The CVC lab and Virtual KITTI use Unity in their projects. They might have some internal tools. The advantage of UE4 is open-source, so that we can fully understand what the engine is doing.

Many researchers have done interesting work using synthetic data (a lot of them are mentioned in this post). This tool just tries to make the creation of virtual world (which can be used by computer vision) easier.

Exactly. That's the goal for this project.

I created a project https://github.com/qiuwch/synthetic-computer-vision trying to summarize works that used synthetic data for computer vision. Might be worth to have a look.

how do you want to create geometry? like loading an obj file and change its position? Unreal.js might worth a try.
