Beginning OpenGL |
| Welcome to our new series of tutorials about OpenGL, the greatest API for real-time rendering. While reading this series of tutorials you also learn more about Programming There are a lot of other tutorials about OpenGL around the net but you find this series a lot different. I tried to make these tutorials easy to follow and very practical.

OpenGL Primitives |
| Here we are actually going to start using OpenGL and draw some shapes. OpenGL can draw a few primitives like points, lines, triangles and polygons. Primitives are the only visible things on a scene and you should draw everything using them. We start drawing some simple shapes in this tutorial.

Viewing And Transformations |
Transformations are a very important part of Computer Graphics. If you understand it well, you can use it to create a lot of eye candy effects that later we talk about (like shadowing, billboards and...) how ever simplest use of transformations are in positioning and rotating the objects and the camera.

Particle Systems |
| Particle systems are one of the most amazing parts of games. All the effects like rain, fire, smoke, and etc, can be created using particle systems. Creating a realistic particle system may be difficult but main idea is very simple. In this tutorial we are going to create a simple particle system and use it to simulate a smoke effect.

Environment Mapping |
| Instead of specifying texture coordinates, you can let OpenGL to generate it for you. You can create a lot of exciting effects using this technique, here we show you how to use the automatic texture generation to simulate a reflection.
