OpenGL ES 1.0 uses a fixed pipeline, which is a fancy way of saying you use built-in functions to set lights, vertexes, colors, cameras, and more. Without further ado, let’s start learning OpenGL ES!įirst things first – you should know that there are two different versions of OpenGL ES (1.0 and 2.0), and they are very different. If I make any boneheaded mistakes, feel free to chime in with corrections or insights! :] How to render a 3D object with depth testingĬaveat: I am not an Open GL expert! I am learning this myself, and am writing tutorials as I go.How to apply projection and model-view transforms.How to render a simple square to the screen with vertex buffer objects.How to compile and run vertex & fragment shaders. How to get a basic OpenGL app working from scratch.In the process, you’ll learn the following: In this series, you’ll get hands-on experience with OpenGL ES 2.0 and will create a simple “Hello, World” app that displays some simple geometry. One of the reasons why programmers like to use the above frameworks rather than using OpenGL directly is because OpenGL is notoriously difficult to learn.Īnd that’s what this tutorial is for – to make the learning curve a little less steep for beginner OpenGL developers! If you’ve used other framework such as Cocos2D, Sparrow, Corona, or Unity, these are all built on top of OpenGL! OpenGL ES is the lowest-level API that you use to program 2D and 3D graphics on the iPhone. Learn how to use OpenGL ES 2.0 from the ground up!
