PPT-OpenGL A Brief Overview What is OpenGL?

It is NOT a programming language It is a Graphics Rendering API consisting of a set of functions with a well defined interface Whenever we say that a program is OpenGLbased or OpenGL applications we mean that it is written in some programming language such as CC or Java that makes calls to one or more of OpenGL libraries. Graphics with OpenGL/GLUT What is OpenGL? • OpenGL ( Open G raphics L ibrary) • A software interface to graphics hardware • a standard specification defining a cross - language, c Graphics Programming.
