- What is the best (a good) algorithm to determine if a point (x,y)
- is contained within a circle of given center (x,y) and radius (r)?
-
- Also, what is the best (again, a good) algorithm to determine if
- a circle (x,y,r) is contained completely and/or partially within
- a bounding circle (x,y,r)?
-
- Finally, what is the easiest way to determine if circle A
- intersects circle B at any point?
-
- Many thanks in advance to all the circle experts out there...
-
- Cheers!
