This coursework is worth 25% of the total module mark
Set: 7th October 2011 Due: 11th November 2013 by 10AM
Learning Outcomes:
1) GLUT framework
2) Drawing primitives in OpenGL
3) Rotation transformation
4) Basic collision detection
5) Introduction real-time graphics

7. Description
You are to build a simple 2D game (with some 3D effects) in
OpenGL and the
by using GLUT toolkit to assist you. The game is loosely based
on the classic
80s game ‘Asteroids’.
A mock-up of the game screen is shown in figure 1 below. The
game will be
extended into 3D in coursework 2.
The game scenario consists of a spacecraft in the centre of the
screen.
The ‘asteroids’ appear at the start of the game and the
spacecraft can turn
freely about its axis by and fire missiles at the asteroids. The
asteroids
themselves do not translate but rotate slowly about their axis.
If a missile fired from the ship strikes an asteroid, the asteroid
disappears and
the score is increased by 10 points. Once all the asteroids have
been hit then
new set of asteroids should be redrawn randomly1 on the screen
but not
drawn in the position where the ship is. The number and shape
of the
asteroids is up to you. The game goes on indefinitely but feel
free to put in a
pause or stop.
The star field behind the main scene should drift slowly2 from

8. top to bottom or
left to right. With new stars appearing as the old stars
disappear.

9. 1
Note:
Pre-­‐determined
positions
(at
least
3
different
positions
for

10. each
asteroid
is
also
acceptable).
Random
generation
will
score
5%
more
in
this
section.

Static
(non
moving)

Figure 1 Screen Mock up (asteroids can be filled
(GL_POYGON) or line
drawn (GL_LINES))
Technical
Details
The screen consists of several objects:
a) Rotating spaceship (controlled by left/right arrow keys)
b) Asteroids (Hexagons are shown here but can be any shape
you
choose)
c) Moving star field
d) The missiles from ship
e) The score panel

12. Notes: All the shapes in the figure are built from simple
primitives and you are
free to copy this design without penalty or you can create your
own shapes.
The stars should be drawn by using points (GL_POINT), note
that you
can change the size of a point with an OpenGL command.

Note you use blended colours to give the impression of texture
on the
asteroids and ship. In coursework 2 we will use lighting to
achieve this
effect but for this coursework use different colour vertices.
Deliverable for coursework one:
1. Spacecraft rotation code – model and rotation code (5% for
model and 20% for rotation code and user controls) 25%
2. Moving star field (10% only if static) – 20%
3. Spinning asteroid model– 10%
4. Asteroid random or predetermined redraw code – 20%

13. 5. Working Score panel – 15%
6. Collision detection – 10%
(Included in these are marks for coding standard and code
quality)
Important Notes:
Make sure you attempt all of the above I am not looking for
2D/3D
art skills so don’t be too concerned with aesthetics at the
moment.
Create C/C++ functions that are sensibly named such as
drawSpaceShip(…) drawAsteroids(…) asteroidHit(…)
rotateShip()
etc.
Note even if you achieve a requirement you may not get full
marks
if it is perceived by the marker that a better solution was
possible.
All work is marked in a viva and the marker’s academic
judgment
is final should not be questioned.
Feel free to include any drawings (concept art and sketches) you
have done.
Please comment your code extensively and put the author of any
code that is not your own in the comments above the code
section.
Note you will lose marks for uncommented code.

14. Please submit your code via Blackboard by 10AM on the due
date
by zipping your Visual Studio project.
