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
