[osg-users] [osgOcean] Wake effects?
Hi, I thought this would have come up before, but does anyone have suggestions how to render a boat's wake? Using osgParticle provides an "ok" solution, but falls apart rapidly if the ocean waves are too large (the particles go underwater). Would be cool to leverage the same texturing effects as the "wave crest foam" stuff - just not sure how. :) Thanks for any suggestions, Erik -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=19849#19849 <>___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] [osgOcean] Wake effects?
Hello Erik, Sorry I missed your post yesterday. There isn't really any support for wakes on the sea surface at the moment, although it's definitely something that needs addressing. However, I just had a submission which uses the depth buffer to add breaking foam to the shoreline. This does sort for work for other objects on sea, like ships, but it doesn't look very pretty at the moment. You're more than welcome to have a play with the effect and see if you can do anything with it. From what I understand what you'd need to do is add a sort of sloped geometry which tracks you your boat, that would get picked up in the depth buffer and the same foam texture used on the wave crests is applied to it. It's been checked into the trunk, but like I say it needs a little work. There was a discussion about it here: http://thread.gmane.org/gmane.comp.graphics.openscenegraph.cvs/6252 Cheers.

Re: [osg-users] [osgOcean] Wake effects?
Hah! I attached an image file via the Forum. For some reason it came across pretty ugly in the email. Looks fine on the Forum. I'll see about the new technique on the trunk - might just have enough time to give it a test! Thanks, Erik Kim Bale wrote: > Oh.. and was the attached image supposed to be in 8 bit colour?

Re: [osg-users] [osgOcean] Wake effects?
Hi Kim, Oh.. and was the attached image supposed to be in 8 bit colour? Are you running osgocean on a zx 81 or something? ;) Looks like images attached to forum posts are converted to lower resolution/bit depth before being sent to the mailing list, it's not the first time I've seen this in the last few weeks. Perhaps this is a setting Art could tune? I don't think our users would purposefully post huge images... Or maybe there could be a resolution limit but keep the original bit depth?

Re: [osg-users] [osgOcean] Wake effects?
Hi Kim: I have seen the dicussions in the page you give. Good works about the foam added to the shoreline. I have update my source from SVN, when I test the new source, I found that the foam effects around the boat is still sharp white. Is that still a unsolved problem?

Re: [osg-users] [osgOcean] Wake effects?
Hello Tian Ma, I have update my source from SVN, when I test the new source, I found that the foam effects around the boat is still sharp white. Is that still a unsolved problem? Yes indeed. We discussed adding (invisible) sloped geometry around the silhouette of objects that contact the water so that the depth buffer around them would go down gradually rather than sharply, kind of the way shadow volume techniques generate geometry for the shadow volumes from silhouette edges as seen from light sources. But this was just discussion. No one has volunteered to do this yet. Any volunteers? :-) J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] [osgOcean] Wake effects?
Hi Tian, Last night I committed the changes that permit alpha tranparencies to be used in conjunction with the glare and depth of field effects. This required the use of multiple render targets ( http://code.google.com/p/osgocean/source/detail?r=183 ) and some changes to some of the shaders. It looks like that's used up the maximum varying attributes of your card and also possibly your card doesn't support MRTs. What graphics card are you using? Could you set the notify level to osg::notifylevel::info and dump the contents to file so I can see exactly what the problem is? Cheers.

Re: [osg-users] [osgOcean] Wake effects?
Ok I reckon the water.frag has used up the maximum allowed uniforms for that card, I've come across this issue before with the 7 series cards. There are some tricks to get around this, so I'll see if I fix it. Is there any chance you could set the notify level to osg::NotifySeverity::INFO and then pipe the output from oceanExample to a file and send it to me? It might tell me how many I've used and are allowed to use on that card. You can do it easily in the command prompt (win32) by using the command oceanExample > ocean_output.txt Regards, Kim. 2009/11/25 Tian Ma : > Hi Kim: > > My graphics card is 'NVIDIA GeForce 7300 LE'. > > The version number <= r181 could work normally on this card. > > And since r182 to 185, the error emerged. > > > Cheers, > Tian > > > > Kim Bale wrote: >> Hi Tian, >> >> Last night I committed the changes that permit alpha tranparencies to >> be used in conjunction with the glare and depth of field effects.

Re: [osg-users] [osgOcean] Wake effects?
Would it be possible to implement sort of a config option with 2 or more shaders for multiple quality levels? This would allow for the use of one shader if you have a more powerful card, or another shader for an older card. Peter -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=20395#20395 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [osgOcean] Wake effects?
Hi Peter, Well this is really what the many weird and wonderful configurable options are for in OceanScene, nearly every effect can be turned off an on to suit the graphics card configuration. I think it's probably better to do it this way, rather than grouping them together to give the low,medium and high settings, as you can fine tune the rendering to suit the available hardware. The core water shader itself isn't so expensive, it's largely the pre render passes that bring down the frame rate and all of these can be turned off and on as desired. (I think) the problem with Tians card at the moment is that the water shader in the trunk has used up all the maximum number of uniforms permitted on nvidia 7 series card which use a version of glsl that I'm not 100% sure of. But I think this can be worked around, I just haven't got round to it yet (plus it's quite hard to test without a suitable card) K. 2009/11/26 Peter Bear : > Would it be possible to implement sort of a config option with 2 or more > shaders for multiple quality levels?

Re: [osg-users] [osgOcean] Wake effects?
Hi Tian, It did highlight some useful stuff. Unfortunately I won't get round to fixing this immediately. However, if you want to use the version in the trunk you can probably get round it by replacing the uniform booleans one by one with hard coded values in the water shader for the options you want to enable until it stop complaining. Obviously this is a temporary fix until I get round to investigating further.

Hi Tian, Could you download and run this program for me: http://www.geeks3d.com/20090414/gpu-caps-viewer-170-available-with-cuda-support/ And then use the "Full XML Export" tool under the "Tools" tab and then send me the xml file please. I need to know exactly what your card supports and I can't seem to find out from my searches. Cheers. Kim. 2009/11/27 Tian Ma : > Hi Kim: > > Thank you! > > By now, I am using the olde version.
