Hi
I'm currently writing a layer that animates OMGraphics on the map and is
driven by a remote server sending update events every second.
Unfortunately when I have about 10 graphics moving around, updating every
second, the fast dual processor machine it is running on can hardly cope!
Obviously calling repaint() on the entire map takes way too long, so I am
calculating the invalidated area of the map for each moved graphic and
calling repaintChildren() for that area on the BufferedMapBean. Not only is
this not fast enough but it also brings with it a whole world of problems
with other layers not getting refreshed properly because the clipping area
has changed.
There must be a way of improving the performance beyond this. Does anyone
have any tips?
Thanks in advance
Jim
