Re: [osg-users] Objects with (very) high mesh resolution not showing up in viewer?
Hi Preet, 48 rings and 72 This isn't a particular big mesh at all - the osgparametric example creates a 708x708 mesh for roughly 1 million triangles, it runs at a solid 60Hz on even my 8 year old laptop, so we can safely say that size of the mesh is not a problem. You'd have to have a pretty crappy graphics card and drivers not to be able scale up. What is the hardware?? The OSG viewer will automatically assign a TrackballManipulator when you call viewer.run() and this will set it's home position to the center of your model. As for the coordinates - it's certainly not ideal to use ECEF coords with floats, but all that should happen is you'll get a bit of jitter on the coordinate position. There are ways of solving this - a topic that has been discussed many times before here so just look in the archives for discussion about whole earth databases. Robert.

I just found out about the OSG_NOTIFY_LEVEL env var, and I get a bunch of messages about the viewer's drawing traversal: cull_draw() 0x988f788 _clampProjectionMatrix not applied, invalid depth range, znear = 3.40282e+38 zfar = -3.40282e+38 end cull_draw() 0x988f788 I'm using large scaled units (ie, millions) in the scene. Maybe the geometry isn't within the camera's frustum, or something like that? I don't get why change the number of vertices that make up the geometry would cause a change like that though. I construct a spheroid using arguments for parameters that correspond to latitude / longitude style divisions. The latitude argument defines how many 'rings' go down one axis of the sphere, and the longitude argument defines how many 'sectors' each 'ring' is divided into. So if I specify 36 rings and 72 sectors for each ring, I expect my sphere to have (36*72) vertices. This works fine. If I up the ante to 48 rings and 72 sectors, osgViewer won't show the geometry. The function I call isn't doing anything special... and seems to complete fine before being sent to the viewer. http://pastie.org/3497231 - line 184 is where I defined the function.

I wrote a function which calculated vertices, normals, texture coords and indices for the geometry. The function takes the number of 'sectors' and 'rings' as arguments to generate spherical geometry. It works fine until I hit some limit as I increase the resolution of the mesh (by passing a larger number of sectors and rings to the function), after which point osgviewer doesn't display the data. There aren't any errors; the geometry just doesn't show up in the viewer. If I go back beyond some threshold the geometry shows up again. What's going on?

Re: [osg-users] OSG using OpenGL 3.2 in Mac OS X 10.7 (Lion)
HI David,
The OSG is designed to check for extensions at runtime, so even if you
compile the OSG against OpenGL 1.1 it will still be able to load up
OpenGL 3.2 features at runtime and use them.
The CMake option to compile specifically against OpenGL 3 is for when
you want to compile against OpenGL 3 without the backwards
compatibility to OpenGL 2.x, this disables all the fixed function
pipeline. This is something you might want, but it's mostly not
necessary.
Robert.

Hi,
I'm trying to compile an application in Mac that requires OpenGL 3.2. The

/usr/bin/cmake -G Xcode -D OSG_COMPILE_FRAMEWORKS:BOOL=1 -D

OSG_GL2_AVAILABLE::BOOL=0 .
And seems that this time uses GL3 as it fails to compile with the error:

Re: [osg-users] Possible memory growth issue with sorted Particles
Hi Frank, I haven't used the sort feature personally and would suspect not many others have as well as I'm sure they'd have spotted the same problem as you. I must admit that all the recent particle work I've done has been with shaders rather than the CPU based particle systems that the bulk of osgParticle deals with, in the longer term I'd like to replace the osgParticle code base with a shader based approach. Short term fixing the problem you have in front of you is what will be required. I haven't looked into the problem yet but off the top of my head I would wonder if perhaps the sort could take whether the particle is dead when taking it into account, or have the dead particle tracking updated. Robert. On 2 March 2012 02:18, Frank Sullivan knarf.navil...@gmail.com wrote: Greetings, I am having some difficulty with the osgParticle classes, and I was wondering if someone could give me some advice. It seems that whenever I choose a sorting mode for the particles other than NO_SORT, I get a particle list that grows unbounded. In a normal situation, the particle list should grow at first, and then stabilize as dead particles get reused. So, for example, if I set the particle effect to emit at a rate of 100 particles per second, and I give the particles a lifetime at 1 second, then over the course of the first second, I should see the particle list grow from 0 to 100. At that point, particles should start dying at about the same rate as they are being created, and so the list should stabilize at 100-105 (allowing some buffer because the world isn't perfect). And indeed, this is exactly what I see when the particles aren't sorted (I created a DebugParticleSystem subclass that prints out the particle list counts, and other info, each frame). However, when I set the sorting mode to SORT_FRONT_TO_BACK, then I get this weird behavior where the particle list grows and grows and grows and never stabilizes. Looking at the code, I think I have a hypothesis, but it isn't complete. Basically, after the particle list is updated, the list then gets sorted. This is an in-place sort on a vector of Particle objects, which has the effect (from what I can see) of invalidating the pointers in the _deadParts stack. So, the pointers in the _deadParts stack end up pointing to particles that are still living, and when a pointer from this stack is used to reuse a dead particle, it ends up reusing a particle that is already alive. Now, I'm not exactly sure how this results in a growing particle stack, but my guess is that, in reusing a particle that is already alive, you prevent it from dying on schedule, and so when it comes time to create a new particle, there aren't enough dead ones on the stack to reuse, and so new particles have to be created from scratch. The only thing that gives me pause about this explanation is that, after a Google search, I was not able to find anyone else who is having this same problem. So, I am pretty sure that I'm doing something wrong here, but I'm not sure what. Thank you!

Re: [osg-users] live video texture performance
Hi Michael, On 2 March 2012 02:41, Michael Schanne michael.scha...@gmail.com wrote: Using a PixelBufferObject did not appear to make any difference in performance for me. My video hardware only supports OpenGL 1.5, so that is probably the reason. What hardware is this? It must be off towards a decade old, or a decade out of date. I suspect the power of two issue is the cause of my performance problem. When I create a 640x480 image I get a console message that it is being scaled to 512x512. However, when I try to create a 512x512 image instead, I get an error message Detected OpenGL error 'invalid enumerant' at After Renderer::compile. This is before I even attempt to load any video data into the image. What does this error mean? There is too little to go on to know what caused the OpenGL error report. There are two routes you could take avoid the resize issue - use TextureRectangle if supported by your hardware or set the size to 1020x512 and only use a portion of the image. Using 640x480 (which gets scaled to 512x512) I get a white quad, as I expect. If it rescales for you you should still get a valid image, not a white quad, so something is wrong here. What I can't say, but the OSG has been doing the automatic rescale since it's earliest days without any problems being reported like this so the fact you are getting a white quad suggests something else is going wrong on your system to cause this problem. I would suspect a OpenGL driver bug. However, if I use 512x512 image, I see distorted green lines with a black background on the quad, along with the error. If I try to load any video data at this point, the program crashes. I would suspect a memory corruption issue with a crash, or just a downright buggy OpenGL driver. Is there a chance that your video is being read at 640x480 and you are writing this to the 512x512 image without cropping it? I also have the option of using a video frame of 8 bits per pixel (for a greyscale image) but I have not been able to see the image at all in that case. I tried using the GL_LUMINANCE pixel format and GL_UNSIGNED_BYTE data type, along with a few other combinations, but nothing has worked so far. I think perhaps you need to take a step back and doing some more general tests on your system to see what it's capable of. Please could you tell what OS, dev tools, OSG version, CPU + graphics hardware you are working with.

Hi James,
Looks like it's an easy one to answer, so I will give it a go:
It looks like the path to OSG is not set correctly or it doesn’t know
where to find your include/lib files.
The paths to OSG will need to added to your development environment, not
sure what you are using.
Regards
Martin

Re: [osg-users] Possible memory growth issue with sorted Particles
Thanks Robert, It looks like, when the particles are sorted, dead particles are given a depth of 0 so that they are automatically placed at the beginning of the list. This will be useful, I think, because it looks like the purpose of the _deadparts stack is to keep track of which particles are dead, so that when the ParticleSystem wants to reuse a dead particle, it doesn't have to do a linear search through the particle list to find them. However, if I know that the dead particles (if any) are at the beginning of the list, then I can just take a look at the first item on the list. If it's dead, resurrect it. Otherwise, create a new one. So I might try subclassing ParticleSystem and overriding the CreateParticle method. In it, I'll check the sorting mode. If it's NO_SORT, then I'll use the _deadparts stack as usual. Otherwise, I'll just check the first particle in the list to see if it's dead. I won't have a chance to try this for a few hours because I have to run off to school, but I will let everyone know how it works out.

Re: [osg-users] Performance question: Switch / NodeMask / WriteToFile
Hi Hartmut, Using 100's of thousands of scene graph objects to represent a tree will always be a performance problem, no matter what LOD'ing or scene graph structure you use. Using such a fine grained scene graph will cause problems in cull, draw dispatch and draw down of the GPU. It very much sounds like you have engineered one of the worst possible ways to tackle the task one could think of. This really begs the question what you are trying to do here? When you say a tree, could you give us a screen shot so we know what you are trying to achieve. Perhaps if we know what you are trying to achieve we can recommend how you should construct your scene graph to achieve best performance. Robert.

Re: [osg-users] 3D Frame Packing with OSG
Hi, I've found a solution to using the Sony HMZT1 with OSG and a Quadro FX 3800. It basically comes down to setting the following as per the Quad Buffered 3D Stereo instructions in C:\NVIDIA\DisplayDriver\driver version\your OS\International\NV3DVision\nvst3.chm which say: To enable quad-buffered professional stereo: From the NVIDIA Control Panel navigation tree pane, under 3D Settings, select Manage 3D Settings to open the associated page. Click the Global Settings tab. From the Settings box, click Stereo-Display mode and then select the appropriate option, depending on your stereo hardware. From the Settings box, click Stereo-Enable and then select On. Click Apply. From the NVIDIA Control Panel navigation tree pane, under Stereoscopic 3D, select Set up stereoscopic 3D to open the associated page. Make sure the Enable stereoscopic 3D check box is cleared, then click Apply. Sterescopic diplay type: should indicate Quadro professional stereo. It may be necessary to make the HMZT1 the primary display. Then use: Code: osg::GraphicsContext::WindowingSystemInterface* wsi = osg::GraphicsContext::getWindowingSystemInterface(); wsi-setScreenResolution(osg::GraphicsContext::ScreenIdentifier(screenNum), 1280, 720); or similar to setup the correct resolution. Try testing with the osgViewer using the QUAD_BUFFER command line option and cow.osg and... ...Hello 3D Daisy! Now on to integrating with our actual software. I would be curious if anyone figures out a way to make the HMZ T1 work with GeForce cards and OSG as my laptop doesn't have a Quadro.

Re: [osg-users] osgexport - new version
Hi Cedric, Thank you all for this new version. May I ask you with which Blender version did you use for this version ? I am sorry if I bother you about this problem, but this OSGExporter doesn’t work very well for me (I worked with Blender 2.59.0 r39307 (release version of 2.59) as well as with 2.61.0 r42615, Windows 7-32 bits) and the results are the same. I explain: for the avatar example (in the avatar directory on the osgexporter website), I got an osg model with black rectangles around the eyes, the mouth, etc. at the same place as of the spheres used to put the eyes, mouth. I also created 3D models with Makehuman, and no more success: I tried with naked and dressed characters but both failed. For the dressed character, I just got the skirt and a weird box … Please, may I ask you to have a look at my blend files and see what wrong am I doing ? Thank you very much.

Re: [osg-users] Help compiling example program
Hi, Sorry guys, I know you're probably explaining things perfectly clearly and it's just me. But this is all jargon to me. Martin Naylor: That link is a guide to building what under Unices? OSG, or applications that use it? I installed using apt; this means I can skip the part about dependencies right? This link doesn't say what each of these steps is doing and why one would need it. I'm sure it's obvious you most of you, but my mind wasn't wired for this kind of stuff. Also, this guide is about make, not g++. I ran Code: # dpkg -L openscenegraph and my output was a bunch of stuff in the /usr/bin/ directory, a bunch of stuff in the /usr/share/man/man1 directory, and some stuff in the /usr/share/openscenegraph/ directory. Doing Code: ls /usr/lib | grep osg or Code: ls /usr/lib64 | grep osg or Code: ls /usr/include/ | grep osg yields nothing. Again, I installed OSG from using apt-get. Please help. I don't know exactly what I'm asking for because I don't know exacctly what I need at this point. Thanks for your patience. Thank you!

Good work! The problem looks like you may be using the default texture wrap mode, which is CLAMP. This mode can also be called clamp to border, which when texture coordinates run outside the range of 0-1 will give a border color, which defaults to black. The problem is that when the texture coordinates are exactly 0 or 1, when you have linear interpolation enabled as filter mode (again the default), then the border color will still get sampled (since it's trying to filter using that texel and the one next to it, which is outside the 0-1 range). So you get those black lines around your textures. Try to specify the CLAMP_TO_EDGE wrap mode instead. This will simply sample the same texel at the border and should eliminate the black line.
