Understanding Images:
An image is a combination of objects, lights, and a viewer.
Methods for acquiring digital images include:
Scanner
Digital cameras
Computer graphics
Image Synthesis:
Refers to the construction of images from scratch.
Rendering refers to the synthesis of 2D images from a 3D scene description.
What is Computer Graphics?
Definition:
Creation, storage, and manipulation of models and images by a computer.
Involves generating 2D images of a 3D world represented in a computer.
Tasks include:
Modeling:
Creating and representing geometry.
Rendering:
Generating 2D images from 3D objects.
Animation:
Describing how objects change over time.
Differences Between 2D and 3D Graphics:
2D Graphics:
Flat images, with (x, y) color values.
3D Graphics:
Objects have depth, represented by (x, y, z) coordinates.
Importance and Applications of Computer Graphics:
Rapid and economical production of pictures using computers.
Wide range of applications:
Graphics presentation
User interfaces
Image processing
Virtual reality
Games and entertainment
Applications in Detail:
Data Visualization:
Used in scientific, business, and medical fields to analyze complex processes.
Graphs and Charts:
Visual representation of statistics and data.
Computer-Aided Design (CAD):
Used in engineering and architectural design processes.
Virtual Reality:
Creating interactive 3D environments.
Training Applications:
Simulations for pilot and ship captain training.
Computer Graphics vs. Computer Vision:
Computer Vision (CV):
Focuses on extracting useful information from images and analyzing it.
Computer Graphics (CG):
Deals with synthesizing images from models using algorithms.
Key Components of a Graphics System:
Input Devices (e.g., mouse, keyboard)
Central Processing Unit (CPU)
Graphics Processing Unit (GPU)
Memory
Frame Buffer
Output Devices (e.g., monitors)
Input Devices:
Physical:
Keyboard, pointing devices (mouse, light pen, etc.).
Touchscreens, graphic tablets, image scanners.
Logical:
String device, locator, widget, valuator.
Graphics Processing Unit (GPU):
Specialized circuit for manipulating and accelerating image creation in a frame buffer.
Frame Buffer:
Storage area for images, represented as a 2D array (matrix of 0s and 1s).
Raster Scan Displays:
Display images as discrete points (pixels) refreshed line by line.
Random Scan Displays:
Draw images using geometrical primitives based on mathematical equations.
Color CRT Monitors:
Utilizes phosphors to display colors; methods include beam penetration and shadow mask.
Display Technologies:
CRT
LCD
OLED
Various display devices like monitors and projectors.
Drawing in OpenGL:
Utilize functions like
glBegin
,
glEnd
,
glVertex2i
etc. to create shapes.
Draw points, lines, triangles, quads, and polygons using OpenGL commands.
