Python bindings for the event camera simulator can be found here. We now also support GPU support for fully parallel event generation!
- Accurate event simulation, guaranteed by the tight integration between the rendering engine and the event simulator
- Inertial Measurement Unit (IMU) simulation
- Support for multi-camera systems
- Ground truth camera poses, IMU biases, angular/linear velocities, depth maps, and optic flow maps
- Support for camera distortion (only planar and panoramic renderers)
- Different C+/C- contrast thresholds
- Basic noise simulation for event cameras (based on additive Gaussian noise on the contrast threshold)
- Motion blur simulation
- Publish to ROS and/or save data to rosbag
Below is a table summarizing the different rendering engines available to date, with their respective properties.

| MultiObjects2D | 2D | No | Yes | No | ▓▓▓░░ |
| PanoramicRenderer | 2D (rotation only) | Yes | No | Yes | ▓▓▓▓░ |
| PlanarRenderer | 2.5D (planar) | Yes | No | Yes | ▓▓▓▓░ |
| OpenGLRenderer | 3D | Yes | Yes | No | ▓▓▓▓▓ |
