I have no problem if I add the following 2 lines:
auto vis_irr =
std::static_pointer_cast<ChTrackedVehicleVisualSystemIrrlicht>(vis);
irrlicht::tools::drawSegment(vis_irr.get(),
vehicle.GetChassis()->GetDriverPos(),
vehicle.GetChassis()->GetDriverPos() +
ChVector<>(0, 0, 10));
after the call to vis->Render() and before the call to vis->EndScene() in
demo_VEH_M113.cpp<https://github.com/projectchrono/chrono/blob/main/src/demos/vehicle/tracked_models/demo_VEH_M113.cpp>.
Could you please try that? If that doesn’t work for you, please provide more
information (Chrono version, Irrlicht version, OS, compiler, etc)

Hi,
I didn't make the call between BeginScene and EndScene, it is working now but
only when I make the call before vis->Render().
Thank you very much for a quick and helpful answer!

Hi Meninstick,
I cannot reproduce this issue. Are you sure you are making the call to
drawSegment() *between* the calls to BeginScene() and EndScene()?
Also, use the 2nd form you have below. Casting to ChVisualSystemIrrlicht will
likely not work (because of some multiple inheritance for the vehicle
visualization systems).

Subject: [chrono] DawSegments not showing line
Hi,
I'm trying to visualize certain points on a tracked vehicle at runtime.
DrawSegment is not working for me, maybe I've misunderstood something. Ive
tried at various locations but nothing shows up.
I would be really thankful for any guidance.
auto vis = chrono_types::make_shared<ChTrackedVehicleVisualSystemIrrlicht>();
.
.
.
.
while (vis->Run()) {
//irrlicht::tools::drawSegment(std::static_pointer_cast<irrlicht::ChVisualSystemIrrlicht>(vis).get(),
vehicle.GetChassis()->GetDriverPos(), vehicle.GetChassis()->GetDriverPos() +
ChVector<>(0, 0, 10));
irrlicht::tools::drawSegment(vis.get(), vehicle.GetChassis()->GetDriverPos(),
vehicle.GetChassis()->GetDriverPos() + ChVector<>(0, 0, 10));
