In computer graphics, a point is a single, isolated coordinate in two-dimensional or three-dimensional space. It is the most basic element of a digital image, represented by a single pixel on a screen. Points are typically represented by their X, Y, and Z coordinates in 3D space and are often used to represent vertices or endpoints of geometric shapes and lines.
A line, on the other hand, is a collection of connected points that form a straight path between two endpoints. It is defined by two or more points, and the line itself does not have any thickness or width. In computer graphics, lines are often used to create shapes, such as polygons and curves, and are fundamental to creating images and geometric shapes.
Both points and lines are basic building blocks in computer graphics, and they can be used to create more complex shapes, such as curves, surfaces, and solid objects. They are also used in algorithms for various applications such as computer vision, image processing, and machine learning.
