You will submit homework source code and output on GL after 9/27/2021. Homework grade is recorded based on submission. / not online/ Homework must be submitted when due. You loose 10%, one grade, the first day homework is late. Then 10% each class thereafter. Max 50% off.
This homework is to be sure you have a chance to pass the course: You get to choose the operating system, programming language and graphics library for your homework and project. The purpose of the homework is to demonstrate GUI tasks that may be used in your project. You need to do any three of the following: You may do more. 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 c1) compile and execute w1wx.py a basic Python2 program or c2) compile and execute w1wx.py3 a basic Python3 program and c3) compile and execute w2wx.py3 a basic Python3 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 w1tk.py3 or w1qt.py a basic Python program f1) compile and execute w2tk.py3 a mouse test Python program g) compile and execute w1.c a basic X windows program On a Mac or any platform, phone, pad, in any language, h) compile and execute a program that brings up a window, draws lines (not using forms) and draws text in the same window as the lines. Make it similar to any w1* . i) compile and execute an equivalent program to w1* in some other language with a graphics library. j) install and run JavaScript in a HTML5 w1.html file and view it in your browser Submit file with your name and name of operating system and the command you used to do any three (3) of a) through j) (It is OK, but not necessary, to say what setup you did.) Run the three programs for the instructor in class. (On your laptop or lab computer.) Get detailed help from GUI help on Windows and Linux The source code and libraries are available in many places, e.g. WEB download If you could not do any of the ten a) through j) 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 so that you will be able to do your project.
Combine the concepts of Lecture 5 Menu and Lecture 6 Input Text. Write and demonstrate a program that has the user enter a file name into your graphics window and then read that file and display the file in a 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. For your benefit it should be the same language and graphics you are planning to use in your project. Remember, it has to be a server side file in JavaScript or a local file on phone or pad. Just submit source code and at least one image. submit cs437 hw2 your_files

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. The selection may change the color or provide some other feedback to the user, showing what was selected.. This can be a small stand alone program or the beginning of your project that is now providing the ability to select an item. 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.) The selection may change the color or provide some other feedback to the user, showing what was selected. e.g. pick2.c rubber2gl.c Rubber2.java Select.java Select2.java) submit cs437 hw3 your_source and at least one image
In the language of your choice, on the platform of your choice, write the code that displays at least two fonts in the GUI. Each font should be in two sizes. eg 12 and 24, your choice. The fonts may be, yet do not have to be, user selectable. Or, do a real 3D program for use with or without glasses. This can be a small stand alone program or the beginning of your project that is now providing the ability to display more than one font.. submit cs437 hw4 your_source and at least one image

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 the beginning of your project that is now providing the ability to display time. 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 Python3 demo of time and date now.py3 source code now_py3.out output time and date 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 Sample code to get time and output at 5 second intervals: (You must display one in a graphics window for homework.) time_test.c time_test.java time_test.py time_test.f90 submit cs437 hw5 your_source and at lease one image
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. You have something on the screen that the user can see. Three seconds later you add something to the screen, not deleting what is already there. e.g. What some games do when you win or loose. This may start automatically or in response to a user action. Or, do something with motion that uses timing to control the speed, and stops after some reasonable, pre programmed time. (Use the information from samples in HW5 to get time.) This can be a small stand alone program or the beginning of your project that is now providing the ability to display an event for a fixed time. submit cs437 hw6 your_source and at least one image
