## 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.

who was the first nanotechnologist
k
Veysel
technologist's thinker father is Richard Feynman but the literature first user scientist Nario Tagunichi.
Veysel
Norio Taniguchi
puvananathan
Interesting
Andr
I need help
Richard
anyone have book of Abdel Salam Hamdy Makhlouf book in pdf Fundamentals of Nanoparticles: Classifications, Synthesis
what happen with The nano material on The deep space.?
It could change the whole space science.
puvananathan
the characteristics of nano materials can be studied by solving which equation?
sibaram
synthesis of nano materials by chemical reaction taking place in aqueous solvents under high temperature and pressure is call?
sibaram
hydrothermal synthesis
ISHFAQ
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
Giriraj
Preparation and Applications of Nanomaterial for Drug Delivery
revolt
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
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
STM - Scanning Tunneling Microscope.
puvananathan
how did you get the value of 2000N.What calculations are needed to arrive at it
