Every chapter will also conclude with a link to the full code listing up to thatpoint. You can refer to it if you have any doubts about the structure of thecode, or if you're dealing with a bug and want to compare. All of the code fileshave been tested on graphics cards from multiple vendors to verify correctness.Each chapter also has a comment section at the end where you can ask anyquestions that are relevant to the specific subject matter. Please specify yourplatform, driver version, source code, expected behavior and actual behavior tohelp us help you.
Direct3D and OpenGL are competing application programming interfaces (APIs) which can be used in applications to render 2D and 3D computer graphics. As of 2005[update], graphics processing units (GPUs) almost always implement one version of both of these APIs. Examples include: DirectX 9 and OpenGL 2 circa 2004; DirectX 10 and OpenGL 3 circa 2008; and most recently, DirectX 11 and OpenGL 4 circa 2011. GPUs that support more recent versions of the standards are backwards compatible with applications that use the older standards; for example, one can run older DirectX 9 games on a more recent DirectX 11-certified GPU.
OpenGL has always seen more use in the professional graphics market than DirectX, while DirectX is used mostly for computer games. (The term professional is used here to refer to the professional production and display of graphics, such as in computer animated films and scientific visualisation, as opposed to games where the graphics produced are for the end user's personal, rather than professional, use.) Currently both OpenGL and DirectX have a large enough overlap in functionality that either could be used for most common purposes, with the operating system often being the main criterion dictating which is used; DirectX is the common choice for Windows, and OpenGL for nearly everything else. Some esoteric applications still divide the applicability of the two APIs: doing accelerated 3D across a network connection is only directly supported by OpenGL with OpenGL Extension to the X Window System (GLX), for example.
Wireframe is an excellent magazine that blends developer interviews with practical tutorials such as how to implement various game mechanics in programming languages such as python or even C programming for the original Game Boy! 1e1e36bf2d
