		<description><![CDATA[We can generate 3D faces from 2D flat images. Using OpenGL this can be challenging, after all it is not a lot more than a primitive triangle rendering API. The technique we will use in this tutorial is very similar, if not nearly identical, to terrain generation in our previous tutorial. We got the original face image from [&#8230;]]]></description>

		<description><![CDATA[In this tutorial we will render terrains. Essentially a terrain is a complex 3d model.  It conists of vertexes, faces, texture coordinates, normal vectors etc.  Al though it is possible to load complete models such as Wavefront OBJ models, it is generally better to dynamically generate them.  First, we must define a terrain (or variation in [&#8230;]]]></description>

		<description><![CDATA[You will need to change the previous code for this tutorial. OpenGL is used to communicate with the Graphical Processing Unit, so by default it does not contain keyboard control. You will need a library to communicate with the keyboard. We can use SDL (which we have been using all this time) to take keyboard [&#8230;]]]></description>

		<description><![CDATA[In this short tutorial we will demonstrate how to do blending in OpenGL. You may notice in the final code we load two different textures:  one background texture and one object texture (glass). The background will be a normal square. The cube will blended on top of it, as if it is underwater We have [&#8230;]]]></description>

		<description><![CDATA[To create a fire/explosion like effect we can use the same particle engine as in the previous tutorial (starfield) but we have to modify the code a little bit. All particles move upwards; in addition, every particle has to moves at a different speed, and start from the same point. All code below. You may [&#8230;]]]></description>

		<description><![CDATA[&#160; We introduce a simple particle engine. A particle engine can be used for many purposes in 3d graphics such as fire, explosions, lasers, stars and many other fun things! To make a particle engine, we need to have a particle set.  The set consists of N elements where each elements represents a star. A [&#8230;]]]></description>
