[ka-Map-users] Point Collision

[Wei Yang, Ng - Wayne]

Hi Pg,
      Will you be working on a point collision system for your overlay 
code? If not, I would like to try creating one. Any pointers or hints?
The collision stuff will be triggered by a flag set by the XML document.
    If we want collision detection on, the points will be created but 
will remain hidden (using style.display = none) first while we determine 
which points should be displayed and which should remain hidden. The 
colliding hidden points can then be represented by only one point. (1 
point to represent many points within the user-defined region.) I have 
thought of possible problems that may arise, such as collision chains. 
We wouldnt want a long string of colliding points to be represented by 
only 1 point.

    Anyway, I could start of by defining an imaginary collision 
detecting square around a point first and work my way up as stuff 
hopefully works.

Cheers,
Wayne
