I know that you can use Circle(, but does anyone have a basic code that can do it?
Umm... Not really, however..

Circle(X,Y,R,{i

That draws them really, really fast Very Happy
I knews that Very Happy
But I want to make a circle shader, but I have no idea how to make a circle.

ZOMG SORCERY.

Accessed through Math, right?

And by the way, why does this work?

Well, you could just calculate the coordinates for a line originating from the center of the circle and draw a line from there to the inverse of it, then increase the angle every cycle.

Yes, I'm aware this would take several weeks.

Yes, I'm aware this is a terrible idea.

I'll show myself the door.
That's kind of the thing I am trying to find out.
And I believe that {i} triggers a "fast circle drawing flag".
Yeah, it does set it.

You're welcome to take a look at my Bresenham circle program, based on an algorithm that Kllrnohj discovered elsewhere.

Unless you're trying to write one from scratch, something like this should work:

"sqrt(9-X^2->Y1
Shade(-Y1,Y1,-3,3

(where here 3 is the radius, and 9 is the radius squared)

Just to nitpick, what's wrong with:


Code:
"sqrt(9-X^2
Shade("-"+Ans,Ans,-3,3


It's been a while since I tried anything like this, so that's highly likely to be invalid.
