Re: [osg-users] [osgOcean] Wake effects?
Hi, I'm bringing back this thread up also after 2 years. Did anyone get any success about the wake effect? I'm working around foam+shoreline without any interesting results at moment Thank you!

hi, i get the same question about this.would you get a good solution ? ErikJohnson wrote: Hi, I thought this would have come up before, but does anyone have suggestions how to render a boat's wake?

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 tianxiao...@foxmail.com: 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. 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?
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.

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
