The programming assignments for this course will use OpenGL graphics library. Using such a tool relieves us of having to deal with the hardware directly. It also implements standard graphics facilities. For most of the assignments, some facilities of OpenGL will be "off-limits" so that you can learn through doing some of the basic graphics processing which is normally handled for you behind the scenes.
OpenGL itelf does not provide commands for performing windowing tasks or for obtaining user input. These commands are provided by GLUT (the OpenGL Utility Toolkit). GLUT provides commands to create windows, subwindows, and menus; and to handle input from a variety of devices via a callback mechanism.
The program starts up a graphics window with a triangle in it. To exit, enter a "q" in the graphics window. I have added double buffering, mouse handling (you click on the left mouse button and drag to move the triangle around), and a menu example (right click to change the color of the triangle).
Note that program is not very sophisticated--it is only meant to help get you started. In order to handle a more complex collection of tasks, it is advisable to give careful thought to your design. Also, a real program would check that the first mouse click was inside the triangle.
The program compiles on machines gr01-gr08 lab machines with:
cc triangle.c -o triangle -lGL -lGLU -lglut -lm
In this course we will be requiring a makefile with every programming assignment which builds your program. Here is an example makefile for the triangle program for Linux (Fedora core 3) as installed on most CS student labs and grad student offices.
This program has example code shows one way (not necessarily the best way) how to coerce OpenGl to multiply matrices for you, AND the same matrix multiplication using the UA computer vision library (kjb library). To make the demo work you need the includes and library load path in the makefile as in this one. . Further information about the vision library can be found by adding /home/kobus/doc to your MANPATH and doing a "man kjb". The following example from the vision course may help. To compile it, use this compile line .
This program ( makefile ) has example code that shows how OpenGL precision problems can cause anomolies. If you give OpenGL integer vertices, they get converted to floating point, and then further computations occur, each subject to precision problems. Thus it seems that if it is critcal where a point ends up, then it is better to send in a floating point number which has 0.5 added to it, as the mapping to screen will eventually occur with a truncation.
Some (aging) documentation is available in pdf or postscript form.
Use "man". As far as I can tell, man on the graphics lab machines have no trouble finding the OpenGL pages, but if you run into touble, you could try adding /usr/X11R6/man:/usr/share/man to your MANPATH environment variable.
For GLUT, there is an intro page ("man glut"). If you like to guess which man pages might be useful, here is the results of "/bin/ls -1 glut*" in dicrectory /usr/share/man/man3 and "/bin/ls -1 gl*" in directory /usr/X11R6/man/man3" on one of the graphics machines. Ingore the dot and everything after it. For example, the second glut entry below is a hint that "man glutAddMenuEntry" might be fruitful.
