Cool demo and writeup. Why's is it so sparkly though?

There's a specular light positioned above the terrain, which adds the sparkle (light3 in https://github.com/felixpalmer/lod-terrain/blob/master/js/sh...). If you want to play around with changing the light etc, you can use Mozilla's awesome in-browser GLSL editor (currently in FF beta): https://hacks.mozilla.org/2013/11/live-editing-webgl-shaders...

Probably aliasing due to undersampling.

Terrain rendering is probably one of the things where GPU-based raymarching really is an option nowadays.

Probably is - I was astonished when I first saw this raymarched procedural terrain at shadertoy: https://www.shadertoy.com/view/4slGD4

::rant:: Crashed firefox( latest version ); tried chrome, loads forever and then doesn't work. For whom is this made, if it doesn't work on my i5 with a decent gpu?

Mac users? :) Sorry!

Runs ok (well, 12fps!) here on firefox on an iMac. Just black on my centOS laptop with intel graphics, I admit, but loads of gl things don't run on that.
