Study Notes
Computer Graphics Overview
- Utilizes computers to create and manipulate images on displays.
- Involves techniques for creating, storing, modifying, and representing images.
Importance of Computer Graphics
- Scenario 1: Shoe manufacturing company visualizes five years of shoe sales using presentation graphics like charts and graphs.
- Scenario 2: Training programs for student pilots employ computer graphics for enhanced simulations.
Applications of Computer Graphics
-
Computer Aided Design (CAD):
- Essential for designing buildings, vehicles, aircraft, and various products.
- Objects initially displayed in wireframe outlines, with software supporting multi-window functionality.
- Enables animations and realistic displays for virtual reality walk-throughs of spaces.
-
Presentation Graphics:
- Creates visual illustrations for reports and projectors.
- Summarizes diverse data types for research, managerial reports, and customer bulletins.
-
Computer Art:
- Integrates fine art and commercial art using programs for painting, CAD, and animation.
- Incorporates techniques for creating digital representations, such as electronic painting and morphing.
Entertainment Sector
-
Movie Industry:
- Utilizes computer graphics in motion pictures, music videos, and animation.
-
Game Industry:
- Focuses on interactivity and cost-efficient production methods.
Computer-Generated Imagery (CGI)
- Involves creating visual content (still or animated) using computer software.
- Encompasses 3D modelling, rendering, and animation for realistic image generation.
Visual Effects (VFX)
- Refers to creating and enhancing visual elements in various media.
- Integrates CGI with live-action, using techniques like compositing, animation, and motion tracking for seamless integration.
Education and Training
- Digital models used as educational tools for physical, financial, and economic systems.
- Employs simulators for practical training of professionals, including pilots and operators of heavy equipment.
Visualization in Business
- Techniques like color coding, contour plots, and charts visually convey data relevant to commerce and industry.
Image Processing
- Combines with computer graphics to enhance visual data representation.
- Important medical applications include image improvement, tomography, and simulations for diagnostic purposes.
- Digitization and processing methods enhance photographic images and facilitate better visual interpretation.
