The function glDrawElements is similar to glDrawArrays, but it is designed for use with data in a format similar to an indexed face set. Instead of calling a GL function to pass each individual vertex, normal, texture coordinate, edge flag, or color, you can prespecify separate arrays of vertices, normals, and so on, and use them to construct a sequence of primitives with a single. I have my code compiling and working but I am not sure if it is working just by chance. Clear the window to an arbitrary color. Rotate by the angle "a" and translate to new position, place the link at the new position.
