Aug 08, 2011 · OpenGL Basics • The main use: Rendering • OpenGL can render: – Geometric primitives – Bitmaps and images Rendering is the process of generating an image from a model (or models in what collectively could be called a scene file), by means of computer programs -----Wikipedia
OpenGL was primarily designed to be able to draw high-quality images fast enough so that an application could draw many of them a second, and provide the user with an interactive application, where each frame could be customized by input
OpenGL is a library for drawing, or rendering, computer graphics By using OpenGL, you can create interactive applications that render high-quality color images composed of 3D geometric objects and images OpenGL is window- and operating-system independent As such, the part of your application that does rendering is platform independent
What is OpenGL? • Graphics Library – for Silicon Graphics – available on all major graphics computers • Provides graphics primitives – takes care of all basic tasks (line, polygon, perspective, Gouraud shading ) • Link with your programs as a normal C library
GLSL (“OpenGL Shading Language”) allows (normally small chunks of) code to run in the graphics hardware This code executes substantially faster than if it were executed in the CPU, as would happen in normal programming 1 1 6OpenGL versions At time of writing, OpenGL 4 5 is the latest version Mac OS X 10 11 only supports OpenGL 4 1 1

Appendix C, "OpenGL and Window Systems," briefly describes the routines available in window-system specific libraries, which are extended to support OpenGL rendering WIndow system interfaces to the X Window System, Apple MacIntosh, IBM OS/2, and Microsoft Windows OpenGL Programming Guide (Addison-Wesley Publishing Company)
This section describes the OpenCL C programming language used to create kernels that are executed on OpenCL device(s) The OpenCL C programming language (also referred to as OpenCL C) is based on the ISO/IEC 9899:1999 C language Specification (a k a “C99 Specification” or just “C99”) with specific extensions and restrictions
Guile-OpenGL uses the dynamic foreign function interface provided by Guile 2 0, providing access to OpenGL without any C code at all In fact, much of Guile-OpenGL (and this manual) is automatically generated from upstream API specifications and documentation We have tried to do a very complete job at wrapping OpenGL, and additionally have

Can you use C++ in OpenGL?
Since OpenGL is a graphics API and not a platform of its own, it requires a language to operate in and the language of choice is C++ .How much C++ is required for OpenGL?
You don't need to be a master in C++ to start learning OpenGL. As a matter of fact, you don't even need to know C++. If you know a decent amount of C, you should be fine to start working with OpenGL. OpenGL is not a programming language, it is an API.Is OpenGL for C or C++?
The OpenGL libraries are written in C and allows for many derivations in other languages, but in its core it remains a C-library.So let's get started
