Re: [Flightgear-devel] 3D Clouds - progress report
I tried the imposters/billboards patch fro 3d clouds but didn't get the problem you reported. It does make flightgear dog-slow however, 1 or 2 fps maximum. I played a bit with the rendering options but none of the options did make any difference in frame rate (not even setting the cloud settings to their lowest values). In fact, setting it to their highest values gave the same framerates; 1 or 2. Since it does show 2 frames per second very often I do have the feeling this might be a culling problem of some sort. What I did notice however is that specular reflections are also applied to the terrain with the OSG branch which might be a bad idea since that is inherently a slow process if I understand it correctly.

[Flightgear-devel] 3D Clouds - progress report
Hi All, As I mentioned in my mail yesterday, I'm taking another look at 3D clouds. Rather than using Impostors, I instead looked at what I could do by using GPU shaders - basically offloading as much processing onto the graphics card as possible. This worked very well for the random-forests, which is in some ways a similar problem - needing to generate huge numbers of very similar pieces of simple geometry. Here's a current screenshot showing my progress: http://www.nanjika.co.uk/flightgear/clouds.jpg So far, I haven't noticed any effect on performance at all. There are still quite a few bugs to be ironed out, but I think I will be finished by Christmas. -Stuart - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

Seems like a classic thing to investigate (along with about a hundred other potential graphical improvements) once there's an OSG release out in the world - I'm hopeful that messing around with aspects of the rendering (whether it be specular highlights, shadows, precipitation, impostors or clouds) will be easier with the new, much more modern scene-graph. But we need to walk before we can run (or an equivalent flying analogy), and get an OSG release out.

So much as I know it was the starting for 3d-clouds rendering in realtime, and the MSFS- clouds are based on Mark Harris idea. But so far as I can remember there was an issue with framesrates? It was a short time in FGFS, right? Maybe we can use different types of cloud rendering- Mark Harris clouds looks fantastic for Cumulonimbus- would like to see different types of clouds which appears realistic to the type of weather (by METAR?)

Did a "half-baked" version of Mark's code a few years back ( never got my head around the plib scene graph stuff even with lots of help from Curt and friends ). Still the visual effects were quite realistic, especially when emerging from a cloud as it thinned and the terrain became visible and the opacity can be varied with the code.A nice feature for investigating the problems associated with transitioning from an IMC instrument approach to visual conditions for flare and landing.

Doesn't look bad at all. The main visual problem may be the textures, which are completely opaque. Real clouds tend to increase transparency towards the border. Just my 2ct.

[Flightgear-devel] 3D clouds - progress report·
Hi All, Just to keep everyone up to date on where I am with porting 3D clouds to FG OSG: http://www.nanjika.co.uk/flightgear/clouds.jpg Obviously there is still a lot of work to be done before they are complete, but progress is being made. I'm hoping that once I've completed the OSG part of the work I can get my changes checked in and other people will be able to enhance it further for things like weather radar. -Stuart __ Not happy with your email address?.
