Ok, "crude" works for me as long as it is descriptive!

In cartesian coordinates, The equation of the points on a circle is (x − a)**2 + (y − b)**2 = r**2 where a and b are the coordinates of the center (a, b) and r is the radius. Points within the circle are solutions where x,y result in <= r**2. So this question is given a grid of Horizontal x Vertical discrete points, an x,y "bomb target point" and a radius. The idea is to "color", i.e. fill-in the circle or change all elements to x that are within the circle. The resulting "picture" will look more and more like a smooth circle as the number of elements in the grid increases.

This sort of thing has to happen all the time in video games and I'm sure there are very good algorithms for this. To write my own code, I need to think some more. But, thanks for making the requirement more clear!

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
