COMPUTER GRAPHICS

In this assignment, you are to create an OpenGL 2D scene of your choosing with the following requirements:

1) The scene should make sense and be intentional (not a bunch of random shapes/colors).

2) Must have at least five distinct shapes (circle is a shape).

3) Must have at least one circle using a for loop and trigonometry.

4) Must have at least five unique colors.

The zipped file assignment0.zip contains a Visual Studio 2013 C++ solution to get you started, including a skeleton file named assignment0.cpp where all your code should go. Make sure you have Visual Studio
