Detailed Documentation

This 3D Widget represents a trajectory using spheres and lines.

where spheres represent the positions of the camera, and lines represent the direction from previous position to the current. :

Construction

WTrajectorySpheres(
    InputArray path,
    double line_length = 0.05,
    double radius = 0.007,
    const Color& from = Color::red(),
    const Color& to = Color::white()
    )

Constructs a WTrajectorySpheres.

Parameters:

path	List of poses on a trajectory. Takes std::vector<Affine<T>> with T == [float | double]
line_length	Max length of the lines which point to previous position
radius	Radius of the spheres.
from	Color for first sphere.
to	Color for last sphere. Intermediate spheres will have interpolated color.
