I have made progress with the smoke and some (but less) with the fire. It looks pretty good now (from selected viewpoints :) http://fgfs.i-net.hu/modules/xcgal/displayimage.php?pid=64&album=15&pos=5 and has a bit of LOD control (for smoke only so far). I think I can replace the fires with lightweight static objects at longer distances or densities without much visual degradation. That'll reduce the frame rate impact. Currently my system buckles at around 100 burning cells. Burned out cells don't cost much anymore - I have had thousands of those. I have added (somewhat simplistic) support for water and fire retardant drops, but they are not visible on the ground yet. I'm planning to experiment with that next. I've also modified Gerard's beautiful Catalina to report the water impacts to the forest_fire module. Here is the latest version (temporary location, I expect to get my normal web server back in order during easter): http://www.mpi-inf.mpg.de/~anderg/stuff/ForestFire-20080318.tar.gz Some more screenshots from yesterday night: http://fgfs.i-net.hu/modules/xcgal/displayimage.php?pid=70&album=15&pos=10 (and onwards) Csaba and I tried to tackle a what seemed like a puny little fire. But our slow initial respons (had to load the Catalinas with water..) allowed it to become an unmanageable blazing inferno - after an hour we had to give up.. (despite the Catalina bug that allows an infinite number of drops once loaded with water :) Cheers, Anders -- --------------------------------------------------------------------------- Anders Gidenstam mail: anders(at)gidenstam.org WWW: http://www.gidenstam.org/FlightGear/ ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
