Simple line and arrows

[ga72kud]

Hi, thank you for the excellent package. Is there a simple and fast solution for visualizing a line and arrows (should I use polygon of geometry basics?)? I want to visualize a point cloud and compute the nearest neighbor graph.
3dimensional Line, in the documentation, is a 2dim line mentioned

Seems like to have use shaft = Cylinder(zero(Point{3, Float64}), Point(0.0, 0.0, 10.0), 0.1)
setobject!(vis, shaft)

Hi @ga72kud,

For simple line segments, you can use something like this:

function show_path(vis::Visualizer, points::Matrix{Float64})
    points = collect(eachcol(points))
    material = LineBasicMaterial(color=colorant"yellow", linewidth=2.0)
    setobject!(vis["path"], Object(PointCloud(points), material, "Line"))
    nothing
end

For arrows, see this JuliaRobotics/RigidBodyDynamics.jl#589 (comment).
