COMP4033 Assignment 1 - Basic Computer Graphics (5%)

Due: 11:59pm, 13 March 2021

Complete the following two exercises by writing a Java program for each:

1. Draw a set of concentric pairs of squares, each consisting of a square with horizontal and vertical edges

and one rotated through 45°. Except for the outermost square, the vertices of each square are the

midpoints of the edges of its immediately surrounding square, as Figure 1 shows. It is required that all

lines are exactly straight, and that vertices of smaller squares lie exactly on the edges of larger ones.

2. Write a program that draws a pattern of hexagons, as shown in Figure 2. The vertices of a (regular)

hexagon lie on its so-called circumscribed circle. The user must be able to specify the radius of this circle

by clicking a point near the upper-left corner of the drawing rectangle. Then the distance between that

point and that corner is to be used as the radius of the circle just mentioned. There must be as many

hexagons of the specified size as possible and the margins on the left and the right must be equal. The

same applies to the upper and lower margins, as Figure 2 shows.

Note: you should try to minimize the number of lines that are drawn more than once. You can see the

repeated lines by using a different foreground color for each round of drawing, or better, by using the

XOR writing mode with the foreground color being black (if you know how to use XOR mode).

Put the 2 Java source programs in a ZIP file and name it as “Ass1_1234567890" (replace

1234567890 with your student ID number). Submit your ZIP file through iSpace before the due

time. Late submissions will NOT be accepted.
