Skigen::Plot

Description​

Bounding boxes are computed automatically by PlotView when data is set via plot(), scatter(), or pointCloud(). They drive the auto-scaling of axes and the viewport transform.
