I'm fairly new to Performer but I've been in the real time simulation domain
for a while. After reading part I of the IRIS Performer Programming Guide, I
have full of questions to ask. Here is the first one.
Our application requires very large databases - one covers 1100 km by 900 km.
It's clearly not possible to load the entire database in memory at init time.
Our approach consist in having a separate loader whose task is to monitor the
viewpoint and to load the surrounding tiles. At every iteration, the whole
Performer hierarchy is rebuilt from the loaded tiles. Is there a better way of
approaching the problem? How can the Performer hierarchy be updated at run time
with new terrain data and how can we remove old data from it?
