Re: [osg-users] Best ways to render FE models with millions of tris and quads
Hi Andrew, For this type of task I would use VBO's and in conjunction with DrawElementsUint() usage. Breaking up the model in to spatial zones so that rather than having one very large osg::Geometry you have a whole series of osg::Geometry each with a modest number of vertices - I've found around 10,000 a pretty useful target of models with millions of vertices on screen. The advantage of segmenting the model in this way is that it aid view frustum culling and provides the OpenGL driver and hardware the ability to manage the memory asynchronously if and when it needs to copy the data. W.r.t DrawElementUint() you may well find that just using single block of DrawElementUint(GL_TRIANGLES) is sufficient, and the indices you'll be able to map back to your original primitives. Robert.

These models may have milllions of nodes and elements ( triangles and quads), with usually simple shading. I am replacing some custom OpenGL code (hard to maintain, not clean C++) with OSG ( easy to maintain, well written C++) For example, with one particular model, the old custom code which basically just held a vertex array and sent the primitives down the pipeline used about 650M of memory. The OSG version with no optimization of the primitives and using display lists used 1.3G of memory. Turning on optimization, and turning off display lists brought that down to 850M. Turning display lists back on, cost about 200M. The big problem with optimizing the geometry , is that one loses the ability to pick as all association of the primitive index with the original geometry is lost... Obviously there is always a memory/speed trade-off here, but perhaps someone has been this way before and has some best practices advice.

[osg-users] [osgPPU] Problem Passing Lookup Table to Processing Unit
Dear Mr. Art Tevs, I am trying to pass a GL_RGB texture to one of the Proceessing units for Lookup table. I attach a shader to the processing unit to compute the final color. The scheme works when I attach the shader to the scenegraph and access the lookup texture thererin. However when I attach the shader to the processing unit, the results are unexpected and I see the openGL warning. Do I have to use UnitTexture to pass the lookup table? I am totally stuck in dark. Please help. Thanks Regards Harash ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] OSG Talent Available? (internship planning)
Hi all, I have two questions, but I'll post them separately as they really don't belong in the same thread. Here's the first... I'm horribly noob to OSG, but it's obvious this is pretty good stuff and a capability I could really use. I'm heading up the second year of a 3D visualization related testbench project at work. I will have budget for an intern or two this coming summer (June-Aug 2010). I have a pretty good feeling that if I tell my HR department I need OSG expertise, they'll just give me a blank stare and ask OMG? What's OMG? ;) What's the best way of getting in touch with some talented OSG student-types who would be interested in a summer gig in Aerospace? (or is this it?) Thank you!

Re: [osg-users] [osgPPU] Problem Passing Lookup Table to Processing Unit
Hi Harash, First take a look into documentation of osgPPU. osgPPU is very well documented, look here (http://projects.tevs.eu/osgppu and http://www.tevs.eu/doc/osgPPU/namespaceosgPPU.html) If this does not help you, then take a look into examples. Every example has tons of comments to help new users to understand how certain things works. Harash Sharma wrote: ...However when I attach the shader to the processing unit, the results are unexpected and I see the openGL warning. Do I have to use UnitTexture to pass the lookup table? I am totally stuck in dark. Please help. Attaching a shader to a unit does works fine. In every example you can see this behaviour. So it might be that you are doing something wrong with the setup of your shader. If you want to have a texture as input to any unit, then you have to use UnitTexture instead. You just put a UnitTexture under the processor and call unitTexture::setTexture(_myTexture) with your texture. Then any unit which is a child of that unit texture will have this texture as input.

Most of the types you're trying to handle are Nodes as superclass. Probably you'll have to use getNode for the case and than verify the class with dynamic_cast or className() that is a member from Node if you want to retrieve the class type.

[osg-users] OpenGL ES-2.0, OpenGL ES-1.1 and OpenGL 3.x support now ready for testing :-)
Hi All, Over the past week I've had my head down beavering away on porting the OpenSceneGraph across to work on OpenGL ES 2.0, this bulk of this work is now complete and checked into svn/trunk. While doing the refactoring work I also took the opportunity to add support for OpenGL ES 1.1, and open the door to supporting OpenGL 3.x - a door which Paul Martz walked through and completed the refit/decorating ;-) With the bulk of the porting work done and checked my focus will now turn back towards the community, both in looking for assistance on testing these new OpenGL targets out, and also porting across to different embedded and desktop platforms. For instance I now know that the OSG is compiling under QNX with OpenGL ES, but alas we don't yet have any CMake build support in place, also now we support OpenGL ES it should be possible to provide a port to the iPhone/iTouch and other embedded platforms. Support for creating graphics GL3 contexts under GLX isn't yet done as well. I don't have the hardware/SDK to try out all these different targets, but this is why the OSG community has been historically very strong - almost all out platform ports have been done by members of the community. If you have the itch in any of these areas please chip into this thread and we can coordinate out efforts. Another side of my finally being able wrap up the OpenGL ES ports is that I'll finally have much more scope for catching up with osg-submissions, and start getting dev releases out the door and work towards getting the next stable release out. There should also be more opportunities for me to chase up on various outstanding design/implementation issues. Please be patient though, I can't suddenly tackle everything at once - my first priority is getting up to date with submissions and a dev release out the door, and tidying up the new OpenGL ES ports.

Re: [osg-users] Please Help with Setup
Chris, I was able to get VPBMaster-0.9.10 installed and built on Sunday with OSG-2.8.0. I believe I'm pretty close to the solution I'm looking for but I just had a couple more questions about how to use VPBMaster now. For the prior version of OSGDem that we were using, my co-worker added some code so that he could pass an arguments file to OSGDem containing the commands for each Bitmap (490 bitmaps total). This args file was built by a tool that he wrote that generates those 490 bitmaps from OpenFlight data we receive from our customer. For one bitmap, we have the following arguments: --xt -507904 --yt -569344 --xx 64 --yy 64 -t E:\Map_DB\LeftHalf\X-507904_Y-569344_R4_I-1.bmp with: -l 12 -o E:\Map_DB\LeftHalf_ive\LeftHalf.ive I modified the path for the bitmap file a little, but this is basically what we were passing into OSGDem for each bitmap. I'm wondering what I need to do with VPBMaster to be able to pass in 4900 arguments by using an args file like we were with the older OSGDem. Is this functionality already built into VPBMaster, or can I add similar code to what we had before that will handle it? I was looking at the main function in vpbmaster.cpp and it looks similar to OSGDem's, so I was hoping it'd be pretty close, but I'm not sure what the --build and --to commands are for. I'm wondering if I need to modify my args file to include those arguments or not? Any help is appreciated!

Re: [osg-users] Best ways to render FE models with millions of tris and quads
Hi Robert, With optimization I mean calling something like osgUtil::Optimizer optimizer; optimizer.optimize(osgAssembly_,osgUtil::Optimizer::DEFAULT_OPTIMIZATIONS ); Anyway, I did my own optimization to create the absolute minimum number of PrimitiveSets and have basically got back to where I was +10% which is OK. Now here is something interesting I do not understand completely 1) I turned on display lists ( with VBO off), and the speed of rendering went up enormously - but with a memory penalty of course. From probably 2-5 frames per second to 30 frames per second+ for a model of 1.5 million elements. 2) Turning on VBO ( with display lists off) did not seem to do anything. Certainly the rendering speed was not improved noticeably.

It's a pretty easy job. You basically put in a request for a BOF room. Last year I think we had 60 people, but we've had as many as 110+ in the past, so I'd suggest reserving a room for 120. Then you post here to line up speakers. I'm not sure how SIGGRAPH is handling A/V this year, but I'm sure they'll provide some kind of solution. Mike and I would be happy to answer any questions. -- Paul Martz Skew Matrix Software LLC _http://www.skew-matrix.com_ http://www.skew-matrix.com/ +1 303 859 9466 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] OpenGL ES-2.0, OpenGL ES-1.1 and OpenGL 3.x support now ready for testing :-)
Hi Robert -- Thanks for the update. Here's my additional comments for GL3. The basic stuff is there provided the app takes the responsibility to make their scene graph GL3-safe. Win32 context creation works, but X11 is TBD as you noted, so if any Linux people would like to step up and do GLX GL3 context creation, that'd be great. I'm not sure what to do about OS X (as my Mac doesn't support GL3 so I have no way to test any code that I might write, plus I'm not sure which interface supports GL3: AGL? Cocoa? NSOpenGL?) Still plenty of non-critical GL3 work to be done. One major enhancement will be modifying vertex attributes to allow specifying an attribute name rather than a slot number. I've got this on my calendar for first half of next year. -Paul Robert Osfield wrote: Hi All, Over the past week I've had my head down beavering away on porting the OpenSceneGraph across to work on OpenGL ES 2.0, this bulk of this work is now complete and checked into svn/trunk.

For instance I now know that the OSG is compiling under QNX with OpenGL ES, but alas we don't yet have any CMake build support in place, also now we support OpenGL ES it should be possible to provide a port to the iPhone/iTouch and other embedded platforms. Support for creating graphics GL3 contexts under GLX isn't yet done as well. I don't have the hardware/SDK to try out all these different targets, but this is why the OSG community has been historically very strong - almost all out platform ports have been done by members of the community. If you have the itch in any of these areas please chip into this thread and we can coordinate out efforts. Another side of my finally being able wrap up the OpenGL ES ports is that I'll finally have much more scope for catching up with osg-submissions, and start getting dev releases out the door and work towards getting the next stable release out. There should also be more opportunities for me to chase up on various outstanding design/implementation issues. Please be patient though, I can't suddenly tackle everything at once - my first priority is getting up to date with submissions and a dev release out the door, and tidying up the new OpenGL ES ports.

[osg-users] Updates to osgBullet
Hi all -- I have updated the osgBullet project to include an example that demonstrates running the physics simulation in a separate thread concurrently with the OSG rendering. The source repo is here: http://osgbullet.vesuite.org The example is in examples/multithreaded. -- Paul Martz Skew Matrix Software LLC _http://www.skew-matrix.com_ http://www.skew-matrix.com/ +1 303 859 9466 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] setNumChildrenRequiringUpdateTraversal
Folks, Is it legal to call setNumChildrenRequiringUpdateTraversal() during the CULL traversal? I ask because I'm getting a very hard-to-replicate crash in that method and I'm trying to eliminate possibilities. Thanks.

Re: [osg-users] setNumChildrenRequiringUpdateTraversal
Cull can be multithreaded in osgViewer apps. Do you know which threading model you're using? Try SingleThreaded and see if the problem goes away. -Paul Glenn Waldron wrote: Folks, Is it legal to call setNumChildrenRequiringUpdateTraversal() during the CULL traversal?

Hi Robert, thanks for all the good news. Just a heads up... There's been some es-2.0 goings on in Mesa as well. Some clippings from mesa3d-dev: ---8--- From: Chia-I Wu Subject: [Mesa3d-dev] [PATCH 0/6] Make opengl-es-v2 branch work Date: Fri, 6 Nov 2009 18:11:15 +0800 Hi, This patch series is against opengl-es-v2 branch With this patch series, one may $ make linux-opengl-es $ make install in the top directory of mesa. It will install EGL, an EGL driver, and OpenGL ES state trackers. There are some demos for OpenGL ES that can be found in progs/es1/xegl/ and progs/es2/xegl/. ---8--- From: Chia-I Wu Hi list, I am working on a project to bring Mesa to Android on x86 (intel) netbooks http://www.gitorious.org/android-eeepc ---8--- From: Daniel Stone Subject: Re: [Mesa3d-dev] Android support Hi, On Tue, Nov 10, 2009 at 03:21:35PM -0700, tom fogal wrote: We've got an app we'd like to port to `another' mobile platform, but shaders are a sine qua non for us.

Re: [osg-users] [osgOcean] osgOcean also rendering with osgParticle?
Hi Kim: Have you solved the particle render problem in OsgOcean1.01? Could I open the glare and DOF effects with fire particle effect? Cheers, MT Kim Bale wrote: Haha well I've never played with them so I was rather sketchy on the theory. Using MRTs would actually make for a pretty easy fix. I shall see if I can do that this week. K. 2009/11/16 Jean-Sébastien Guay : Hi Kim, I'm not sure if Ogls multiple render target implementation is any more efficient than using a completely separate pass but rendering the ocean twice would be very costly. Yes, of course MRT is more efficient than multiple passes... It's only one pass of the geometry, but with multiple buffer attachments that you can address independently in your shaders. That's the whole point of MRT :-) J-S -- __ Jean-Sebastien Guay http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- Post generated by Mail2Forum -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=19769#19769 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
