MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -What is OpenGL? OpenGL is the name for the specification that describes the behavior of a rasterization-based rendering system. It defines the API through which a client application can control this system. The OpenGL rendering system is carefully specified to make hardware implementations allowable.

Detailed explanation-2: -The OpenGL Utility Library (GLU) contains several routines that use lower-level OpenGL commands to perform such tasks as setting up matrices for specific viewing orientations and projections, performing polygon tessellation, and rendering surfaces. This library is provided as part of every OpenGL implementation.

Detailed explanation-3: -OpenGL (Open Graphics Library) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering.

Detailed explanation-4: -A fairly complete list of features added in different versions of the OpenGL specification is as follows: OpenGL 1.1. Vertex array, polygon offset, RGB logic operation, texture image formats, texture replace environment function, texture proxies, copy texture, texture subimage, texture objects.
