COMP2004 Computer Graphics Assignment
“Rescue Mission” using OpenGL Theme : Save Sven from Water Sheep
1. INTRODUCTION
First of all, if the assignment theme does not make any sense to you, do not worry about it. Basically, I would like you to create a simple game where you have to rescue your wolf pet named “Sven” from the mastermind villain named “Water Sheep”.

It is not necessary to design Sven and Water Sheep exactly like the pictures above, those are for your references. If you are curious about the origin of their names, feel free to search it in the Google.

The narrative looks like this:
You will create a simple game arena such as abandoned ruins, spooky forest, forgotten
tomb, villain headquarter, etc.
The main character in the game is represented as the camera (first person view). If the
main character is holding an object, it should be visible on the viewport.
The arena will be darkish (not completely pitch black) and you only have one light source which you can pick up and bring with you such as torch or lantern which will
illuminate the area around you.
Sven is injured and sitting somewhere in the game arena. The objective of the game is to pick him up and bring him to the exit/safe zone.
When you pick Sven up, Water Sheep will get angry and trying to chase the
player down (basically coming towards the camera). Water Sheep will also release his minions OR activate traps to prevent you from escaping. I will leave this to your imagination. Some examples include: releasing zombies, spiders, and skeleton to chase you down. The traps might include trap hole, fire trap, spike trap, descending ceiling, etc.
The player will be defeated if he is hit once by the Water Sheep or his minions or by the traps. When you are defeated, the camera position should appear laying down on the ground (unable to move anymore) and show the prompt “press
If the player manage to reach the exit/safe zone with Sven , he wins the game.

2. REQUIREMENTS
In this assignment, you can unleash your imaginations and use OpenGL with C/C++ programming to produce a scene(s) that represents what you envision to be associated with the theme. These are the general requirements of the assignment:
This assignment is focused on the technical skills on OpenGL programming. Artistic creativity is still encouraged, but not required. Please spend most of your effort learning OpenGL itself.
Interactivity exists in OpenGL assignment. For example, you can explore the world by ‘walking around’ with , ,
Sven up, and many more.
It is possible to have multiple light sources in OpenGL. For simplicity, you only need
to have one light source. However, the effect of ambient, diffuse, and specular has to
be clearly visible.
In order to make it more fun and testing your creativity, the only shape you can use for
this assignment is “box” shape. Yes, you read that right, ONLY “box” shape. NO sphere, cylinder, cone, pyramid, torus, and any other polyhedron. You can apply any affine transformation to it (enlargement, shrinking, stretching, rotation, even shearing) and combine with other boxes to create anything. You can think it as if you are playing toy block (but only box). If you are familiar with video games, it is similar to Minecraft (https://minecraft.net/en-us/). You create the game only with boxes.
Program Requirements:
1. At least 6 composite objects and 6 different image textures. Since you can only use boxes, be creative on combining these boxes to create complex objects (e.g. table on tutorial
Sample_1). Sven and Water Sheep should be among these 6 objects. Please do
not just create a simple white box and call it Sven . At least, make it look reasonable
with legs and head.
2. Only one light source is required. You can create something like a simple
lantern/candle/torch as the light source. You should be able to carry this light with you. Pressing key
3. Implementing a simple light source attenuation (lecture 7). As the distance to the light source is increasing, the brightness should be reduced gradually. Pressing the key
4. The effect of the light source should be reasonable. For example, metal surface and waxed apple should be shiny, while wooden plate should be dull.
5. As you have noticed from the examples, you can only move forward, backward, left, and right with , , and

projection.
8. At least 2 animations should present in your created scenery. One should start playing
the moment the program start rendering, while the other one only plays when you pick
Sven up (by pressing
9. Pressing the key
in the game back to the original position.
10. Since this is a darkish environment, it might be a bit too dark for me to assess everything.
So, please implement a functionality to toggle between the “darkish scenery” and “everything bright scenery” with the key
11. You need to implement a simple “hitbox” to trigger some events such as hit by the
zombies or being close enough to Sven to pick him up. One of the simplest way to do this is by utilizing the distance from the camera to the object of interest. When the distance is lower than a threshold, it can be regarded as “collision”. Please observe Sample_1 in the tutorial to see how this idea is applied to press the red button.
12. The difficulty level of the game is up to your decision. You can make it extremely easy or extremely difficult to beat, as long as we can assess it properly.
The final version of your program must work on the lab workstations and be presented and assessed in the Lab. No technical support will be provided for your work on your own PC. Please ensure that clear reference is given if you do have to use some external codes and resources.

3. SUBMISSION
This assignment is due on the 28th October 2019, Monday at 9:00am. You must submit
two files:
A short report of up to 5 pages in PDF format. In the report, you must list the implemented functions and briefly explain the main algorithms you used for modelling, rendering and animation. Please provide specific description on YOUR OWN work, not just a list of what are required. Please describe any simple or composite objects you use to model YOUR OWN objects, and what kind of surface finishing you have employed for each of them. If you use any external tool to create a complicated object or finishing, please provide a brief description and the usage of the tool. You are also required to describe the animation you have produced by providing the design ideas and their implementations. The report will contribute to 20% of the assignment marking.
A compressed zip file containing:
The whole folder containing your source code directories, texture images, and relevant libraries;
A simple readme.txt which briefly describes each source file and the way to compile and run your code(s) (should be similar to compiling your tutorial codes);
The completed and signed Declaration of Originality. By submitting the sheet, you declare that the work submitted are solely your own work.
Both of these files should be uploaded to the Blackboard (AssessmentOpenGL Assignment Submission 2019) before the deadline. Please make sure the completeness and correctness of your files before your submission. All late submissions will not be accepted. No hard copy submission is required.
In addition, you should leave a copy of the above files (not zipped) and the executable file in your main directory under /CG/assignment/. Please note that the time-stamp for the source files / executable file must be before the deadline.
During the practical sessions in Teaching Week 12 (Starting on 28th October 2019), you must first show the time stamp of your executable file to your tutor. You must demonstrate and be ready to answer any question relating to your program. You will be asked to make slight changes to the program to clarify your understanding of OpenGL graphics programming or to prove your authorship if any doubt arise. Failing to turn up at the demonstration in your own enrolled practical session will result in a ZERO for the assignment, and may result in a F-IN for the whole unit.
