I suspect I know what this is doing:
Can you put it into words so maybe I can confirm my suspicions.

from StackOverFlow
void circle(Point p, int r) {
int x = 0;
int y = r;
int f = 1-r;
// plot vert/horiz points indepedently
while (x<y) {
x++;
if (f<0) {
f += 2*x+1;
} else {
y--;
f += 2*(x-y+1);
}
glRecti(p.x+x, p.y+y, p.x+x+1, p.y+y+1);
// plot other points using 8 way symmetry
// attempt to fill the circle - didn't go well
plotLine(Point(p.x, p.y+x), Point(p.x+x, p.y+x));
}
}
Update: that code is wrong! "didn't go well" indeed!
which looks more like vince version!
No creators here just copiers LOL we stand on shoulders of other great copiers.
BTW I was just watching argument of Creationist against evolution because I got into discussion about man not evolving from ape but BOTH evolving from a common ancestor species down the tree of Life.
Code: (Select All)
e = e + 2 * y0
else
e = e - 2 * x0Can you put it into words so maybe I can confirm my suspicions.
