IntroductionIn the previous tutorials, many of the scenes have appeared a bit bland. This tutorial will explain how lighting can be added to your scenes. This increases the overall realism and l

IntroductionIn the last tutorial, we spoke about how to work with color blending.We found out that this can be extremely useful for transparency. This tutorial will show you how to create a

RequirementsBefore you can begin programming OpenGL ES for the PocketPC, you will need the following :Embedded Visual C++ 4.0Embedded Visual C++ 4.0 Service Pack 4Pocket PC 2003 SDKAn OpenGL E

IntroductionIn many of your programs you will need the option of accepting keyboard input. This tutorial will explain how to capture messages sent from the keyboard.If you are using GLUT|ES,

IntroductionYou may have noticed that when you open up the keyboard at the bottom of the screen, the window is resized and the shape moves off the top of the screen. As the GLUT|ESlibrary always

IntroductionIn the real world, if you have many objects of the same size at different distances from you, you will notice that the further away the objects are, the smaller they appear.In th

IntroductionIn the previous tutorial, we added light to a scene. This light did not come from any particular direction.This tutorial will deal with directional lighting. This allows us to ta

IntroductionThis tutorial is going to be slightly different to the previous tutorials. Instead of showing you something new, we are going to be seeing how you can use your knowledge gained in th

IntroductionThis tutorial will deal with the fog effect.This can be extremely useful in certain applications. Imagine that you are creating a game where you travel across a country side. You o

What is Masking?You may find yourself having an OpenGL scene with some background. You may also have some object, text or character which is made up of an image. The problem here is that the obj

IntroductionIn the real world, reflections are always evident. This tutorial will explain how to create reflections using the stencil buffer.How does the Stencil Buffer Work?The stencil

IntroductionIn the previous tutorial, we used 2 images to create transparency. This was achieved with blending and is known as masking.This tutorial will explain how to create the same effec

IntroductionThe first step in creating any OpenGL application is to create an OpenGL window on which you can display your program. This tutorial will explain how to create a window using theVinc

What is OpenGL ES?"OpenGL ES is a royalty-free, cross-platform API for full-function 2D and 3D graphics on embedded systems - including handheld devices, appliances and vehicles. It is a well-defi

What is Orthographic Projection?There are 2 ways to view things. One is by viewing objects in an Orthogrpahic manner and the other is viewing objects in a perspective view.Ig you have ever l

IntroductionYou may find yourself needing to transform your primitives in various ways.OpenGL ES provides 3 ways of transforming your primitives :ScalingTranslationRotationScaling wi

IntroductionUp until now, any primitives that you displayed would appear on top of each other depending on the order that they were displayed in. This would occur, even if the primitives had dif

IntroductionNow that we have the ability to process depth and we can display primitives in a perspective view, we are able to create 3D objects.This tutorial follows on from the previous tut

IntroductionAfter adding lighting, you may still not be happy with the realism of your objects.This tutorial will show you how to add textures to your polygons. This is known as texture mapp

IntroductionIn the previous tutorial, we dealt with how to load a bitmap and display it as a texture on an object. You were briefly introduced to the glTexParameterf function.This tutorial w

IntroductionThis tutorial will discuss color blending.Color blending is useful for effects such as transparency eg. glass, water, windows, etc.An essential part of blending is the alpha va

IntroductionIn many of your programs you will need the option of accepting pointer input. This tutorial will explain how to capture messages sent by using a pointing device on the window.If

IntroductionIn the previous tutorials, nothing has been displayed on the screen. This tutorial will explain how to setup your OpenGL ES window to allow drawing of primitives.If you are using

IntroductionIn the previous tutorial, you learnt how to draw primitives. These primitives were a little dull as they were all white. This tutorial will show you how to add color and shading to y

IntroductionIn tutorial 10, you will have noticed that when the primitives rotate, their backs are also rendered. When creating a 3D object such as the box in the previous tutorial, we do not

This project renders fonts using OpenGL ES and the FreeType library. The FreeType library uses font hinting, which makes the fonts look better than your average anti-aliased fonts. This project is p
