1: Explain the application of a computer graphics
There are several uses of CG which are very useful in the current scenario. Some of its uses include,
A).Computer program Development B).Making movies C).Video Games D).Catalogs designing E).Creating Commercial Arts F).Scientific Modelling
A). Video Games : These games requires human interaction with the User Interface for making nice visual result on the Video Device
B).Education Field:
In the learning process, acquiring knowledge and skills required for better career path CG is needed. So Computer generated models in economic, financial and physical systems are often used.
C). Computer Aided Design (CAD):
Most of engineering and Architecture students are concerned with Design. CAD is used to design various structures such as Computers, Aircrafts, Building, in almost all kinds of Industries (where designing is necessary)
D). Computer Arts:
If we are intelligent enough we can rock by making creative arts using these Graphics tools. For making these arts we generally use CAD packages, paint and Paint brush programs and in animation too
Computer Arts Examples include Logo design (for companies, college, Industries, Institutions), Cartoon drawing, Product advertisements and many
E). Simulation:
Using CG graphics reproduction or duplicating already existing thing will be done. For Instance, if we go for the Flight simulators, these computer generated images are very much needed for training pilots to understand easily (learning standard methods)
F) .Entertainment :
CG are mostly used in music videos, motion pictures, and cartoon animation films. For finding out tricks to be used in Games, for its interactivity we often use CG
G). Image Processing: (Medical)
In Medical field, concerning Image Processing CG is used to various technologies to interpret already existing pictures and is useful to modify Photographs and TV scans. Basically CG is used to improve the picture quality, and visualizing effects. Some of its applications include,
I). Tomography
ii).Ultrasonic medical scanners
iii).Picture enhancements
H). User Interfaces (Graphical User Interfaces)
CG is effectively used to make Menus, Icons (Graphical Symbols),to make window manager (multiple windows).And Some of the Graphic packages includes PHIGS,Graphics Kernel System,Painting,drawing.
2: Differentiate between interactive and non-interactive graphics
Interactive
Interactive Computer Graphics involves a two way communication between computer and user. Here the observer is given some control over the image by providing him with an input device
for example the video game controller of the ping pong game.
Non-interactive graphics
It is the computer graphics in which user does not have any kind of control over the image.
Image is merely the product of static stored program and will work according to the instructions given in the program linearly. The image is totally under the control of program instructions not under the user. Example: screen savers.
3: Give the benefits and shortcomings of interactive and non-interactive graphics
Benefits interactive graphics
a. (^) A better information recognition process
b. It is possible to offer a higher information density
c. We can show object relationships (interactivity)
d. Color can be used
e. Greater productivity (efficiency, use costs)
Benefits of non-interactive graphics.
Creates realistic images. The computer aids the user on how to create and manage images.
