Study Notes
Rendering Technology
- Deals with the visualization of images in computer graphics, excluding text elements.
- Involves techniques and processes to transform 3D models into 2D images, often using software such as OpenGL or DirectX.
Information Visualization Applications
- Utilizes maps and building plans to visually represent data and information.
- Enhances understanding and analysis by providing visual context and spatial relationships.
Raster Graphics Units
- The basic unit of a raster in a graphics system is known as a pixel (picture element).
- Pixels are the smallest discrete elements that make up an image, each having a specific color and brightness.
24-bit Color System
- Composed of three color channels: red, green, and blue (RGB), with each channel containing 8 bits.
- Allows for approximately 16.7 million distinct colors, enabling detailed color representation in digital images.
Camera Model in Computer Graphics
- Described as a pinhole camera, represented as an opaque box with a small aperture or center of projection.
- This simplified model helps in understanding image formation processes in scenarios such as ray tracing.
