Detailed Documentation

Trajectories.

This 3D Widget represents a trajectory. :

Construction

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

Constructs a WTrajectory.

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.

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.
