5/5 - (3 votes)


This assignment is intended to be a gentle introduction to graphics programming.
The goal is to write a very simple application that uses the basic features of the
OpenGL, and some simple interaction with what is drawn on the screen.
The application will draw a single square in the center of a window, and
should allow a user to resize, move and rotate this square. The color of the square
should optionally change based on the keyboard input.

Basic Features (75 points):

• Installing all libraries.
• Drawing a square that moves when the user clicks a drags their mouse.

Required Features (20 points):

• (5) Translating only when the user drags on the square’s interior (not the
edge or outside the square)
• (5) Scaling the square when the user drags on the edges
• (10) Rotating the square when the user drags on the corners

Extra Features:

(5) Changing something visually when the user presses the keyboard
(10) Texturing the square
(10) Supporting both a square and triangle
(5) Graphical indicator of what motion is being performed.
(5) Animating the square on it’s own
(5) Multiple squares
(5) Maintaining the square’s shape when the window aspect ratio changes

Submission Details:

Submission should be in the form of a link to a webpage. The web page must contain
an image of your program in progress. A short description (~1 paragraph) of any
difficulties you encountered. A zip file with all the code needed to compile your
project and a working executable.
Optionally, you may submit an image of an artistically interesting image resulting
from your work. Sufficiently “interesting” pictures will be awarded 5 points, the best
in the class 10 additional points.

Getting Started:

You will need the starter code, which is available from the course webpage.
You will also need to download SDL: has
Window and Mac binaries.
On Ubutun you need to install libsdl2-dev
e.g., sudo apt-get install libsdl2-dev
OpenGL should come installed already in your system (see However, please make sure you
have update drivers, and a fairly recent computer.
Mac users will have to download Xcode to get GCC etc.

If you are compiling on Windows using MSVS the compiler flags should already be
set for you. On OSX or Linux, be sure to specify that you need to link against GLEW,
GLUT and opengl.
OS x:
g++ Square.cpp glad/glad.c -framework SDL2 -framework OpenGL -o
g++ Square.cpp glad/glad.c -lSDL2 -lSDL2main -lGL -o square
Be sure to include both SDL2 and SDL2main when linking. Be sure to include both
Square.cpp and glad/glad.c when compiling.


Rotation is much more difficult than the rest. Get everything else working first,
ignoring rotation! Rotation will complicate how you draw the square and how you
detect which operation to perform.
