Introduction to Computer Graphics Flashcards
computer graphics
is a branch of computer science that deals with generating images with the aid of computers.
computer graphics
is a core technology in today’s digital photography, film, video games, cell phone and computer display, and many specialized applications.
1960
when was the phrase “computer graphics” coined?
Verne Hudson, William Fetter
who coined the phrase “computer graphics” ?
Boeing
where was Hudson and Fetter working?
CGI
computer generated imagery
computer graphics
It is the use of computers to create and manipulate pictures on a display device. It comprises of software techniques to create, store, modify, represents pictures.
computer graphics
It is a production of images on computers for use in any medium.
bitmaps
way of turning a picture into a computer file made up of binary digits
bits
binary digits
raster graphics
a type of digital image that uses tiny rectangularpixels, or picture elements, arranged in a grid formation to represent an image.
Because the format can support a wide range of colours and depict subtle graduated tones, it is well suited for displaying continuous-tone images such as photographs or shaded drawings, along with other detailed images.
vector graphics
There’s an alternative method of computer graphics that gets around the problems of raster graphics. Instead of building up a picture out of pixels, you draw it a bit like a child would by using simple straight and curved lines calledvectorsor basic shapes (circles, curves, triangles, and so on) known asprimitives.
vectors
simple straight and curved lines
primitives
basic shapes (circle, curves, triangles)
3d graphics
The creation, display and manipulation of objects in the computer in three dimensions. 3D CAD and 3D graphics programs allow objects to be created on an X-Y-Z scale (width, height, depth).
xyz scale
width, height, depth
3d graphics
As 3D entities, they can be rotated and viewed from all angles as well as be scaled larger or smaller. They also allow lighting to be applied automatically in the rendering stage.
computer graphics
an art of drawing pictures, lines, charts, etc. using computers with the help of programming.
computer graphics
is made up of number of pixels. Pixel is the smallest graphical picture or unit represented on the computer screen.
interactive, non-interavtive
classification of computer graphics
interactive, non-interavtive
classification of computer graphics
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. This helps him to signal his request to the computer.
non-interactive
aka passive computer graphics. it is the computer graphics in which user does not have any kind of control over the image.
passive computer graphics
other name of non-interactive
computer art
application of computer graphics
Using computer graphics we can create fine and commercial art which include animation packages, paint packages. These packages provide facilities for designing object shapes and specifying object motion. Cartoon drawing, paintings, logo design can also be done.
computer aided drawing
application of computer graphics
Designing of buildings, automobile, aircraft is done with the help of computer aided drawing, this helps in providing minute details to the drawing and producing more accurate and sharp drawings with better specifications.
presentation graphics
application of computer graphics
For the preparation of reports or summarising the financial, statistical, mathematical, scientific, economic data for research reports, managerial reports, moreover creation of bar graphs, pie charts, time chart, can be done using the tools present in computer graphics.
entertainment
application of computer graphics
Computer graphics finds a major part of its utility in the movie industry and game industry. Used for creating motion pictures , music video, television shows, cartoon animation films. In the game industry where focus and interactivity are the key players, computer graphics helps in providing such features in the efficient way.
education
application of computer graphics
Computer generated models are extremely useful for teaching huge number of concepts and fundamentals in an easy to understand and learn manner. Using computer graphics many educational models can be created through which more interest can be generated among the students regarding the subject.
training
application of computer graphics
visualization
application of computer graphics
Today the need of visualize things have increased drastically, the need of visualization can be seen in many advance technologies , data visualization helps in finding insights of the data , to check and study the behaviour of processes around us we need appropriate visualization which can be achieved through proper usage of computer graphics
image processing
application of computer graphics
Various kinds of photographs or images require editing in order to be used in different places. Processing of existing images into refined ones for better interpretation is one of the many applications of computer graphics.
machine drawing
application of computer graphics
Computer graphics is very frequently used for designing, modifying and creation of various parts of machine and the whole machine itself, the main reason behind using computer graphics for this purpose is the precision and clarity we get from such drawing is ultimate and extremely desired for the safe manufacturing of machine using these drawings.
graphical user interface
application of computer graphics
The use of pictures, images, icons, pop-up menus, graphical objects helps in creating a user friendly environment where working is easy and pleasant, using computer graphics we can create such an atmosphere where everything can be automated and anyone can get the desired action performed in an easy fashion.
raster graphics
These graphics are made up of tiny colored dots or squares called pixels.
