Camera3D

View and projection matrix management for 3D visualizations.

Synopsis​

namespace Skigen::Plot {

class Camera3D {
public:
    Camera3D();

    void lookAt(const Eigen::Vector3f& eye,
                const Eigen::Vector3f& target,
                const Eigen::Vector3f& up = Eigen::Vector3f::UnitY());

    void setPerspective(float fovDegrees, float aspect,
                        float nearPlane, float farPlane);

    auto viewMatrix()           const -> Eigen::Matrix4f;
    auto projectionMatrix()     const -> Eigen::Matrix4f;
    auto viewProjectionMatrix() const -> Eigen::Matrix4f;

    auto position() const -> const Eigen::Vector3f&;
    auto target()   const -> const Eigen::Vector3f&;
};

} // namespace Skigen::Plot

Description​

Camera3D computes standard right-handed view and perspective projection matrices. Used by PlotView for 3D rendering modes (point clouds, surface meshes).

See the Camera3D guide for detailed usage and the mathematical derivation.
