Pengantar Grafika Game

• Term coined by William Fetter, Boeing (1960)http://web.cs.wpi.edu/~matt/courses/cs563/talks/history.html

• Computer Graphics are graphics created

using computers and, more generally,

the representation and manipulation of image data

by a computer

• Secara umum: apapun yang dicitrakan dengan

komputer, dan citra yang dimanipulasi dengan

komputer

Digital Image Processing:

Input: pixels, output: pixels.

Manipulate existing images to achieve desired

visual results (image correction, visual effects,

transparency, image stitching)

Computer Vision:

Input: pixels, output: data.

Read images, manipulate if necessary and

interprets it (segmentation, thinning, edge

detection, isolation, properties extraction)

Computer Graphics:

Input: data, output: pixels.

Create, plot and manipulate images using data to

render analytic visual result (image primitives,

transformations, fractals, 2D and 3D planar

projection)

• Menyajikan informasi dalam bentuk yang mudah

dipahami

GUNA GRAFIKA KOMPUTER

• Memodelkan suatu kondisi secara visual untuk

mempermudah analisis

• Memodelkan suatu kondisi secara visual untuk

mempermudah analisis

• Menciptakan hal-hal yang mustahil, secara visual

• Principles of Light and ColoursColour Models and Colour Rendering Modes

• Principles of Computer GraphicsPicture Elements (pixel)

Can you draw this if you can’t even draw a single line?

If this, just use a pencil ☺
