## Preface

This module contains review questions and answers keyed to the module titled GAME 2302-0110: Updating the Game Math Library for Graphics .

The questions and the answers are connected by hyperlinks to make it easy for you to navigate from the question to the answer and back again.

## Question 1.

A point is simply a location in space. It has no width, depth, or height. Therefore, it cannot be seen by the human eye, which means that we can't draw apoint on the computer screen. However, it is possible to draw an object on the computer screen that indicates the location of the point.

True or False?

## Question 2

A point in space exists only after a visual object is created to mark the location of the point.

## Question 3

A point is a small black circle.

True or False?

## Question 4

Kjell tells us that a line segment is the straight path between two points, and that it has no thickness. Since it has no thickness, a line cannot be seenby the human eye.

True or False?

## Question 5

GM2D02.Point objects represent themselves as small black squares in a graphics context for the benefit of human observers.

True or False?

## Question 6

GM2D02.Vector objects represent themselves as lines with arrow-heads at their heads in a graphics context for the benefit of human observers.

True or False?

## Question 7

A GM2D02.Vector object is:

• A. An underlying data object
• B. A graphics object
• C. Both of the above
• D. None of the above

## Question 8

All Java parameters are passed to methods by reference.

True or False?

## Question 9

Java supports both primitive variables and reference variables.

True or False?

## Question 10

The GM2D02 library is an update of the earlier game-math library named GM2D01 . This update added the following new capabilities:

• A. Draw circles to represent GM2D02.Point objects.
• B. Draw visible lines to represent GM2D02.Line objects.
• C. Draw visible lines and circles to represent GM2D02.Vector objects.
• D. Call a setData method to change the values in a GM2D02.ColMatrix object.
• E. Call a setData method to change the values in a GM2D02.Point object.
• F. Call a setData method to change the values in a GM2D02.Vector object.
• G. Call a setHead method or a setTail method to change one of the points that defines a GM2D02.Line object.
• H. All of the above
• I. None of the above

## Question 11

The updated constructors in the GM2D02 library create and save clones of the ColMatrix and/or Point objects originally used to define the Point , Vector , and/or Line objects.

True or False?

## Question 12

The createImage method belonging to a JFrame object can be used to create an off-screen image.

True or False?

## Question 13

If the contents of an off-screen image are displayed on the screen, the units of width and height are measured in pixels.

where we get a research paper on Nano chemistry....?
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
Preparation and Applications of Nanomaterial for Drug Delivery
revolt
da
Application of nanotechnology in medicine
what is variations in raman spectra for nanomaterials
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
Alexandre
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
Damian
Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
