Vector Graphics

Composed of objects not pixelsObject oriented graphics = vector graphicsStores a series of mathematical equationsVector graphics can be:

Edited Scaled Repositioned Recolored Exported as bitmaps

Zooming vector graphics saves: Time Data storage

Useful for mapping dataCan be easily scaledNo quality lossVector graphics need faster computer

processors Mathematically complex equations Curved shapes Constructing to many individual vectors

3D Vector Images

Vectors create 3d images Video games Film Television networks

Architects use vector graphics in CAD to: Create 3D drawings Develop products Create physics tests

The CAD program allows designers to: Create physical properties of 3D modles

Weight Strength Material

Graphics In the Movies

(CGI) used to create: Animations Special effects Realism

Motion capture Textures create realism

Balance between detail and mathematical complexity Creates required level of detail (grass)

3D graphic properties: Hardness Reflectivity Smoothness

Intensity of light and colors can be added To produce high quality render farms improve it

Render farms ( thousands of computers improving processing)

Video Formats

Audio Video Interleave : lossy compressionMOV : popular of Apple hardware/ created by

a digital cameraMP4 :more effective lossy compressionMWV: Microsoft's video format

Audio Formats

ACC: developed by Apple uses lossy compression

FLAC: open file format with lossy compression

MP3: sharing site uses lossy compressionWAV: standard or audio softwareWMA: Developed by Microsoft supports

streamed videos and lossy

Image Formats

Bitmap Image: lossless compressionTagged image file format: professionally

published/ printed uses lossless compressionGIF: its obsolete and uses lossless compressionPNG: New lossless format that replaces GIFJPEG: Common lossy file PSD: Adobe’s custom propriety file formatRAW/CR2: More colorful information produced

by SLR camerasSVG: New format supporting vector graphics
