Chapter 1 The Graphics Pipelineupdated April 5, 2.PDTOpen. GL has been around a long time, and from reading all the accumulated layers of documentation out there on the Internet, its not always clear what parts are historic and what parts are still useful and supported on modern graphics hardware.Its about time for a new Open.GL introduction that walks through the parts that are still relevant today.Update Join the Reddit discussion.Opengl Driver For Voodoo 3Dfx' title='Opengl Driver For Voodoo 3Dfx' />Opengl Driver For Voodoo 3dfx HardwareWhat is Open.GL Wikipedia gives a good overview of the purpose and history of Open.GL, but Ill give a quick summary here.In its modern form, Open.GL is a cross platform library for interfacing with programmable GPUs for the purpose of rendering real time 3d graphics.Its use is common in games, CAD, and data visualization applications.It started in the early 9.SGIs proprietary GL Graphics Library that drove the graphics hardware in their high end workstations.A few years later, GLQuake and 3dfxs Voodoo graphics accelerators pushed 3d accelerators into the mainstream, and Open.GL became a standard alongside Microsofts proprietary Direct.PCs. In recent years, the Khronos group has taken stewardship of the Open.GL standard, updating it to support the features of modern programmable GPUs, pushing it into the mobile and online domains with Open.GL ES and Web. GL, and streamlining it in Open.GL 3 by deprecating the outdated features that cluttered earlier versions of the library.Another recent development has been the adoption of general purpose GPU GPGPU libraries, including n.Vidias CUDA and Khronos Open.CL. These libraries implement dialects of C with added data parallelism features, allowing the GPU to be used for general computation without having to work within the graphics oriented framework of Open.GL. However, these GPGPU frameworks dont replace Open.GL since their primary purpose is not graphics programming, they only provide access to a GPUs computation units, ignoring its graphics specific hardware.They can, however, act as accessories to Open.GL. CUDA and Open.CL both can share buffers of GPU memory with Open.GL and pass data between GPGPU programs and the graphics pipeline.GPGPU will be outside the scope of these articles Ill be focusing on using Open.GL for graphics tasks.For these tutorials, Im going to assume youre already a programmer and that you know C, but that you havent necessarily seen Open.GL or done graphics programming before.Knowing at least some basic algebra and geometry will help a lot.Im going to cover Open.GL 2. 0, and avoid discussing any API features that are deprecated or removed in Open.GL 3 or Open. GL ES.If I write enough chapters, I might talk about some of the new features of Open.GL 3 and 4 after I go through the basics.In addition to Open.GL, Ill be using two helper libraries GLUT the GL Utility Toolkit, which provides a cross platform interface between the window system and Open.GL, and GLEW the GL Extensions Wrangler, which streamlines dealing with different versions of Open.GL and their extensions.Where do I get Open.GL, GLUT, and GLEW Open.GL comes standard in some form or another on Mac.OS X, Windows, and most Linux distributions.If you want to follow these tutorials, youll need to ensure your Open.GL implementation supports at least version 2.Mac. OS Xs Open. GL implementation always supports Open.GL 2. 0, at least in software if the graphics card driver doesnt provide it.On Windows, youre dependent on your graphics card drivers to provide Open.GL 2 or later. You can use Real.Techs free Open. GL Extensions Viewer to see what Open.GL version your driver supports.Vidia and AMDs Open.GL drivers support at least Open.GL 2. 0 on all of their video cards released in the past four years.Users of Intel onboard graphics and older graphics cards are less fortunate.For a fallback, Mesa provides an open source, cross platform software Open.GL 2. 1 implementation that works on Windows and almost all Unix platforms.Mesa is also the most common Open.GL implementation on Linux, where it also works with the X server to interface Open.GL with graphics hardware using direct rendering interface DRI drivers.You can see whether your particular DRI driver supports Open.GL 2. 0 by running the glxinfo command from an xterm.If Open. GL 2. 0 isnt supported on your hardware, you can disable the driver to fall back to Mesas software implementation.Vidia also provides their own proprietary Open.GL implementation for Linux targeting their own GPUs this implementation should provide Open.GL 2. 0 or later on any recent n.Vidia card. To install GLUT and GLEW, look for the binary packages on their respective sites.Mac. OS X comes with GLUT preinstalled.Most Linux distributions have GLUT and GLEW available through their package system, though for GLUT, you may need to enable your distributions optional non free package repositories, since its license is not technically open source.There is an open source GLUT clone called Open.GLUT if youre a stickler for such things.If youre a seasoned C programmer, you should be able to install these libraries and get them working in your development environment without any trouble.But before we get our hands dirty with any code, Im going to go over some big picture concepts.In this first chapter, Im going to explain the graphics pipeline and the dataflow of a rendering job.In the next chapter, well write a simple hello world program that draws the contents of an image file to the screen, showing how the pipeline is put into practice.Ever since the early days of real time 3d, the triangle has been the paintbrush with which scenes have been drawn.Although modern GPUs can perform all sorts of flashy effects to cover up this dirty secret, underneath all the shading, triangles are still the medium in which they work.The graphics pipeline that Open.GL implements reflects this the host program fills Open.GL managed memory buffers with arrays of vertices these vertices are projected into screen space, assembled into triangles, and rasterized into pixel sized fragments finally, the fragments are assigned color values and drawn to the framebuffer.Modern GPUs get their flexibility by delegating the project into screen space and assign color values stages to uploadable programs called shaders.Lets look at each stage in more detail.The vertex and element arrays.A rendering job starts its journey through the pipeline in a set of one or more vertex buffers, which are filled with arrays of vertex attributes.These attributes are used as inputs to the vertex shader.Common vertex attributes include the location of the vertex in 3d space, and one or more sets of texture coordinates that map the vertex to a sample point on one or more textures.The set of vertex buffers supplying data to a rendering job are collectively called the vertex array.When a render job is submitted, we supply an additional element array, an array of indexes into the vertex array that select which vertices get fed into the pipeline.The order of the indexes also controls how the vertices get assembled into triangles later on.Uniform state and textures.A rendering job also has uniform state, which provides a set of shared, read only values to the shaders at each programmable stage of the pipeline.This allows the shader program to take parameters that dont change between vertices or fragments.The uniform state includes textures, which are one, two, or three dimensional arrays that can be sampled by shaders.

As their name implies, textures are commonly used to map texture images onto surfaces.They can also be used as lookup tables for precalculated functions or as datasets for various kinds of effects.The vertex shader.The GPU begins by reading each selected vertex out of the vertex array and running it through the vertex shader, a program that takes a set of vertex attributes as inputs and outputs a new set of attributes, referred to as varying values, that get fed to the rasterizer.At a minimum, the vertex shader calculates the projected position of the vertex in screen space.The vertex shader can also generate other varying outputs, such as a color or texture coordinates, for the rasterizer to blend across the surface of the triangles connecting the vertex.Triangle assembly.The GPU then connects the projected vertices to form triangles.
