		<description><![CDATA[In this part we will be doing a bit of simple geometry instancing with a minecraft twist, basically what we are going to do is first generate a volumetric landscape of sorts, then render it using cubes, but not the usual way, we are going to do it as a particle system, which is i guess a little bit more than usual as it involves other stuff than strictly openGL, and since there are a few things i want to try out in this field you will be seeing more of it.
This tutorial assumes that you have all the stuff needed for part 1 and in addition texturing available.]]></description>

		<description><![CDATA[New in OpenGL 3.2 is so called geometry shaders, if you don't know what they are then what the essentially do is allow you to create new or duplicate geometry. Like instead of drawing a bunch of cubes one after another you could just render a point cloud and let the geometry shader "upgrade" them to cubes, which is probably how i would render minecraft i where it's creator.]]></description>
