Re: [Flightgear-devel] Global weather clouds
Hi Curt, I've managed to find the problem, and once I get git to play ball, I'll make a merge request! If you've got a list of the 3D clouds bugs you've found and not fixed yourself, I'd be interested in fixing them. The flying trip was fantastic. We flew just over 1000 miles over 8 days (19 hours of flying). By far the longest trip I've done and a great challenge.

Re: [Flightgear-devel] Global weather clouds
Hi Stuart, Great to hear you figured out the elevation issue. Those were the two issues that I noticed: - cloud elevations off - overcast cloud layers not drawn at all One other that I haven't paid close attention to, but one time I wondered if the cloud layer had slid off to the far end of the sky? Someday I hope to get my license, and then have this dream of buying an airplane 1000 miles away and having to ferry it back cross country. Once in a while (maybe a couple times a day) :-) I go online and look at little classic 2 seater airplanes that are for sale for $20,000 and dream -- but I probably should get my pilots license before I buy an airplane, and if I buy an airplane that isn't a total piece of junk then I need a hangar to store it and a way to pay the recurring maintenance costs. I live in a big city so hangar space close by is in high demand and expensive ... so I probably need to get a real job first, but then I won't have time to take lessons and fly, so I might as well just forget about the whole thing and have fun playing on my computer and flying my little model airplanes. :-) Curt.

Re: [Flightgear-devel] Global weather clouds
Hi, Was also looking over Thorsten's pics and writeup on the FG forum (assume those were the pics referenced) and wondering how to go about setting up the cloud scenery. Looked over the README.3DClouds writeup and that pretty much answered the howto but was unable to find any complete xml files (simple or complex) to start from. Are there any available? Two related questions: 1) how does one enable (use) the hi-res texture files? and 2) where (how) are the shader programs enabled?

Re: [Flightgear-devel] Global weather clouds
See Environment/cloudlayers.xml for the cloud definitions used in the global 3D clouds. Found it, so assume you need to add a reference in the preferences.xml file to include this xml file for cloud types, correct? Two related questions: 1) how does one enable (use) the hi-res texture files? and I don't recall whether the 3D clouds code uses the hi-rez textures at all. Sorry. 2) where (how) are the shader programs enabled? If you enable the 3D clouds from the View-Rendering Options menu you should see them. Yes, have been able to get the 3D clouds working in 2.0 and now finally understand how they are actually instantiated and now how to incorporate the additional cloud types. Thanks again. I should have been more explicit in the hi-res questions, Trying to understand how to use these hi-res textures for terrain features. If anyone understands this area any help would be appreciated. Looked over the doc for effects and shaders; kind of get the gist of the writeup, but still a bit fuzzy on understanding the actual implementation..

Re: [Flightgear-devel] Global weather clouds
Hi Curt, I've been looking at the altitude problem all evening, but haven't (yet) found the bug. AFAICT the correct altitude (in m) is being passed down the stack and used to create an altitude offset, so it's not just a case of the stack using the height of the clouds rather than the altitude. It looks like there is a further offset elsewhere of the airport altitude that's causing the error, but I've yet to find it. Just so you know I'm not ignoring this... -Stuart On Thu, Apr 28, 2011 at 9:32 PM, Curtis Olson curtol...@gmail.com wrote: Hi Stuart, I saw that you recently made some updates and bug fixes to the global weather 3d clouds including fixing a problem with overcast coverage and also making clouds drift with the wind.

Re: [Flightgear-devel] Global weather clouds
Hi Stuart, thanks for taking a look. How was your trip? Hope you logged a lot of nice flying days! Our weather has been pretty much crap around here and then the nice days I've had to work or had family stuff, so I've logged about 5 minutes of (RC) stick time so far in 2011. :-( Curt.
