Study Notes
Introduction
- Computer graphics is the field of study concerned with generating and manipulating images using computers.
- It involves the use of mathematical and computational techniques to create, manipulate, and display visual content.
Key Concepts
- Raster Graphics: Represent images as a grid of pixels, with each pixel having a specific color and intensity.
- Vector Graphics: Represent images using geometric shapes and lines, defined by mathematical equations.
- 2D Graphics: Images are represented in two dimensions, using x and y coordinates.
- 3D Graphics: Images are represented in three dimensions, using x, y, and z coordinates.
Graphics Pipeline
- The process of generating an image on a computer involves several stages:
- Modelling: Creating a mathematical representation of a scene or object.
- Transformations: Applying transformations to the model, such as rotations and translations.
- Viewing: Defining the camera's position and orientation.
- Projection: Projecting the 3D scene onto a 2D image plane.
- Rendering: Calculating the final image, taking into account lighting, shading, and texture.
Rendering Techniques
- Ray Tracing: Simulates the way light behaves in the real world, tracing the path of light as it bounces off objects.
- Scanline Rendering: Divides the image into horizontal lines and renders each line separately.
- Rasterization: Converts 3D models into 2D images, using the graphics processing unit (GPU).
Graphics Hardware
- GPU (Graphics Processing Unit): A specialized computer chip designed for high-performance graphics processing.
- VRAM (Video RAM): A type of memory dedicated to storing graphical data.
Applications
- Computer-Aided Design (CAD): Uses computer graphics to create and manipulate 2D and 3D models.
- Video Games: Utilizes computer graphics to create immersive and interactive environments.
- Scientific Visualization: Uses computer graphics to visualize and analyze complex data.
- Film and Animation: Employs computer graphics to create special effects and animated sequences.
