### Bresenham circle drawing algorithm, compute the distance?

In the Bresenham circle drawing algorithm, we have to choose between the top and bottom pixel, but what we always do is using the circle's equation ($f(x, y) = x^2 + y^2 = r^2$) to determine which of ...

### What is the point of having integer-based draw routines in software rasterizer?

I wonder why all the well known algorithms of drawing for example circles (bresenham, mid-point, etc) all use integer arithmetics? For example, here is a simple circle drawn with bresenham algorithm: ...

### Midpoint Algorithm Fast Direction

I've been exploring the Midpoint algorithm for drawing lines and curves, and I have a quick question: How should you determine the fast direction for a curve? I've seen that if the shape is simple, ...
I've the following problem: Let the camera opening angle be $\frac{3}{4}\pi$ and the window be $15 \times 15$ pixels large. Which pixels does the midpoint algorithm (without anti-aliasing) set for ...
