Questions and Answers
What is the midpoint algorithm used for?
What does the midpoint algorithm assume about the line being rasterized?
What is a key advantage of the midpoint algorithm?
Study Notes
- The midpoint algorithm is for rasterizing lines on a computer screen.
- It calculates the coordinates of pixels the line intersects.
- It assumes the line has a positive slope.
- It can be modified for lines with negative slopes.
- The algorithm calculates the difference in x and y coordinates.
- It initializes the decision parameter d.
- It draws the first pixel and sets the current x and y coordinates.
- It updates the decision parameter d for each pixel along the line.
- It uses only integer arithmetic and avoids floating-point calculations.
- The algorithm is efficient and can be implemented using simple integer operations.
