Description: This the third tutorial in the Foundation section. This tutorial covers the basics of drawing some simple 2D polygons such as triangle, pentagon, rectangle etc. We will make use of the code that we had generated in the previous section. We ll cover some important topics such as Clipping Area, Viewports, Vertex and the Primitives in OpenGL such as the point, line, triangle, polygon, quads etc. We ll write a program that is menu driven and draws points, triangles, lines, quads etc.
