This weekend I created a scene of Sunderban River Delta. This delta is the house of live Bengal Tigers, Sharks, and Seagulls.
You can choose the Game View from the options on the right-top which allows you to walk on the delta and water using W, S, A, D keys of your keyboard just like any other FPS game. Or you can simply press F key to toggle between Bird View and FPS View.
You can also play with Day shader to change the day or evening time of the day. You can also turn off Ocean shader. When Ocean shader is off I use Simplex Noise to create ocean waves which is also interesting to observe.
I have started experimenting with WebXR so you can also try it in Oculus Quest. The VR mode can be turned on by clicking on the VR icon on the right- bottom side. It works only with Firefox Reality browser in Oculus
