What is Computer Graphics?

Question	Answer
Computer Graphics	a sub-field of computer science which studies methods in digitally synthesizing and manipulating visual content
Application Domain	1. Entertainment 2. Mechanical Engineering 3. Medicine 4. Design 5. Architecture 6. Cultural Heritage
Areas of Computer Graphics	1. Imaging 2. 3D Scanning 3. Geometric Modeling 4. Geometric Processing 5. Animation & Simulation 6. Computational Photography 7. Rendering
Color	fundamental aspect in computer graphics
Color Analysis	can occur in physical and perceptual level
Additive Color Mixing	- colors created with diff colored light - used for device displays
Subtractive Color Mixing	- colors created by specific wavelengths of light - used for printing
rod	monochromatic, sensitive to small amounts of light
cone	color receptors, less sensitive to light
raster image	rectangular set of colorized pixels that represents the objects in an image
vector image	objects in an image that is represented by object primitives such points, edge, triangle, polygon, etc
rays casting	steps: 1. the eye releases a ray of light 2. the ray intersects an object 2.1. the ray is then bounced to a light source 3. the closest points are collected 4. calculate the sets of closest points
rasterized image pipelining	steps: 1. get data 2. geom transformations and attr setup 3. processing 4. rasterization 5. computation 6. pass to framebuffer
color matching	process of transferring a particular across diff tech and platforms
