The everchanging terrain graphic
If you refresh the Voneum home page you will see that the graphic in the top right quadrant updates.
This could be achieved by having the server choose a new image each time the page loads.
There are actually no stored images. This graphic is randomly generated in your browser.
Many games require "worlds" to play in. To create the terrain for these worlds, developers often rely on Procedural generation algorithms.
That's how this voneum graphic is created. In this case something called Simplex noise is used, but there are many ways of doing the same thing.
You can prove the image is created "on-the-fly" by resizing the browser window. The graphic will update. If you were to check the F12 Developer Tools you would see that no calls are being made to the server while this is happening.
So, is there a point to any of this?
Nope!
It is just a bit of fun.
