◆ AddCamera()

int chrono::irrlicht::ChVisualSystemIrrlicht::AddCamera ( const ChVector3d pos,

)

Add a camera in an Irrlicht 3D scene.

The camera rotation/pan is controlled by mouse left and right buttons, the zoom is controlled by mouse wheel or rmb+lmb+mouse, the position can be changed also with keyboard up/down/left/right arrows, the height can be changed with keyboard 'PgUp' and 'PgDn' keys. Optional parameters are position and target. Has no effect, unles called after Initialize().

Reimplemented from chrono::ChVisualSystem.

◆ AddGrid()

)
overridevirtual
