CAP4730: Assignment 1

Getting up to speed with C/C++ and OpenGL

---

Assigned: Monday, January 9th, 2006
Due: Monday, January 30th, 2006

• Get a "skeleton" program to compile and execute on your platform of choice. 
• Use OpenGL to draw discs and move them about.

From the class webpage, download assignment1.zip. Make a directory and move assignment1.zip into it.  It should unzip into the appropriate directories, along with any needed .lib files.

What is given to you:

project1.cpp - a skeleton OpenGL/GLUT program that can be thought of as a framework for your work.  It provides a rendering window, framebuffer, and callbacks for keyboard and mouse actions.
project1.h - header file that containts data structures for main.cpp
glut.h, glut32.lib, glut32.dll - Windows library that needs to be linked in (for UNIX guys, link in -lglut)
project1.dsw - project's Visual C++ 6.0/.net workspace. 

• Compile assignment #1 and make sure it works
• It should draw one disc in the center of the screen

To do:

• Draw a rectangle
• Have the disc move about within the rectangle and bouncing off the sides of the rectangle.
• The user should control the sides of the rectangle with the following:
• ‘a’ and ‘s’ moves the left side of the rectangle left and right, respectively
• ‘d’ and ‘f’ moves the right side of the rectangle left and right, respectively
• ‘q’ and ‘z’ moves the top side of the rectangle up and down, respectively
• ‘w’ and ‘x’ moves the bottom side of the rectangle up and down, respectively
• Don’t worry about handling special cases such as if the top and bottom switch sides, etc.
• The disc should bounce off the sides of the rectangle appropriately.
• The user can double the number of discs with the ‘+’ and cut the number of discs in half with the ‘-‘. Your program should handle drawing at least 8192 discs.
• Calculate and display (in the upper left-hand corner) in real-time your program's frame rate (up to tenths of a frame, e.g. 27.5 fps).

Quality (Choose 1. Here are some EXAMPLES. You can CHOOSE TO DO YOUR OWN):

• Make a game
• Allow for screenshots
• Put in a particle system
• Inter-disc collisions

Report (1 page):

• Write 1 paragraph on what you implemented, and 1 paragraph on how you moved the discs about.
• Answer the following questions with at most 2 sentences each:
• 1a. What factors impact program speed?
• 1b. How many discs does it take for your machine to run at 5 fps?
• 2. Create a graph of your program's performance (x axis - number of discs, y axis - frame rate)

Turn in:

· makefile, .sln/project, .cpp, .h – what we need to compile your project.  If you think any additions you might have made would cause problems, please verify w/ your TA.

· .doc or .pdf of your report

· Please head to www.cise.ufl.edu/~lok/teaching/csgss06/turnin.html for the latest info

Grading:
100 pts (15% of total grade)
If you get it right: 70 points

· 30 points - disc movement

· 20 points - keyboard input

· 10 points - fps

· 10 points - disc increase/decrease

Quality: 20 points

Documentation: 10 points
