Coursework

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

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

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

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%
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.

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