v2.0

This update adds the following improvements:

1. Event simulation model
   • Model dark current
   • Accurately model the band-limiting behavior of the pixel with a 5th-order Non-Linear Time-Invariant (NLTI) Low-Pass Filter (LPF)

It also includes a Blender 3.4.0 Python wheel compiled with CUDA Toolkit 11.8 and OptiX 7.3.0 for Linux and Python 3.10.

v1.0

This initial release incorporates the following improvements to the official ESIM:

1. Event simulation model
   • Improve the overall event simulation accuracy by accounting for additional edge cases
   • Improve the refractory period model by explicitly resetting the pixel reference intensity and timestamp at the end of the refractory period
   • Desynchronize initial event generation across pixels by randomly initializing pixel reference timestamps
   • Model junction leakage, which increases the rate of ON events and decreases the rate of OFF events
   • Modify the pixel-to-pixel contrast threshold variation model to be time-independent
   • Merge feature/color branch to support color event cameras
2. Rendering engine
   • Support Blender as a rendering engine
   • Support Unreal Engine 4.27.2 with a modified UnrealCV plugin
3. Camera trajectory
   • Circumvent singularities in interpolating quaternion orientations by supporting rotation vector/angle-axis orientation representation in the trajectory CSV for interpolation
4. Miscellaneous
   • Fix various bugs & installation errors
