FWsim Fireworks Simulator
Create your own fireworks, add your favourite music, and create music-synchronous shows. Add real 3D buildings, or import 3D models from the internet.

  • 1,000 different firework effects already included
  • Flexible effects editor: Take simple components and chain them together - just like real fireworks manufacturers do.
  • HD video export with smoke simulation
  • Real sounds, recorded from actual fireworks
  • Realistic simulation: Fireworks Companies in 18 countries use the same simulation engine for planning & visualization
  • Create gigantic shows: FWsim is optimized for performance. All the scenes you see in the trailer can be played on an average gaming PC.

Coming with the Steam release:

  • More realistic smoke simulation
  • Larger 3D worlds
  • Ultra-high quality 4K resolution video export

I love this. Buy the 24 dollar one. You can make your own fireworks and Time limits are no problem.

If development is going so slow why not open source it? Let the community take a crack at it. I know I would play with the rendering engine quite a bit, maybe add in a full physics engine.

Thanks very much for your ongoing support.
Unfortunately, development of the new FWsim version is delayed, and we predict a release no earlier than 2018. We want the Steam version to be really good, which takes a lot of time.

If you want to test the current version of FWsim, you can do that at .
Thanks again for your support!

According to one of the staff members at FWSim, "Development has started but is going very slowly."
