## Detailed Description

This 3D Widget represents a trajectory. :

## Constructor & Destructor Documentation

## ◆ WTrajectoryFrustums() [1/2]

cv::viz::WTrajectoryFrustums::WTrajectoryFrustums | ( | InputArray | path,
|  | const Matx33d & | K,
|  | double | scale = `1.`,
|  | const Color & | color = `Color::white()`
| ) |  |

Constructs a WTrajectoryFrustums.

Parameters

  path | List of poses on a trajectory. Takes std::vector<Affine<T>> with T == [float | double]
  K | Intrinsic matrix of the camera.
  scale | Scale of the frustums.
  color | Color of the frustums.

Displays frustums at each pose of the trajectory.

## ◆ WTrajectoryFrustums() [2/2]

cv::viz::WTrajectoryFrustums::WTrajectoryFrustums | ( | InputArray | path,
|  | const Vec2d & | fov,
|  | double | scale = `1.`,
|  | const Color & | color = `Color::white()`
| ) |  |

Constructs a WTrajectoryFrustums.

Parameters

  path | List of poses on a trajectory. Takes std::vector<Affine<T>> with T == [float | double]
  fov | Field of view of the camera (horizontal, vertical).
  scale | Scale of the frustums.
  color | Color of the frustums.

Displays frustums at each pose of the trajectory.
