Some progress and minor issues: I am in the process of redoing textures and cloud definitions for Cu layers (the toughest nut), about halfway through converting all available cloud types.
I have implemented tested tile management functionality (automatic building and removing clouds) and it seems to be working fine. The new geodinfo() works great - many thanks for that! - it speeds up the system considerably. Not to the point that all could be done in a single frame without generating a noticeable delay, so I'll have to write some routines to split it over maybe 10-20 frames (much better than 30 seconds though). I've noticed that 3dcloud.vert contains the line fogFactor = exp( -gl_Fog.density * fogCoord * 0.5); which tends to fade distant clouds to transparent dependent on visibility range. I find the visual impression better if the 0.5 is changed to a lower value, say 0.3 or even 0.2. Is there a reason to keep it at 0.5, or could we lower it? Also, at one point Stuart told me that the y-position of a texture on the texture sheet is correlated with the position the sprite gets in the cloud - is this something I should be aware of? For some cloud types, this may be useful, but for others it makes no sense. In particular the Congestus type images are much broader than high, so they are arranged in a 1x3 pattern on the sheet, but I don't really want the same texture to always form the cloud top. In any case - I take the opportunity to say thanks for all the help - I think the system is moving a big step forward right now.
