[CMSC 437] | [Syllabus] | [Lecture Notes] | [Homework] | [Projects] | [Files] | [Notes, all]
The most important item on all homework is YOUR NAME!
Print. No readable name, no credit.
Staple or clip pages together.
Homework must be submitted when due. You loose 10%, one grade,
the first day homework is late. Then 10% each week thereafter.
Max 50% off. A zero really hurts your average!
Paper or EMail to squire@umbc.edu ONLY PLAIN TEXT.
I can NOT accept OCTET/STREAM. .doc .gif .jpg .rtf ...
If I can not read or understand your homework, you do
not get credit. Type or print if your handwriting is bad.
Homework is always due on a scheduled class day within 15 minutes
after the start of the class. If class is canceled then homework
is due the next time the class meets. EMailed homework has until
midnight the day it is due.
EMail only plain text! No word processor formats.
You may use a word processor or other software tools and
print the results and turn in paper.
Put CS437 and HW number in subject line.
The "submit" facility only works on the "gl" machines.
The student commands are:
submit cs437 hw1 some_file
submitrm cs437 hw1
submitls cs437 hw1
This is to be sure you have a chance to pass the course:
On some Microsoft windows system, yours or UMBC,
a) compile and execute w1gl.c a basic OpenGL program
b) compile and execute W1frame.java a basic Java program
On some Linux (or in general Unix) system, yours or UMBC,
d) compile and execute w1gl.c a basic OpenGL program
e) compile and execute W1frame.java a basic Java program
f) compile and execute w1.c a basic X windows program
Turn in the command you used to do any two (2) of the above.
(It is OK, but not necessary, to say what setup you did.)
Get detailed help from GUI help on Windows and Linux
The source code and libraries are available in many places,
e.g. WEB download
CD in class textbook for GLUT, OpenGL Utility Toolkit.
a CD may be passed out in class
If you could not do any of the five by the second class,
you should consider dropping the course. It is OK if it took
you four to eight hours to get the basic process working.
Results are what is important.
Combine the concepts of Lecture 5 Menu and Lecture 6 Input Text to have a program read text in the graphics window, that text being a file name (of your programs source code) and reading and printing at least one line of the file in the graphics window. Typically, but not required, there would be a "File" menu and an item on this menu would be "Open" that asked for a file name. The area for inputting the file name may be fixed or can popup. This may be a small stand alone program in any language on any platforms. EMail or 'submit' your source code and demonstrate in class. (I do not have all possible environments to run your code.) or This may be embedded in your project application, assuming you started or are about to start your project.
See Lecture 9
In the language of your choice, on the platform of your choice, show the code that provides for the user to select some item in the GUI. Graphical item selection, not menu selection. This can be a small stand alone program -or- your project as it is now providing the ability to select an item is working. You may, yet do not have to, do anything with the selected item. (Well, you should somehow clue the user about which item was selected. e.g. pick2.c rubber2gl.c Rubber2.java Select.java Select2.java)
In the language of your choice, on the platform of your choice, write the code that displays at least two fonts in the GUI. The fonts may be, yet do not have to be, user selectable. This can be a small stand alone program -or- your project as it is now providing the ability to display a font is working.
See Lecture 19
In the language of your choice, on the platform of your choice, write the code that displays a clock in the GUI. The clock can be analog or digital. The analog clock must have a second hand that moves reasonable accurately, the minute and hour hand are optional. The numbers from 1 to 12 are optional, the motion is the point of this homework. The digital clock must display at least hh:mm:ss and the seconds must be reasonably accurate. Yes, this is as simple as getting the date and time string and just writing it to the GUI display like any other text. This can be a small stand alone program -or- your project as it is now providing the ability to display time is working. The demonstration program for getting time in "C" is: time_of_day.c with sample output: 0 CPU time 10 / 8 / 104 23 : 57 : 16 ascii string Tue Aug 10 23:57:16 2004 waste time 0.035529 0.31 CPU time For X Windows Motif analog clock, the classic program is xclock.c , yet, it is designed to update once a minute and needs a second hand. For Java, date and time is obtained in the sample program: time_of_day.java with sample output: time_of_day from Java java.util.GregorianCalendar[time=1092208960278,areFieldsSet=true, areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id= "America/New_York",offset=-18000000,dstSavings=3600000,useDaylight=true, transitions=235,lastRule=java.util.SimpleTimeZone[id=America/New_York,offset =-18000000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=3, startMonth=3,startDay=1,startDayOfWeek=1,startTime=7200000,startTimeMode=0, endMode=2,endMonth=9,endDay=-1,endDayOfWeek=1,endTime=7200000,endTimeMode=0]], firstDayOfWeek=1,minimalDaysInFirstWeek=1,ERA=1,YEAR=2004,MONTH=7, WEEK_OF_YEAR=33,WEEK_OF_MONTH=2,DAY_OF_MONTH=11,DAY_OF_YEAR=224, DAY_OF_WEEK=4,DAY_OF_WEEK_IN_MONTH=2,AM_PM=0,HOUR=3,HOUR_OF_DAY=3, MINUTE=22,SECOND=40,MILLISECOND=278,ZONE_OFFSET=-18000000,DST_OFFSET=3600000] 7/11/2004 3:22:40 278 milliseconds t1=1.092208960278E12 t2=1.092208960325E12 t2-t1=47.0 milliseconds
In the language of your choice, on the platform of your choice, write the code that displays a "Splash" for three (3) seconds in the GUI. e.g. What some games do when you win or loose. This can be automatic or in response to a user action. (Use the information from samples in HW5 to get time.) This can be a small stand alone program -or- your project as it is now providing that the ability to display an event for a fixed time, is working.
