Amazing shader demo

[Richard Russell]

This is a shader demo by Sebastien Durand (https://www.shadertoy.com/view/fsXcR8) adapted for BBC BASIC for SDL 2.0. Everything except the salt lake floor is rendered in real-time by shader code, there are no pre-rendered textures! I am amazed that this is possible, needing only a mid-range GPU; a real tour de force.

If you have a suitable browser you can run it yourself here and change the viewpoint by moving your mouse.

That's astonishing that that can be run, in an interpreted language, within a browser....

Socks well and truly blown off.

To be fair, the "interpreted language" does very little once the shaders have been compiled, being responsible only for testing the mouse coordinates and feeding them and the current TIME to the GPU. Task Manager was reporting something like 0.3% CPU usage and 99% GPU usage!
