b$)$ Hidden Surface Elimination concept: Complete Problem $6\mathrm{.}9($page $223)$ of the

textbook. Write a java program to generate the $3$D data file for the steps shown

in Fig. $6\mathrm{.}21.$ The program should take in command$-$line arguments for the

number of steps $\text{'}$ n $\text{'}$ and step dimensions $($length of each step $\text{'}$ a $\text{'},$ angle between

two successive steps in degrees 'alpha'$).$

In other words, after compiling your program, you may run it by typing the

following as an example:

java Beams $420$ steps.dat

where n$=4,$a$=2,$ alpha $=0,$ and steps. dat is the generated output data file.

The generated output data file can be viewed by running Painter.java or

ZBuf.java in Chapter $6$ and then loading the data file. A sample data file

"steps.dat" may be downloaded from eLearning for you to view it in action. The

work will be evaluated on the following test cases

n$=4,$a$=2,$ alpha $=0$

n$=10,$a$=4,$ alpha $=18$

n$=30,$a$=2,$alpha$=12$

Fig. $6\mathrm{.}21$ Steps

$6\mathrm{.}9.$ Write a $3$D data file $($using a text editor$)$ for the steps shown in Fig. $6\mathrm{.}21.$ Apply

the programs Painter.java and ZBuf.java to it$.$ Can you write a program to

generate such data files? In such a program, the number of steps and the

dimensions should preferably be variable.

Can you help me please
