Re: [osg-users] Mask projective texture
Hi Mateo, I'm a bit confused as to what you are actually doing, my best guess is that it's something like shadow mapping. The best place to start is to have a look at the osgprerender example and others similar to it. Have a look at all examples that use osg::Camera when doing render to texture, also have a look at the osgShadow library as it's osg::Camera usage will show how to set up the Camera to create a render to depth texture.

Hi Rishabh, The ref_ptr is smart pointer that will automatically manage the ref and unref of OSG objects, and when the ref() count of these objects goes to 0 they will be automatically deleted.

Hi Peterakos, The bulk of the OSG loaders assume that world coordinates have +ve Z upwards, +ve Y north and +ve X to the east. The majority Camera Manipulators assume the world has Z up as well, then set up Camera's view matrix so the Z up aligns with vertical access of the screen, +ve Y into screen and +ve X to right. You can change the default viewing position in the camera manipulators if you wish by use the setHomePosition(..) method, or avoid the use of Camera manipulators and just set the viewer's Camera's view matrix directly using any of the Camera::setUpView*() method.

It's easiest to reproduce if you try to compress rectangular texture with width height using DXT compression. Last mipmaps with height 4 will get corrupted and some mipmaps may be lost because of computed size different from the actual one. Use osgconv --compressed -O OutputTextureFiles test01.ive out.osg on attached sample to create corrupted .dds file. Problem was introduced with change # 12912 from January I think and comes from not taking block nature of DXT compression into account in computeImageSizeInBytes function. computeRowWidthInBytes computes average row size for DXT correctly but later there's no code to clamp height to 4 in computeImageSizeInBytes for rectangular DXT textures (I think computeBlockSize works as clamp for square ones so error is not present in such case). Perhaps other texture formats are affected too but I tested only DXT so far. I'll try to prepare fix but not before January 2nd.

Re: [osg-users] Custom culling that works with shaders
Hi Glenn, Just a quick reply as I'm just back from holiday season and rather cold on techy topics. Currently the OSG's culling is based around testing a internal nodes bounding sphere against the view frustum polytope and the geometry leaves bounding boxes. With shaders having the ability to move geometry around it obvious introduces a where is it now? issue for any of the present bounding volume code that tries to handle geometry with such shaders. Currently the OSG has an osg::Drawable::setInitialBound(..) feature but this is really crappy and has long deserved a complete overhaul in the face of widespread usage of shaders. I don't believe tackling this issue by just providing some for of culling callback/control would be sufficient as it's not only culling traversals that need to test the whereabouts of geometry in the scene graph. What exactly a general purpose solution might be I can't say without putting some more time thinking about the topic. A good first step would be to improve the bounding box controls in osg::Drawable so it's better at managing user set bounding volumes. Robert. On 4 January 2013 15:44, Glenn Waldron gwald...@gmail.com wrote: Robert et al., The topic of culling vis-a-vis shaders has come up a few times recently. The issue is: if you transform or emit vertices in a vertex, geometry, or tessellation shader, the new position information is not available to OSG's culling mechanism. This may result in visible geometry being culled. One approach is to artificially inflate the bounds of your geometry. Not very elegant. Cull callbacks won't help, since the visibility logic is in CullStack::isCulled() which executes before any cull callbacks. What I would like to do is use a custom frustum for culling. In my app I have just such a frustum, and I tried applying it the the current osg::CullingSet; but that CullingSet is automatically kept in sync with the Camera frustum and my changes get overwritten. I think we need a general-purpose solution, since this topic is bound to come up again. Here are a couple ideas: 1) Allow the user to customize CullStack::isCulled() in some way, either with a callback, or by making the isCulled() variants virtual. 2) Allow the user to apply a custom visibility frustum to the osg::CullingSet. (Calling CullingSet::setFrustum works, but gets automatically overwritten when there are subsequent Transforms in the scene graph.) I look forward to your thoughts.

Does any of this seem incorrect?
Lastly, when I go to build this project in Visual Studio it builds everything
successfully except for the cudakernel project which has more than 100 errors.
I'll post some of them here (there are many more of the C2719 errors but I
think you'll get the point):

Re: [osg-users] Happy New Year.
Well, my New Years resolution of publishing more stuff so far has fallen flat on its face. :( I have a whitepaper detailing how (I think) VPB/OSG/PagedLOD structures, build and uses data which I think many people would find useful, but I haven't polished it up and published it yet. Soon... Also, I'm still getting client releases and materials to talk about some of the other nifty projects we've done over the last year or two. And we have some more pre-compiled binaries to release, but I need to structure the web site to present them... And my cloning project has yet to produce a carbon copy of me to do all this drudge work while I code, or sip cold Macallan somewhere warm and tropical. BTW, that house in Skyfall was yours right? Pity about it gettin' blowed up an' all. ;) On Mon, Jan 7, 2013 at 6:31 AM, Robert Osfield robert.osfi...@gmail.comwrote: On 1 January 2013 19:48, Chris Hanson xe...@alphapixel.com wrote: I'm sure everyone, like myself is recovering, and playing, and spending non-work time, but I wanted to give a shout-out to everyone for a great and prosperous 2013.

We're working on updating our builds as well, which will include the COLLADA loader, if we can ever get it to compile. ;) On Sun, Jan 6, 2013 at 6:49 AM, Mohamed Alji osgfo...@tevs.eu wrote: ** Excellent Philip your solution worked ! -- Mohamed ALJI Blog http://aljilogy.blogspot.fr -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=51799#51799 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Training • Consulting • Contracting 3D • Scene Graphs (Open Scene Graph/OSG) • OpenGL 2 • OpenGL 3 • OpenGL 4 • GLSL • OpenGL ES 1 • OpenGL ES 2 • OpenCL Digital Imaging • GIS • GPS • Telemetry • Cryptography • Digital Audio • LIDAR • Kinect • Embedded • Mobile • iPhone/iPad/iOS • Android @alphapixel https://twitter.com/alphapixel facebook.com/alphapixel (775) 623-PIXL [7495] ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Building OSG/Producer/OT 1.2 w/gcc 4.4.5
Hi, I find myself in need of building OSG/Producer/OT 1.2 to support a legacy project. I am using gcc 4.4.5. I am getting numerous compile errors regarding undeclared functions such as memset, memcpy, getenv and so on. These seem easy enough to correct by adding the proper includes to the .cpp files in which the errors are found, but before I continue to do so, I thought I should ask if this was the correct or best approach and if I should expect any issues downstream in doing this or in general with building OSG/Producer/OT with 1.2 w/gcc 4.4.5. CD ... Thank you!

Hi, Conan, I vaguely recall having all kinds of problems with OSG 1.2 compiling with any version of gcc4. I think we ran into this when we upgraded our version of Red Hat in the lab, and the new version switched from gcc3 to 4. Our solution at the time was to go ahead and upgrade to OSG 2.0. The point being, there probably isn't a right way to do this. Whatever works best for you is probably the right way. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Which GPGPU postprocessing method is best for me?
Hi Ethan, You may found the osgeffectcompositor in osgRecipes project as Jeremy says. I'm currently working on a better version of ViewDependentShadowMap and will try to provide a complete pipeline using forward shadows and deferred shading work. It is always appreciated if you and others could provide some more ideas and suggestions. :-) Wang Rui 2013/1/8 Ethan Fahy ethanf...@gmail.com Thank you Jeremy I'll have a look at that implementation (I was actually just reading through Rui Wang's cookbook when you posted this). In the meantime I'll also try compiling osgPPU and osgCompute and go through some examples to assess which of these can accomplish what I am looking to do. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=51827#51827 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Can OSG be used as a tool to edit maps?
My question is as an offset to a discovery that osgEarth does not allow saving a map it generates, to the hard disk. So I was wondering that if osgEarth is only for displaying maps, and virtual planet builder was to split up a map into tiles and lod's, and osgEdit was meant only for minor modelling of a scene, then that leaves me with only OSG itself, which has to be programmed in such a way that it allows me to edit a scene the way I want to edit it. Eg.If I have a vector map (in whatever format) and I want to change a few details (like the color of a few lines) in it and save the map (as .osg or .ive or any other format), is my only option to use OSG for this task? What is the best way to edit maps using osg related tools? I'm ready to do some amount of programming related to it, as long as I can customize it as per the intricate details I want to edit. Raster, vector and maybe even DEM. Nav of Joseph? You can call me Nav :-) -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=51835#51835 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
