## ◆ WTrajectory()

cv::viz::WTrajectory::WTrajectory | ( | InputArray | path,
|  | int | display_mode = `WTrajectory::PATH`,
|  | double | scale = `1.0`,
|  | const Color & | color = `Color::white()`
| ) |  |

Constructs a WTrajectory.

Parameters

  path | List of poses on a trajectory. Takes std::vector<Affine<T>> with T == [float | double]
  display_mode | Display mode. This can be PATH, FRAMES, and BOTH.
  scale | Scale of the frames. Polyline is not affected.
  color | Color of the polyline that represents path.

Frames are not affected. Displays trajectory of the given path as follows:

- PATH : Displays a poly line that represents the path.
- FRAMES : Displays coordinate frames at each pose.
- PATH & FRAMES : Displays both poly line and coordinate frames.
