chrono::vehicle::ChVehicleVisualSystemIrrlicht Class Reference

Description

custom event receiver for chase-cam control

Customized Chrono Irrlicht visualization for vehicle simulations. This class implements an Irrlicht-based visualization wrapper for vehicles. This class extends ChVisualSystemIrrlicht and provides the following functionality:

• rendering of the entire Irrlicht scene
• custom chase-camera (which can be controlled with keyboard)
• optional rendering of links, springs, stats, etc.
