◆ AddLightWithShadow()

irr::scene::ILightSceneNode* chrono::irrlicht::ChIrrAppInterface::AddLightWithShadow ( irr::core::vector3df  pos,
irr::core::vector3df  aim,
double  radius,
double  mnear,
double  mfar,
double  angle,
irr::u32  resolution = 512,
irr::video::SColorf  color = irr::video::SColorf(1.f, 1.f, 1.f, 1.f),
bool  directional = false,
bool  clipborder = true 
)
inline

Add a point light that cast shadow (using soft shadows/shadow maps) Note that the quality of the shadow strictly depends on how you set 'mnear' and 'mfar' parameters as close as possible to the bounding box of the scene.

NOTE: use myapplication.AddShadow(myitem) to enable shadow for an object! Otherwise, use myapplication.AddShadowAll().

◆ DoStep()

void chrono::irrlicht::ChIrrAppInterface::DoStep ( )
virtual

Call this function inside a loop such as.

   while(application.GetDevice()->run()) {...}

in order to advance the dynamics by one timestep. The value of the timestep can be set via SetTimestep(). Optionally, you can use SetTryRealtime(true) if your simulation can run in realtime; this will enforce soft real-time. Alternatively, to use ChSystem::DoStepDynamics() directly in the loop, use SetStepManage(false).

◆ DrawAll()

void chrono::irrlicht::ChIrrAppInterface::DrawAll ( )
virtual

Call this function inside a loop such as.

   while(application.GetDevice()->run()) {...}

to draw all 3D shapes and GUI elements at the current frame.

Reimplemented in chrono::vehicle::ChVehicleIrrApp.

◆ DumpSystemMatrices()

void chrono::irrlicht::ChIrrAppInterface::DumpSystemMatrices ( )

Dump the last used system matrices and vectors in the current directory, as 'dump_xxxx.dat' files that can be loaded with Matlab for debugging, benchmarking etc.

It saves M mass matrix, Cq jacobians, E compliance as Matlab sparse matrix format, and known vectors fb, bi as column Matlab matrices.

◆ SetFonts()

void chrono::irrlicht::ChIrrAppInterface::SetFonts ( const std::string &  mfontdir = GetChronoDataFile("fonts/arial8.xml"))

Set the fonts to be used from now on.

Note that the font must be in the XML format of Irrlicht - this can be generated using a tool provided with Irrlicht.

◆ SetStepManage()

void chrono::irrlicht::ChIrrAppInterface::SetStepManage ( bool  val)
inline

If set to true, you can use DoStep() in the simulation loop to advance the simulation by one timestep.

Otherwise, you have to handle the time stepping by yourself, e.g. by calling ChSystem::DoStepDynamics(). Default: true.

◆ SetTimestep()

void chrono::irrlicht::ChIrrAppInterface::SetTimestep ( double  val)

Set/Get the time step for time integration.

This value is used when calling DoStep() in a loop, to advance the simulation by one timestep.
