3.1. OpenGL functions in Windows NT
As described in the previous chapter, OpenGL in Windows NT also contains more than 100 library functions. These functions are named in a certain format, that is, each function starts with GL. In addition to basic OpenGL functions,
Wgl–windows OpenGL Expansion Layer
The WGL extension consists of a set of functions (Wglcreatecontext, Wgldeletecontext etc.) and structures (such as Pixelfo Rmatdescriptor, glyphmetricsfloat) etc. Thus every OpenGL implementation has a platform-specific portion which has to is set up and used according to the Particul AR platform.

1. Check whether the graphics card of the Local Machine supports OpenGL. The confirmation method is as follows:
Search for the following two files in the system directory (c: \ windows \ system32 by default for WINXP:
Opengl32.dll and glu32.dll, if any, indicate that your video card has implemented the

---- Scientific computing visualization, computer animation and virtual reality are currently three hot spots in computer graphics. The core of these three hot spots is 3D Realistic Graphics. Since OpenGL (opengraphicslibrary) is cross-platform, simple, efficient, and fully functional, it has become a de facto industrial standard in 3D graphics production methods. Since windowsnt3.51 supports

As is known to all, OPENGL is a state machine with many different states. We can use an array of attributes to save/restore a set of states. There are 20 groups of server property groups and 2 groups of client property groups.about what properties are in these attribute groups.

OpenGL sdks on Windows platforms are implemented by Microsoft, and SGI also implements a set of OpenGL sdks. Some friends on the Internet say that SGI's OpenGL is good, so I had the idea of installing OpenGL for SGI, so I had this article.I. Objective: To install SGI
. however, I think there is a way for ARB to bypass and there are uncertain messages. ms transfers the default OpenGL implementation to d3d. the manufacturer's ICD driver was not blocked. at the same time, there is a restriction that if OpenGL is used, Vista's fancy interface cannot be used. But it doesn't matter to me. I hate very fancy interfaces. You can simply customize them. For example, gnome. I like

OpenGL is only a standard, its implementation is generally brought in the operating system, just make sure that the graphics card driver is new enough to use. If you need to use OpenGL directly in your program, there are a lot of very nasty preparations to do. To skip these jobs, you can use a utility library, the new point has glew, because open source so the installation is relatively convenient (big deal
For OpenGL developers, the advent of VMware Workstation 12 did bring a lot of "surprises", and the VMware Workstation 12 had a big boost to OpenGL's support version.Prior to the release of VMware Workstation 12, only basic support for Opengl2.1,vmware Workstation 12 for OpenGL supported version OpenGL3.3, known as the core protocol interface currently supporting OpenGL3.3.The students who reinstall the sy

I was going to write some introductory and conceptual articles on OpenGL. Who knows that work is getting very busy at once, and people become lazy... but at last they have some free time on the Spring Festival holiday. Let's continue with the unfinished business. What is required for OpenGL development in Windows: If you use vs to develop
If you want to use OpenGL for development in Windows, you will encounter a problem. The OpenGL version provided by Microsoft is 1.1, and the later version is not provided. (why? Because people want to promote their own Dx and despise him !), If you want to use some advanced functions, you can only use OpenGL extensions
