[osg-users] osgText and Texture
Hi, I created a texture and set to a camera. Another camera was set to a text. Text and the texture are in different views. Always the text goes behind the texture. What needs to be done to make the text appear always in front? I tried by setting the texture state's rendering hint as TRANSPARENT. But couldn 't any change. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=26342#26342 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] View-dependent OverlayNode w/o CoordinateSystemNode?
Hi Chris, Chris Long wrote: Hi, Thanks a lot for the quick reply. Yes, that's definitely an improvement. The demos now work better. VIEW_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY looks good. But with VIEW_DEPENDENT_WITH_PERSPECTIVE_OVERLAY, the geometry that the overlay is pasted onto still turns all black in the osganimate and osgspheresegment demos. Changing the zfar doesn't seem to matter; using getPoints instead of computeSilhouette is what does it. Unfortunately, it doesn't solve my underlying problem (yet), which is needing to overlay geometry that's far apart. When I run my app with this modification, the overlaid geometry shows up in view-dependent mode (yay!), but it's still rendering all the overlaid geometry so the quality of the overlaid texture degrades as the bounding box of the overlayid geometry increases (boo!). I tried it both with perspective and orthographic rendering. I'm thinking now that maybe if I look more into computeSilhouette I might be able to get it to do what I want. But if you (or someone else) has any ideas about it or about other approaches, I'd love to hear it. Only other advice I have is to look at this discussion and patch: http://thread.gmane.org/gmane.comp.graphics.openscenegraph.cvs/4260 I'm not sure if this was ever integrated. I've not had success with VIEW_DEPENDENT_WITH_PERSPECTIVE_OVERLAY either, I also encounter some strange cases from some viewing angles, but I've just never had the time to investigate further... rgds jp Thank you!

[osg-users] Callback to run existing OpenGL Code
I'm moving my backend to OSG, but I'm too chicken to do it all at once. Where would be the best place to run existing code? The code is a set of texture transfers (individual planes of videos) and then some drawing with a shader to convert it to floating point RGB. The transfer code should: run every single frame, before other operations (resulting textures get used), should ideally be split - transfer starts (PBOs) and transfer completion, could optionally use a pre-process camera and osg::uniforms, Can be overlapped with existing rendering (the tail of the previous drawing) - first phase won't affect textures in use. Should be done once per GPU (assuming contexts are shared on each card). Is there a callback or two that would fit? Is it kosher to do the work in a draw callback, or is there an earlier point that is in the OpenGL context? Maybe an example? Since I know the 'best advice' will probably be to bite the bullet, as a sanity check, I mention that my code is an ffmpeg video channel that decodes the video into native planes, then transfers multiple planes and uses a shader and multiple texturing to convert to floating point and do various color correction etc. I think fitting that into the existing ImageSequence, which seems to assume single frames of RGB, would be too time consuming at the moment.

You can also use part of the nodemask You only need the top bit for the culling, you can use the rest for any id number you want. The advantage of this is also that the nodemask is saved in the osg file without you having to make any modifications - assuming your id is valid across loads.

Re: [osg-users] looking for a terrain database building
Hi Torben, It's good to see I'm not the only one trying to do this stuff. Yes, coming up with a toolchain document that tells people specifically how to string together a lot of different tools would be good. I was just playing with osgEarth yesterday, and damn! that's neat. I haven't had as much luck getting VirtualPlanetBuilder to understand my geotiffs. But if osgEarth can understand them, then it's probably a solvable problem with how data is getting sent to gdal or something like that. Anyway, I keep coming back to that same problem: I need to be able to manually edit anything with a modeling problem since my employers make random requests all the time. Your flattening of the database in configurable areas sounds similar. So, to answer your question, I'd like to be able to modify databases offline. Being able to do fancy stuff like stitching in roads and prebuilt models of cities and stuff would be very cool. Both VPB and osgEarth seem to default to building scenegraphs with PagedLOD nodes, which I don't think will work for me. One option I thought of is to use VPB to create a big database in a single file with traditional LOD nodes, then use a separate program to convert it all to individual .flt tiles and a Metaflight file or something similar. I'll have to do more thinking about this option. Anyone know of any alternatives to Metaflight that can describe tiled databases but still let you store and edit tiles individually? I just want to consider all the options. -- Terry Welsh / mogumbo 'at' gmail.com www.reallyslick.com / www.mogumbo.com > > Message: 14 > Date: Tue, 30 Mar 2010 10:33:34 + > From: "Torben Dannhauer" > To: osg-users@lists.openscenegraph.org > Subject: Re: [osg-users] looking for a terrain database building > toolchain > Message-ID: <1269945214.m2f.26...@forum.openscenegraph.org> > Content-Type: text/plain; charset=UTF-8 > > Hi Terry, > > I have quite the same goal to reach, so I would happy to cooperate and create > a usefull toolchain. > > At the moment I use VPB to generate the database. > I'have tried osgEarth but the VPB Plugin over there doesn't work very well, > it loades all tiles at highest LOD and my FPS falls down to less than 5 fps. > So osgEarth is not an option. > > At the beginning, I had a lot of problems to compile my datase ( ~800GB raw > data. > with 64 Bit and the newest VPB it now works quite stable, resuming works and > it is possible.

[osg-users] 2.8.3rc2 Mac Xcode project - Windowing system
On the Mac Xcode project, the Cocoa viewer works, but on the osgviewer and osgmovie targets, they don't run. I've tried the Carbon 32-bit and Cocoa 32-bit versions. I linked to Carbon, Cocoa, OpenGl and Quicktime Frameworks. osgViewer, OpenThreads, osg, osgDB, osgText, osgUtil, osgGA Frameworks are copied into the bundle's Frameworks folder All plugins are copied into the bundle's Plugins folder But when the apps try to make a window, they fail with: View::setUpViewAcrossAllScreens() : Error, no WindowSystemInterface available, cannot create windows. As I recall, this used to be enough. Did the introduction of the Cocoa viewer change something? Is there an environment variable that needs to be set? Since I intend to make a Mac bundle, I'd rather not have any user installation steps.

Normally a 2.8.x series should be bug fix release, with binary compatibility where possible. Bumps in the minor point i.e. 2.8 to 2.10 would imply new features, and allow for binary incompatible changes. For the 2.8.3 release it's been mostly about bug fixes, but alas it has broken the binary compatibility, and there is a few feature enhancements as well... so... it's pushing the normal boundaries of a patch release, but it is enough to justify a bump in the minor point to 2.10? This is a good question. Right now 2.8.3 has been made off the 2.8 branch, so if we did change 2.8.3 to 2.10.0 then we'd need to make a OpenSceneGraph-2.10 branch, then update the version info, then make a 2.10.0-rc1 off 2.8.3. This is a bit more work for Paul who will already been rather pushing things, I could do the branch if Paul wants to go this route. I'd also have to bump up the 2.9.x dev series to become a 2.10.x dev series to avoid confusion over features, this is a minor change for me though. Marketing wise a 2.10.0 release sounds more impressive than a 2.8.3 release... I'm easily swayed either way.

Re: [osg-users] [osgPPU] Help with glow example
Hi Allen, just for the next, if you have questions regarding to osgPPU, then take first a look into the documentation. osgPPU project can be found at http://projects.tevs.eu/osgppu the doxygen documentation is at http://www.tevs.eu/doc/osgPPU/ osgPPU is pretty well documented or at least comment in the code. I tried to write a lot of comments for beginners, so take a look on them. Now to your questions: allensaucier wrote: > > 1. what line of code actually performs the glow effect? > a.

For glow effect the object which has to glow is rendered separatly in a buffer. This buffer is then blurred (shaders) and added to the main view also in a shader.

Think on the osgPPU pipeline as on some graph with nodes as your processing units, which do something with the input and producing the output to the next nodes. Processor is the root node of the pipeline and has to be always used. It is needed to allow running of osgPPU's own node visitors to be able to flawlessly cooperate with OpenSceneGraph. > > 4.

As I said before, every unit is a node computing outputs by using inputs. Inputs are always textures. So in order to bring it to the pipeline from OpenSceneGraph's cameras, we place this unit either directly under Processor or under UnitCamera. UnitCamera do bypass the osg's camera to the pipeline. It has no direct output and hence UnitCameraAttachmentBypass is required to get camera attachments and put it into the pipeline. Units placed under AttachmentBypass will use camera's texture as input. So, I hope I was able to clarify this. Please take a look into documentation. Based on the examples and the reference api documentation (doxygen) you should be able to understand what is every unit good for. regards, art -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=26311#26311 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Anders,
All the ..'s are intended and put there with the purpose to avoid the
Release, Debug, RelWithDebugInfo and RelMinSize folders that Cmake
wants to put binaries (and other stuff like libs) in. You should look
in the other end - that is - why your cmake install script doesn't

but this scheme has been there since then I think. I haven't got

[osg-users] ffmpeg plugin on osx

I even tried setting the flags like this without much luck. LDFLAGS="-arch i386" CFLAGS="-isysroot /Developer/SDKs/MacOSX10.5.sdk -arch i386" Any ideas. Hope this is not too offtopic here.

Hi Community, I have several questions about the glow example. Any help would be appreciated. 1. what line of code actually performs the glow effect? a. I am a novice with shaders and osgPPU b. I found how to increase the intensity of the glow within the shader source code; it is the * 2 effect on glowColor c. I can not find the line of code that actually performs the glow 2. Within the shader source code, the variables view and glow confuse me. Nothing within glow.cpp refers directly to either of these variables and so I do not know 1) how the glow effect actually happens. 2) how the different input to shaderSrc is actually differentiated between view and glow. Would someone please tell me? :-* I have noticed that the resultShader receives input from unitCam1 and from blury which gives the "view" and "glow" outputs, though I do not fully understand how. 3. I have continued to notice the use of processor as the beginning of the pipeline. When adding a child to a pipeline element, does that automatically send output to the child? 4. I have noticed that there are 2 camera inputs into the pipeline. One is the main camera directly attached to processor. The other is a new camera, slaveCamera, which is attached to unitSlaveCamera. What stops the main camera's output from going into the unitSlaveCamera? 5. what does osgPPU::UnitCameraAttachmentBypass mean? 6. what does osgPPU::UnitCamera mean?

If the code is C++ then I would be inclined towards using unique namespaces for the different plugins. Some already do this. If the the code is C or pulled into from an external project like lib3ds then use of namespaces is problematic so making sure names are unique would be appropriate. static linking itself is something that we probably need to expand out tests for - the osgstaticviewer is the only example designed for static linking, and it only links with a couple of plugins.

Re: [osg-users] View-dependent OverlayNode w/o CoordinateSystemNode?
Hi, Thanks a lot for the quick reply. Yes, that's definitely an improvement. The demos now work better. VIEW_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY looks good. But with VIEW_DEPENDENT_WITH_PERSPECTIVE_OVERLAY, the geometry that the overlay is pasted onto still turns all black in the osganimate and osgspheresegment demos. Changing the zfar doesn't seem to matter; using getPoints instead of computeSilhouette is what does it. Unfortunately, it doesn't solve my underlying problem (yet), which is needing to overlay geometry that's far apart. When I run my app with this modification, the overlaid geometry shows up in view-dependent mode (yay!), but it's still rendering all the overlaid geometry so the quality of the overlaid texture degrades as the bounding box of the overlayid geometry increases (boo!). I tried it both with perspective and orthographic rendering. I'm thinking now that maybe if I look more into computeSilhouette I might be able to get it to do what I want. But if you (or someone else) has any ideas about it or about other approaches, I'd love to hear it. Thank you!

[osg-users] duplicate symbols in 3DS and OBJ plugins
Hi all -- Stefan uncovered an issue when building 2.8.3 with static libraries. The OBJ and 3DS plugins have duplicate symbol names, notably PrimitiveIndexWriter::drawArrays, which causes a link error. The FBX plugin might also have this issue. See the thread "2.8.3-rc2 tagged" for full details. I wanted to open a new discussion thread for this issue, as it's almost certainly a problem on trunk and therefore applicable to anyone in the community building OSG as static libraries. Any fix I put in to 2.8.3 will probably need to be merged back to trunk. One way to resolve this would be to wrap the symbols in a plugin-specific namespace. Alternatively, we could hit it with a hammer and just change the symbol names so that they are unique across all plugins. Does anyone have any other thoughts or ideas on this? Seems like we need a policy that we can use in OSG going forward, so that this same issue doesn't keep creeping back into the code (only to be discovered the day before the scheduled release :-( ...) -- -Paul Martz Skew Matrix Software http://www.skew-matrix.com/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] How to set an ID to a node?
Bonjour Benjamin, In fact, the only thing I have seen in the doc is the possibility to give the node a name (a String). You can use the name as an ID, it's up to your application to make sure the name is unique (perhaps unique in a particular subgraph). You could use a "name path", something like if a Group called "bob" has a child named "gilles" then the child could be referred uniquely by the name path "bob.gilles" or something like that. But that's all up to your app, OSG provides nothing to help you with this. Hope this helps, 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
Re: [osg-users] 2.8.3 release imminent
Hi Rafa, I'm not sure if we arrive on time, but maybe it will be interesting to add lastest mods of CMake for Collada plugin. What do you think? I had already requested the recent changes to the Collada plugin and Paul said it would be too big a change to include in 2.8.3, given how much is already there, so perhaps in a possible 2.8.4 after that...

Re: [osg-users] looking for a terrain database building toolchain
Hi Torben, I'd recommend using the trunk if you're unsure of what version of osgEarth you're using. Right now it's just up to you to know what version of the source you built against. I'd recommend updating to the trunk if you're unsure what version you've used. I believe that if you use a standard osgdem command line, vpb will create a database that can be accessed via osgEarth using the "nested" directory structure with no split levels. You can define split levels with vpb using the --splits commandline and I believe those are only used with distributed builds. If that's incorrect perhaps Robert can chime in and correct me :) You should also make sure that you add a global-geodetic element within your VPB source as sometimes the computed profile coming from VPB can be slightly off causing osgEarth to try to reproject the imagery, which doesn't currently work with DDS compressed tiles. I haven't seen the issue with osgEarth always loading the highest LOD when using a VPB database, can you elaborate a bit on that?

Re: [osg-users] How to set an ID to a node?

[osg-users] colladas node's name and id issue
Hi, I am using osg to display my kinematics collada models. Kinematics I load myself and osg collada plugin loads the rest. Then I bind kinematics to the osg scene graph. I have noticed that osg collada plugin loads name of the node but not its id. For instance, there is a collada node , corresponding osg node would have a "myName". Is there a way to get the Id, do you read/store it at all? I am asking because names sometimes duplicated and ids are unique. Thank you!

Re: [osg-users] 2.8.3-rc2 tagged
Hi paul, Your description sounds right. And yes the name clash with the fbs plugin was just an assumption after doing a string search in the sources. In terms of wrapping the plugins (eg: 3ds) in a namespace. I am not sure how this would be done without breaking code. I feel like I just know too little how the plugin code gets invoked but I assume that any namespaces have have to be considered there. After all it is an API change. Maybe it's easier than I imagine. Any pointers appreciated. Also feel free to push this to the next release if in a hurry.

Depth into the scene, if an object is on the image plane that the left and right image with be co-incident, if the objects is deeper than this then it'll left image will be to the left and right image to the right, if it's at infinity then the left and right images, for a correctly setup stereo display) should be separated by the interocular distance (the distance between the eyes), if the object is in front of the image plane then the two images will be swapped. In the case of the stats these are just drawn on the image plane, controlled by an override of the projection and view matrix so it is in effect not computed in stereo at all. If the stats did not use their own osg::Camera to override the projection and view matrix then you'd need to carefully position the drawables in depth and orientation to match the position of the image plane in scene.
