1. Graphics Programming using OpenGL

2. OpenGL is a software interface that allows the programmer to create 2D and 3D graphics images. This interface consists of more than 700 distinct commands OpenGL is independent of the hardware, operating, and windowing systems in use

3. Features in OpenGL 3D Transformations - Rotations, scaling, translation, perspective Colour models - Values: R, G, B, alpha. Lighting - Flat shading, Gouraud shading, Phong shading Rendering -Texture mapping Modeling - non-uniform rational B-spline (NURB) curves, surfaces

4. The OpenGL Utility Library (GLU) provides many of the modeling features, such as quadric surfaces and NURBS curves and surfaces. GLU is a standard part of every OpenGL implementation. GLUT (Graphics Library Utility Toolkit), a portable toolkit.
