Prefix and suffix of open gl

  1. 1. By: Farwa Abdul Hannan (12 – CS – 13) Prefix and Suffix of OpenGL OpenGL Library: OpenGL is a software interface to graphics hardware. This interface consists of about 150 distinct commands that are used to specify the objects and operations needed to produce interactive three dimensional applications. It also consists of different routines. Prefix: A prefix is laced at the beginning of the word to modify or change its meaning. It also helps to avoid naming conflicts if two independent groups implement a similar extension. The GLU and GLX routines begin with the prefix GLU and GLX respectively. Suffix: The Ending part of the word that modifies the meaning of the word, in OpenGL suffix represents some datatypes along with their size.
