Bresenham's line algorithm is a method for determining which pixels to include in a line between two given points on a grid. It works by calculating the slope of the line and then using a decision variable to determine which pixels should be included. The algorithm then adjusts the decision variable as it moves along the line to ensure that the line stays as straight as possible.
The main advantage of Bresenham's algorithm is its efficiency. Unlike other line-drawing algorithms, it only uses integer calculations and does not require any floating-point operations. This makes it faster and more suitable for use in computer graphics.
No, Bresenham's algorithm is designed specifically for drawing straight lines on a grid. It cannot be used for curves or other non-linear shapes.
One limitation of Bresenham's algorithm is that it can only draw lines at angles that are multiples of 45 degrees. This means that diagonal lines may not appear as smooth as other lines. Another limitation is that it does not take into account the thickness of the line being drawn, so thicker lines may appear jagged.
Bresenham's algorithm is commonly used in computer graphics for drawing lines and shapes on a grid. It is often used in applications such as video games, computer-aided design (CAD), and image processing. It is also used in printers and plotters to accurately draw lines and curves on paper.
