Re: [osg-users] [osgOcean] OSGOcean reflection is not mirrored
Hi Chris, When you get a sec, could you post a screen shot so I see exactly what's going on? Cheers, K.

Re: [osg-users] [osgOcean] OSGOcean reflection is not mirrored
Maybe I was thinking of the latest osgEarth then... Anyway, I made that change to add the override to the cull face setting, but I still see the reflection of the underside of my landscape once I'm higher than the water is deep. If we weren't in the process of locking down code for a demo, I'd upgrade to the latest osgOcean. For now, I'll just move the land out of the ocean's branch so it isn't included in the reflections. I'll come back to this problem later.

Re: [osg-users] [osgOcean] OSGOcean reflection is not mirrored
Hi Chris, Not at all I've been using 2.8.2 for ages with osgOcean and it's been working fine here :) I think you're getting mixed up with the VBO branch which has problems getting along with 2.9.7 K.

Re: [osg-users] [osgOcean] OSGOcean reflection is not mirrored
I'm stuck with the last "stable" release of OSG, v2.8.2, and if I recall correctly, the most recent osgOcean requires something later, yes? Maybe I can mix and match a bit... But yes, it IS a reflection of the back face of the terrain. ~ Chris Innanen ~ Nonsanity -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=28166#28166 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [osgOcean] OSGOcean reflection is not mirrored
Hi Chris, How old is this post?! The height of the reflection clip plane is set in OceanScene.cpp around line 412. osg::ClipPlane* reflClipPlane = new osg::ClipPlane(); reflClipPlane->setClipPlaneNum(0); reflClipPlane->setClipPlane( 0.0, 0.0, 1.0, -getOceanSurfaceHeight() ); _reflectionClipNode = new osg::ClipNode; It should be pretty easy to add a mutator to offset it, if you do send it in and I'll merge it. Also have you tried the version in the trunk? I fixed a strange reflection issue a while back where it seemed that you were seeing the interior but in fact it was due me forgetting to disable back face culling on the reflection pass.

Kim Bale wrote: > Yes I believe you're seeing the underside of your terrain in the water > there, a result of the clip plane being set too low. I think this is exactly what I'm seeing at the moment. I'm using osgEarth to create the terrain, and if the camera is over the water at a height less than the depth of the water at that point, it all looks fine. If the camera's height above the water is greater than the depth, then I see the underside of the terrain, including the seams. It's a strange and disconcerting effect when flying over the water. :) But it's something I need to get rid of. Clip plane being set too low... I thought at first I knew what that meant I had to do to fix this, but I appear to be wrong.
