Function Documentation

◆ Advance()

void chrono::vehicle::ChVehicleIrrApp::Advance ( double  step)

Advance the dynamics of the chase camera.

The integration of the underlying ODEs is performed using as many steps as needed to advance by the specified duration.

◆ ChVehicleIrrApp()

chrono::vehicle::ChVehicleIrrApp::ChVehicleIrrApp ( ChVehicle vehicle,
const std::wstring &  title = L"Chrono::Vehicle",
const irr::core::dimension2d< irr::u32 > &  dims = irr::core::dimension2d<irr::u32>(1000, 800),
irr::ELOG_LEVEL  log_level = irr::ELL_INFORMATION 

Construct a vehicle Irrlicht application.

log_levelIrrlicht logging level

◆ EnableSound()

void chrono::vehicle::ChVehicleIrrApp::EnableSound ( bool  sound)

Turn on/off Irrklang sound generation.

Note that this has an effect only if Irrklang support was enabled at configuration.

◆ SetChaseCamera()

void chrono::vehicle::ChVehicleIrrApp::SetChaseCamera ( const ChVector<> &  ptOnChassis,
double  chaseDist,
double  chaseHeight 

Set parameters for the underlying chase camera.

ptOnChassistracked point on chassis body (in vehicle reference frame)
chaseDistchase distance (behind tracked point)
chaseHeightchase height (above tracked point)

◆ SetChaseCameraPosition()

void chrono::vehicle::ChVehicleIrrApp::SetChaseCameraPosition ( const ChVector<> &  pos)

Set camera position.

Note that this forces the chase-cam in Track mode.

◆ SetSkyBox()

void chrono::vehicle::ChVehicleIrrApp::SetSkyBox ( )

Create a skybox that has Z pointing up.

Note that the default ChIrrApp::AddTypicalSky() uses Y up.

◆ WriteImageToFile()

void chrono::vehicle::ChVehicleIrrApp::WriteImageToFile ( const std::string &  filename)

Save a snapshot of the last rendered frame to file.

The file name extension determines the image format.
