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.

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.

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).
