Program 1
(Total: 100 pts)
Write a Java programwhich uses the LWJGL library to draw a window of 640×480 in the center of the screen.
Your program should then read in coordinates from a file titled coordinates.txt and draw the primitives in the
same window using the algorithms for each primitive as discussed in class. The program should draw the
primitives in different colors (red for lines, blue for circles and green for ellipses) on a black background.Use
the glVertex2f() command to plot the primitives pixel by pixel. Finally, your program should also use the
input.Keyboard class to have the escape key quit your application.
If you are motivated enough, you may also add extra functional keys that would allow the user to change the
colors of the primitives. These added functions should be clearly stated in your comments.
The given coordinates.txt file will be in the following format:
l -15,-15 150,180
c 100,150 80
e 225,370 35,75
l -100,100 50,75
e 200,-100 50,50
l stands for a line and is followed by a space, this is then followed by the two endpoints of the line separated by
a space. c stands for a circle followed by a space, the center of the circle, space and then the radius of the circle.
e stands for ellipse followed by a space, center of the ellipse, space again followed by value of rx and
ry(separated by a comma).
When your program is evaluated, a different coordinates.txt file will be used by me– so be sure your algorithm
tests all cases for each of the three primitives.
Note: Please do not turn in anything that does not use Java with our LWJGL library. Your programs should be
hand-coded. Hence, don’t use pre-existing code from other texts or from the internet.
What to turn in:
– Soft copy of the program (using Blackboard)
