What is midpoint circle generation algorithm?

The midpoint circle generation algorithm is a method used in computer graphics to draw a circle using incremental calculations based on the circle's symmetry. It works by calculating the pixel positions of a circle's circumference in the first octant and then mirroring these points across the other seven octants. The algorithm uses integer arithmetic to determine when to increment the y-coordinate while maintaining the circle's shape, which results in efficient rendering with minimal computational overhead. This approach reduces the need for floating-point operations, making it suitable for raster graphics applications.
