# 1.3 Game 2302-0110: updating the game math library for graphics  (Page 16/20)

Draw the border

While the single GM2D02.Line object is at each location, draw methods are called to cause a Line2D.Double object to be instantiated and rendered on each of the off-screen images. This results in four differentvisual manifestations of the single GM2D02.Line object, producing visible lines at the edges of each off-screen image. Although this code is notparticularly straightforward, the embedded comments should suffice to explain it.

Draw the hexagon

Essentially the same process is used to draw the hexagon shown in the left image in Figure 1 . You can view the code that does that in Listing 28 . Once you understand the code that I explained above, you should have nodifficulty understanding the code that draws the hexagon.

Draw the vectors

A very similar process is used to draw the vectors shown in the right image in Figure 1 . You can view the code in Listing 28 . Once again, if you understand the code that I explained above, you should have no difficultyunderstanding the code that draws the vectors.

That ends the explanation of the program named PointLine04 .

## Documentation for the GM2D02 library

Click here to download a zip file containing standard javadoc documentation for the library named GM2D02 . Extract the contents of the zip file into an empty folder and open the filenamed index.html in your browser to view the documentation.

Although the documentation doesn't provide much in the way of explanatory text (see Listing 26 and the explanations given above) , the documentation does provide a good overview of the organization and structure of the library. You may find ithelpful in that regard.

## Homework assignment

Your homework assignment for this module was to study Kjell's CHAPTER 0 -- Points and Lines plus CHAPTER 1 -- Vectors, Points, and Column Matrices down through the topic titled Variables as Elements .

The homework assignment for the next module is to study the Kjell tutorial through Chapter 2 -- Column and Row Matrix Addition .

In addition to studying the Kjell material, you should read at least the next two modules in this collection and bring your questions about that material tothe next classroom session.

Finally, you should have begun studying the physics material at the beginning of the semester and you should continue studying one physics module per weekthereafter. You should also feel free to bring your questions about that material to the classroom for discussion.

## Run the programs

I encourage you to copy the code from Listing 26 , Listing 27 , and Listing 28 , compile it, and execute it. Experiment with it, making changes, and observingthe results of your changes. Make certain that you can explain why your changes behave as they do.

## Summary

In this module, you learned how to update the game-math library to provide a number of new capabilities including the addition of graphics to the library andthe addition of set methods for column matrices, points, vectors, and lines.

You also saw sample programs that illustrate the use of those new capabilities and you learned how to draw on off-screen images.

Introduction about quantum dots in nanotechnology
what does nano mean?
nano basically means 10^(-9). nanometer is a unit to measure length.
Bharti
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
absolutely yes
Daniel
how to know photocatalytic properties of tio2 nanoparticles...what to do now
it is a goid question and i want to know the answer as well
Maciej
Abigail
for teaching engĺish at school how nano technology help us
Anassong
Do somebody tell me a best nano engineering book for beginners?
there is no specific books for beginners but there is book called principle of nanotechnology
NANO
what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
so some one know about replacing silicon atom with phosphorous in semiconductors device?
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Harper
Do you know which machine is used to that process?
s.
how to fabricate graphene ink ?
for screen printed electrodes ?
SUYASH
What is lattice structure?
of graphene you mean?
Ebrahim
or in general
Ebrahim
in general
s.
Graphene has a hexagonal structure
tahir
On having this app for quite a bit time, Haven't realised there's a chat room in it.
Cied
what is biological synthesis of nanoparticles
what's the easiest and fastest way to the synthesize AgNP?
China
Cied
types of nano material
I start with an easy one. carbon nanotubes woven into a long filament like a string
Porter
many many of nanotubes
Porter
what is the k.e before it land
Yasmin
what is the function of carbon nanotubes?
Cesar
I'm interested in nanotube
Uday
what is nanomaterials​ and their applications of sensors.
what is nano technology
what is system testing?
how did you get the value of 2000N.What calculations are needed to arrive at it
