+An interactive demo for controlling the camera similar to to a first person shooter control using `w,a,s,d` and `q` and `e` for up and down. Using the left click on the mouse you can rotate the camera. Here is an [example](https://imgur.com/VYda2UF) of the sort of motion you can generate.
 
 ## Notes
 All these examples were developed and tested on Ubuntu 18.04 with cuda 11.0, NVIDIA drivers
 450.36.06 and using a NVIDIA TITAN RTX .
