Install the IRRLICHT module

This is a run-time visualization system for interactive 3D viewing of Chrono simulations.

Read the introduction to modules for a technical background on the modularity of the Chrono project.

Features

The IRRLICHT module is used to display Chrono simulations in an interactive 3D view. Here are the main features:

  • Supports all visualization shapes specified as assets on Chrono physics objects (bodies, links, etc)
  • The following default mouse and key controls are supported:
    • mouse left button for camera rotation
    • mouse right button for camera x z motion
    • mouse wheel rotation for camera forward/backward
    • press 'i' to see a setting panel,
    • press arrows to have x z camera motion, press page up & down for y vertical motion
    • press 'print screen' to start saving screenshots to disk
  • Contacts can be optionally drawn with vectors in 3D view
  • Link coordinate systems can be plotted on the 3D view

Requirements

  • To run applications based on this module you need the Irrlicht library (i.e. the Irrlicht.dll on Windows)
  • To build applications applications based on this module you must have the Irrlicht SDK installed.

Building instructions

Instructions on how to install the Chrono::Irrlicht library are already reported on the Chrono installation page. They are repeated here in more details.

  1. Download Irrlicht Engine
  2. Unzip in the desired directory.
    For example, here we suppose that to be C:/engine_demos/irrlicht-1.8.4
  3. Repeat the instructions for the full installation
  4. During CMake configuration, set ENABLE_MODULE_IRRLICHT to 'on', then press 'Configure'
  5. Set the directory in IRRLICHT_ROOT: it must contain the path to your unzipped Irrlicht directory.
    In our example, browse to C:/engine_demos/irrlicht-1.8.4
  6. The corresponding IRRLICHT_LIBRARY should be found automatically: it must contain the file of the Irrlicht.lib.
    In our example, browse to C:/engine_demos/irrlicht-1.8.4/lib/Win64-visualStudio/Irrlicht.lib.
  7. Press 'Configure' again, then 'Generate', and proceed as usual in the installation instructions.

How to use it

  • Consult the API section of this module for documentation about classes and functions.
  • Consult the C++ source of demos to learn how to use the functions of this module.
