I am working with the following scenario and I have a question which
follows:
I'm using pfdNewCircles with 16 triangles (GeoSets) to represent blips
on a radar. The radar has some range, X, whereby objects that are
further away than X do not appear on the radar. The GeoSets are
attached to Geodes, which are attached to DCSes.
Which of the following is more costly to implement when items move out
of range and should disappear from the radar:
1. Draw the pfdNewCircles all the time and just move their DCSs'
translation matrices to some whacked out location like (-10000, -10000,
-10000)?
2. Draw the pfdNewCircles all the time and make their GeoSets'
GeoStates transparent?
3. Call pfDCS->removeChild and remove the blipDCSes from the radar
(also a DCS);
Thanks! - Kevin
