## Preview

In this module, I will present and explain four programs that use the game-math library named GM2D04 . The purpose of the first program named VectorAdd05 is to use the addVectorToPoint method of the GM2D04.Point class to translate a geometric object from one location in space to a different location in space.

The purpose of the program named VectorAdd05a is to accomplish the same translation operation, but in a possibly more efficientmanner.

The purpose of the program named VectorAdd06 is to teach you how to do rudimentary animation using the game-math library.

The purpose of the program named StringArt01 is to teach you how to use methods of the game-math library to produce relatively complexdrawings.

All of the programs are interactive in that they provide a GUI that allows the user to modify certain aspects of the behavior of the program.

I will also provide an exercise for you to complete on your own at the end of the module. The exercise will concentrate on the material that you have learnedin this module and previous modules.

## The game-math library named GM2D04

The game-math library that we are developing in this collection of modules has undergone several updates since its inception in the first module. The versionof the library that existed at the end of the previous module was named GM2D04 . No revisions have been made to the library since that module and we won't be makingany revisions during this module.

The source code for the library named GM2D04 is provided for your convenience in Listing 17 near the end of the module. Documentation for the library was provided in the earlier module titled GAME 2302-0125: Vector Addition .

The main purpose of this program is to use the addVectorToPoint method of the GM2D04.Point class in the game-math library to translate a geometric object from one location in space to a different location in space.This is illustrated in Figure 1 , which shows one hexagon (shown in black) having been translated by 50 units in both the x and y directions and coloredred at the new location.

Figure 1 Translation of black hexagon to location of red hexagon.

Various other game-math library methods are also used

Along the way, the program uses various other methods of the classes in the game-math library named GM2D04 to accomplish its purpose.

The program initially constructs and draws a black hexagon centered on the origin as shown in Figure 1 . The six points that define the vertices of the hexagon lie on a circle with a radius of 50 units. The points at the verticesand the lines that connect the points are drawn. In addition, the program causes the hexagon to be translated by 50 units in the positive X direction and 50units in the positive Y direction. The translated hexagon is drawn in red. The original black hexagon is not erased when the translated version is drawn in red.

A graphical user interface (GUI)

A GUI is provided that allows the user to specify the following items and click a Replot button to cause the drawing to change:

how can chip be made from sand
is this allso about nanoscale material
Almas
are nano particles real
yeah
Joseph
Hello, if I study Physics teacher in bachelor, can I study Nanotechnology in master?
no can't
Lohitha
where is the latest information on a no technology how can I find it
William
currently
William
where we get a research paper on Nano chemistry....?
nanopartical of organic/inorganic / physical chemistry , pdf / thesis / review
Ali
what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level
learn
da
no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts
Bhagvanji
hey

da
Application of nanotechnology in medicine
has a lot of application modern world
Kamaluddeen
yes
narayan
what is variations in raman spectra for nanomaterials
ya I also want to know the raman spectra
Bhagvanji
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think
Professor
Nasa has use it in the 60's, copper as water purification in the moon travel.
Alexandre
nanocopper obvius

what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
How we are making nano material?
what is a peer
What is meant by 'nano scale'?
What is STMs full form?
LITNING
scanning tunneling microscope
Sahil
how nano science is used for hydrophobicity
Santosh
Do u think that Graphene and Fullrene fiber can be used to make Air Plane body structure the lightest and strongest. Rafiq
Rafiq
what is differents between GO and RGO?
Mahi
what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION
Anam
analytical skills graphene is prepared to kill any type viruses .
Anam
Any one who tell me about Preparation and application of Nanomaterial for drug Delivery
Hafiz
what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
