Re: [osg-users] txp database issue
Hi Robert, I definitely understand not being able to see the issue. I can see the issue and I'm having trouble figuring it out, so it may be a long shot getting anything here, but it's always worth a try! The best way to describe it is that it looks like all 3 LODs just start paging nonstop...almost like it is changing LODs every frame. In any case here is the other information I forgot last post: 1) DB is txp archived version 2.2 2) Culture is externally referenced 3) OSG version 2.8/XP/295GTX/VS2008/Release RelWithDebInfo Thank you!

Re: [osg-users] txp database issue
Robert, Thanks for the ideas. I've been thinking about the expiry scheme change as a possibility, so I'll look into that a bit more (though things have been mostly better for me since the change). Now if I can only find those 2.6 binaries I have laying around somewhere... Thanks again!

Re: [osg-users] txp database issue
Robert, I dug up my 2.6.1 binaries and I can't reproduce the LOD craziness, though I do still see the highest LOD textures eventually go all white (which I'm guessing at this point is a texture memory issue). Anyway, I'll dig further into it as the week progresses. Thanks for your help!

Re: [osg-users] txp database issue
Ryan, Thanks for the hint on the max number of lods. I'll try that when I get back to this later in the week. I've been back and forth trying to determine if it is the txp plugin or not. That code hasn't really changed all that much in the past couple of years, but at the same time, there have definitely been changes made by the vendor to the DB creation tool... Thanks, Steve P.

[osg-users] txp database issue
Hey everyone, I've been running into an issue with txp databases. The problem is that after running for a while the LODs start switching in and out rapidly like the pager can't choose which ones to use. Even when staying still in the scene the LODs continue to switch. It drops framerate down to around 6.0 Hz and the statistics show somewhere between 100-150 ms times for GPU operations (update/draw/cull all look normal). I can't really say what exactly triggers it because the timing of it seems to be somewhat random. Though it does seem to occur when externally referenced models in the DB have been paged out/in multiple times. In addition, the highest LOD textures eventually lose all data and go all white. Any insight would be helpful and much appreciated!

[osg-users] TerraPage Paging Problem
I'm using an unarchived TerraPage DB that seems to never page out. Archived version 2.1 2.2 DBs seem to behave just fine. Unarchived 2.1 DBs don't ever page out. Unarchived 2.2 DBs don't even load (it blows up in the loader with a bad index into an array). Has anyone else seen any of these issues related to unarchived DBs?

[osg-users] [osgPPU] Retrieving an Image from osgPPU
Maybe I'm overlooking something simple, but I just don't seem to see it right off hand. I'm using osgPPU to do multiple passes on a scene and I have the case where I need the result in two ways (I need both simultaneously): 1) To the screen (done with UnitOut) 2) To an osg::Image Case #1 is obviously simple, but I'm having trouble with case #2. I've tried writing a custom unit similar to that of UnitOutCapture without the save to disk, but the call to readImageFromCurrentTexture is extremely slow. Is there a better way to do this?

[osg-users] [osgPPU] Multisampling/RenderBuffer Support
I don't see any support for using RenderBuffer attachments in the osgPPU code. I've used osgPPU for a few things here and there, but I'd really like to take advantage of the on card multisampling capabilities. Is that something that will eventually be implemented?

Re: [osg-users] [osgPPU] Multisampling/RenderBuffer Support
Art, From what I can tell, the multisampling capability already exists in OSG via the Camera's attach function. However, when looking at the RenderStage code, you can see that a different FBO is created to handle the multisampled objects. From runCameraSetup() in RenderStage.cpp: fbo_multisample-setAttachment(buffer, osg::FrameBufferAttachment(new osg::RenderBuffer( width, height, internalFormat, samples, colorSamples))); When multisampling is specified in the camera, a different FBO is set up that specifically attaches to a RenderBuffer target (rather than directly to a texture). I believe that internal FBOs in osgPPU would need to follow that same type of mentality. Does that help to clarify? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=7339#7339 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
