I've implemented the snow shader effect into lightfield rendering yesterday - this looks quite promising already:
http://www.flightgear.org/forums/viewtopic.php?f=47&t=14755&start=165#p155463 but I have a few questions I've come across? I've tried to use /environment/snow-level-m to control the effect initially, but it turned out I can't set that while Advanced Weather was running, even with METAR mode off. I've then introduced my own alternative snowline property that I can test the effect properly, but that's not a particularly smart solution. Basically, I want to be able to set /environment/snow-level-m via the Advanced Weather menu as well while the system is running. Can anyone give me a brief introduction into the logic that controls the snowline currently so that I can decide how to best approach this? Also, I was wondering about changing the snowline dependent if the surface is facing south or north. Do we know in model space where south is, in other words, are the terrain tiles loaded in a well-defined orientation like (1,0,0) points west or so, or is there some unpredictable offset involved? The noise texture seems a very useful technique for all sorts of things - does anyone know a short writeup about what exactly it does (at what scale is noise generated, by what algorithm, ...)? - maybe I can use something like that to get some variation into the apparent fog density and distort the horizon line a bit for a more realistic effect. Also, debugging was unusually tough because since a while ago my console is flooded by messages calculating estimated arrival times after a minute or so and the messages I've been waiting for are lost - is that the AI system (which was actually set to off on startup by property)? Can we get rid of this? Thanks in advance for any help, * Thorsten ------------------------------------------------------------------------------ For Developers, A Lot Can Happen In A Second.
