CISC/CMPE 454 Computer Graphics - Assignment 1 - Asteroids
CISC/CMPE 454 Assignment 1 - Asteroids
Due Friday, January 27 at noon
You will implement parts of the Asteroids game by extending the skeleton code provided in this directory. You may work individually or in groups of two. Graduate students must work individually.
Compile the code
On Linux:
Go to the linux directory. Execute make
If this fails, you may need to install the glfw library like this:
sudo apt-get install libglfw3-devOn Windows with Visual Studio:
Click on a1.vcxproj Press F7.
On Mac:
Go to the macos directory. Execute make
If this fails, you may need to install gcc and glfw by following the instructions in the README.txt file in the macos directory.
Run the code
Run the code and verify that a window pops up with the Asteroids world. On Linux and MacOS this is done by typing ./asteroids in the terminal window.
Read the code
Read all of the code to get a general understanding of it. This should take several hours and will help a great deal later on.
Modify the code
All modifications are done in places with a comment saying "YOUR CODE HERE":
- Modify Object::modelToWorldTransform() to return the 4x4 transform that maps object points to the world coordinate system. An Object has a position, orientation, and a scale factor, all of which must be incorporated into the model-to-world transform. [1 mark]
- Modify Object::setupVAO() to set up the VAO that defines the object segments. [1 mark]
- Modify Object::draw() to draw the object in the correct position and orientation. You'll first need to find the model-to-view transform. [1 mark]
- Modify Ship::addThrust() to change the velocity. Use SHIP_THRUST_ACCEL, deltaT, and the current ship orientation. Modify Ship::rotateCW() to rotate the ship clockwise. [1 mark]
- Modify Segment::intersects() to determine whether two segments intersect. [1 mark]
- Modify Ship::fireShell() to set the initial state of a shell that is fired from the nose of the ship [1 mark]
- Modify World::updateState() to check for shell/asteroid collisions and to update the asteroids upon any such collisions. [3 marks]
- Optionally, implement additional features. Up to [3 bonus marks] can be awarded for additional features. You could have 3D asteroids (e.g. spinning) but still play on a flat plane. Or you could implement a flying saucer as in the original game. Or have a shield. Or have a number of lives that are shown on the screen and decremented.
Submit the code
Create a NEW DIRECTORY called 'a1'.
COPY ONLY THESE FILES into that directory:
.cpp .h README.txt
Do not include other files and directories. In particular, DO NOT INCLUDE THESE: .vs A1.txt a1.sln a1.vcxproj a1.vcxproj.filters glad include lib32 lib64 libglfw.so ll resource.h .
Your archive should be under 500 KB. If it's larger, you've likely included extra files, especially a Debug or .vs directory inside the windows directory.
Create a zip archive of that directory, named 'a1.zip'. If you use a different name, you WILL LOSE 1 MARK!
Submit the zip archive on OnQ.
