Study Notes

Computer Graphics Fundamentals

Computer Graphics: The process of creating and manipulating images using computers, involving a combination of art, mathematics, and technology.
Pixel: The smallest unit of a digital image, short for "picture element", which is a tiny square of color that, when combined with others, forms a complete image.
Resolution: The number of pixels present in an image, measured in terms of width and height, e.g., 1024x768, which affects the image's clarity and detail.
Aspect Ratio: The proportional relationship between the width and height of an image, e.g., 4:3 or 16:9, which determines the image's shape and how it is displayed on screens.
Frame Buffer: A region of memory that stores the image data to be displayed on the screen, acting as a buffer between the computer's graphics processing unit and the display device.
