The simulation team at Open Robotics is happy to announce another major release of Ignition, code named Edifice! This is the fifth major release of Ignition, following Dome, Citadel, Blueprint and Acropolis.
Edifice is a short-term release supported until March 2022.
Here are a few highlights since Dome’s release 6 months ago:
Depot world : Try out the Edifice demo world, which showcases lots of new features at once, using the latest rendering features, as well as new sensors and controllers!
Ignition Utils : There’s a new library in the Ignition family, Ignition Utils, which provides various tools and utilities that are useful to all libraries (and also external projects!), without bringing in any extra dependencies.
Rendering & Sensors : New visual effects and sensor features
- Custom engines : Full interface for using custom rendering engines.
Sky : Add a sky to your worlds using SDFormat’s
- Lightmap : Support lightmap textures for efficient prebaked global illumination, see this example model.
- Light intensity : Lights now have an new intensity parameter that can be modified at runtime.
- Render order : It’s now possible to set the preferred render order for overlapping polygons to resolve z-fighting.
- Thermal camera : A thermal camera sensor that supports objects with uniform or variable surface temperatures.
- Particle effects : Full support for particle emitters, which affect sensors like depth cameras and lidars in a realistic way. Try it out with ign gazebo particle_emitter.sdf.
- Laser retroreflection : Objects detected by Lidar can have custom retroreflection. Try ign gazebo gpu_lidar_retro_values_sensor.sdf.
- Logical audio sensor : New sensor that acts as a microphone to check if audio was detected coming from audio sources in the world.
- Optical tactile sensor : Sensor that measures contact normals using a depth camera and a contact sensor.
GUI : Lots of new GUI features and widgets
- Lights : Insert, configure and visualize lights through the graphical interface or using Ignition Transport.
- Tape measure : Measure distances in the 3D scene by clicking on them.
- Joint controller : A joint position controller widget, try it out with the NAO robot on this world.
- Collision visualization : View collision shapes on the graphical interface in order to better introspect running simulations.
- Screenshot : Take screenshots of running simulations and save them to disk with the click of a button.
- Physics parameters : Configure real time factor and step size from the GUI.
Ackermann drive : There’s now an Ackermann steering plugin, try it out with ign gazebo ackermann_steering.sdf.
Mecanum drive : There’s also a Mecanum drive plugin, try it out with ign gazebo mecanum_drive.sdf.
Capsule and ellipsoid : Besides box, sphere and cylinder primitives, Ignition now also supports capsules and ellipsoids. Try out
ign gazebo shapes.sdf.
Non-SDF models :
libSDFormatnow provides API hooks that can be used to parse models in custom formats.
Heightmaps : Visualize terrains, and soon collide with them too!
Names with spaces : Full support for entity names containing spaces.
COLLADA exporter : Generate a COLLADA mesh from a simulation.
Model inter-dependencies : Models uploaded to Ignition Fuel can easily reuse assets from other models.
Easier migration from Gazebo classic : New APIs and tutorials to aid users in migrating from Gazebo classic to Ignition Gazebo.
In case you missed our March Community Meeting, check it out to see live demos of several of these features!
The currently supported platforms are:
- Ubuntu Bionic (18.04) and Focal (20.04)
- MacOS Catalina (headless mode only)
- Windows (support for some libraries)

We’d like to give especial thanks to the contributors who helped us review Edifice tutorials during the Tutorial Party:
Ammaar Solkar (who reviewed an amazing total of 103 tutorials!)
The next release, Ignition Fortress, is scheduled to be released on September 2021. Keep an eye on the roadmap for what’s coming up, and let us know what features you’re interested in!
