Re: [osg-users] Interest in new releases of 2.8.x?
There is one research group at our university waiting for any new official release. They ask me from time to time about it. However, they are not apparently reading mailing list too often as they are busy with their own things. I guess that number of people would welcome the new release if someone would do it. Is there any feature they specifically want in a new release, or are they just wanting the 3.0 stable release? If I remember correctly, it was mostly related to CMake scripts. Probably those responsible for finding the libraries on the disk. These should not be difficult to include in 2.8.4. I sent them email and will be back with the response soon.

Re: [osg-users] Using Vertex Attributes
I can get my square if vertices reside in attribute slot number 0, not 6.
But in this case, my shader needs to be:
Code:
// vertex shader
#version 150
uniform mat4 osg_ModelViewProjectionMatrix;
in vec3 in_vertex;
void main(void)
{
gl_Position = osg_ModelViewProjectionMatrix * gl_Vertex; // gl_Vertex here,
not 'in_vertex'
}
My understanding is that gl_Vertex automatically maps to attribute index 0 with
GL 2.x. What I do not understand, however, is why replacing 'gl_Vertex' with
'in_vertex' does not work - it should do exactly the same.
My aim being to work with a GL3 context, I'm now going to test this code with
OSG_GL3_AVAILABLE. There, I should not be able to use gl_Vertex at all, so I
expect in_vertex to work. If it doesn't, I'll really, really be puzzled.

Re: [osg-users] Alpha blending not working on IOS
Hi Stephan Problem solved, I created a .osg file in 3DS Max with a transparent material and that worked. The only difference I could see between that files stateset and my hud objects stateset was that Lighting was enabled. So I re enabled lighting on my hud object and now the alpha blending is working as expected. Must be some kind of optimisation made by the ios drivers, to not use the material info if lighting is disabled, which is why your vertex colour metod worked. Now the question is do I keep using materials for this or should I switch to vertex colours to improve performance. Anyhow, for anyone else with the problem of alpha blending not working on IOS when using a material, make sure you have lighting enabled.

Weird!?! I tried building OSG with OSG_GL3_AVAILABLE. Things build fine but I just can't get any rendering at all. First GL 3.x, isn't actually used under Windows, it is still a GL 1.x context that is created at runtime. You have to modify the source code to force the GL 3.x context creation (traits-glContextVersion = string(3.2)).

Re: [osg-users] Camera control in osgvisual
Hi Vijeesh, here is some explanation how the SLOT mechanism works currently: it is a list of SLOT classes. A slot class contains the following members: * string name * double value * string sValue (string value) * enum direction: TO_OBJ | FROM_OBJ * enum type: STRING | DOUBLE If a software module wants to store some values which are directed TO the visual Objects ( e.g. object3_LAT), it searches in this list for the slot with the corresponding name, type and direction and stores the value in it. The object updater for example reads on every update in this slot list for a slot with the appropriate name and read the value to apply it to its own object. This has the the following implications: * Supposed to be very slow if lot's of variables are used: if someone searches in the list, he has to perform many string comparisons. * Only strings and doubles can be stored but no complex data structures ( e.g. cigi containers) My approach with the slots was only a first shot. I would be very glad if we could discuss this, maybe also with other users in the forum. It would be great to construct a more sophisticated and usefull architecture to manage the data of the IG. After that I would implement this solution asap, but currently I have no idea in which direction we should proceed. Thank you!

Using in_vertex does actually work, I had misspecified the binding location. So the following line works // both gl_Vertex and vec4(in_vertex,1.0) work here gl_Position = osg_ModelViewProjectionMatrix * vec4(in_vertex,1.0); Actually this works even if I do NOT call program-addBindAttribLocation(std::string(in_vertex), 0); which is really puzzling me. Weird!?! I tried building OSG with OSG_GL3_AVAILABLE. Things build fine but I just can't get any rendering at all. First GL 3.x, isn't actually used under Windows, it is still a GL 1.x context that is created at runtime. You have to modify the source code to force the GL 3.x context creation (traits-glContextVersion = string(3.2)). The context is then created fine but after that nothing on the screen when running my modified sample. I always get an error when calling glUseProgram even though the program linked fine. Still blocked... any help appreciated... -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=38005#38005 ___ 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

Sorry, ignore previous post. I misread your email. Did you inadvertently disable OSG_MSVC_VERSIONED_DLL in CMake?

DAE OBJ FBX 3DS Some of those formats are fine others i'm not sure about. DAE, if you can find the dependencies built for IOS then no probs as I think you build OpenCollada yourself OBJ, this plugin has no dependancies so should be fine (I think i've used it in fact and just built fine on my machine) FBX, i'm pretty sure this is a no show as you have to use prebuilt libs, which at the moment don't include IOS 3DS, again no dependancies so should be fine (just built fine on my machine) For features like skinning etc which you might be using DAE or FBX for, I have been converting them to osgb to avoid having to build the plugins on every platform.

I suspect you are trying to make things more complicated than they really should be, seemingly trying you best to break the OSG, rather than just let it gone with what it's designed to do. Well that came across a little harsh. I have no doubt that my troubles stem from me doing something incorrectly due to my ignorance (extremely little experience with OSG). So we both agree the problem is my fault, hopefully together we can find the cause? I didn't think my setup was overly complicated and I thought I was staying out of OSG's way. These are the steps I went through to get where I am now... 1.) Downloaded the OSG 2.8.3 source code. 2.) Used the CMake GUI to generate a make file for OSG. 3.) Ran make to build the OSG libraries and executables. 4.) Copied the OSG libraries, headers, and executables into a pretty standard ThirdParty directory in my project (that directory's structure was described in my first post). 5.) In my projects CMake I specify where that OSG ThirdParty directory is and I specify that my project depends on OSG (the CMake statements that do this were also in my first post). 6.) Used CMake to generate a make file for my project. 7.) Built my project without error using make. 8.) Ran my application and OSG said it couldn't find the FLT plugin. 9.) Tried adding OSG's lib directory to LD_LIBRARY_PATH but that just caused my application to crash. I view those steps as being pretty standard and simplistic but clearly I'm doing something wrong. hopefully something sticks out as being obviously incorrect. robertosfield wrote: We can only guess what this might be as you explanation of what you have done doesn't provide enough useful information.

I have not run make install, only make. I'm hoping to keep OSG on a level that is local to my project (as opposed to a system level). I'd like to take my project's source code and third party dependencies and check them into SVN. Then a developer can checkout that repository to a local directory and build it without having to make any system level changes...everything is kept local to that checkout folder.

I have a line trail that I make as the object moves along the screen. The line is determined by the user but can have 100 to 200 points that make it up that can be many kilometers long. Every cycle I add a new length to the line and tale one away. I do this by adjusting the vertex array that I added to the geometry at the start. After I make the changes to that, I call the dirty bit to refresh that. I also have a color array that I have set to a color. I grab that array and reset the color for that array (at the 0 point where I first set it) and I call a dirty bit on that. I also do the same for the Normal array but I use a saved setting of the normal (the normal never gets changed) and I call a dirty bit on that. All this changes the position of the line and the line snakes happily along the path of the object. The problem was that the color had issues changing! If a changed the color to black( 0.0,0.0,0.0,1.0) or white (1.0,1.0,1.0,1.0) it’s OK, but if I do a gray (0.6,0.6,0.6,1.0) I would get a white. If a force the normal array to be a double and use something like (0.01f,0.01,1.0f) and the color is set to gray I would get that color.

Re: [osg-users] [osgPlugins] Can't get OSG to load an OpenFlight file.
You should be able to see in your Notify output, it's clear that OSG isn't including your OSG bin directory in its search path. If I recall from your OP, that path is something like: ThirdParty/Linux.x86_64.gcc4.4/OpenSceneGraph-2.8.3/bin If this directory is not in your PATH, then it's odd that *any* OSG executables even run, such as osgversion. You should add it, of course, as you would add any package's binary directory to your PATH. (This is *nix 101, and not specific to OSG.) If that directory is already in your PATH, then it's mysterious that OSG doesn't include it in its search. You could set a breakpoint in osgDB::findLibraryFile to see why it's missing this directory, or just look at the source. -Paul On 3/29/2011 11:03 AM, Ed LaFave wrote: Paul Martz wrote: I believe you have a version problem on your hand.

Re: [osg-users] OSG Stereoscopy (2)
Hi Mukend,
If you are creating your own viewer cameras and associated graphics
contexts then you don't need to call any of the setUpView*() methods,
otherwise you will just end up with the windows and camera it creates
and the ones you create.
Also when you are not using quad buffer stereo the draw/read buffers
of the camera should just be set the GL_BACK.

Re: [osg-users] Camera control in osgvisual
Most of the IG industry uses CIGI to pass data from the host to the IG (and back for end of frame and mission functions stuff). I'm sure the architecture is well defined on this. For starters, you can take a look at Boeing's Multi Purpose Viewer software which is an IG test bed for the CIGI protocol. They interface it to a generic host. The Multi Purpose Viewer uses OSG on the backend for rendering. This might give you some ideas on what you can do to add CIGI into your IG stuff... -Shayne -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Torben Dannhauer Sent: Tuesday, March 29, 2011 6:45 AM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] Camera control in osgvisual Hi Vijeesh, here is some explanation how the SLOT mechanism works currently: it is a list of SLOT classes. A slot class contains the following members: * string name * double value * string sValue (string value) * enum direction: TO_OBJ | FROM_OBJ * enum type: STRING | DOUBLE If a software module wants to store some values which are directed TO the visual Objects ( e.g. object3_LAT), it searches in this list for the slot with the corresponding name, type and direction and stores the value in it. The object updater for example reads on every update in this slot list for a slot with the appropriate name and read the value to apply it to its own object. This has the the following implications: * Supposed to be very slow if lot's of variables are used: if someone searches in the list, he has to perform many string comparisons. * Only strings and doubles can be stored but no complex data structures ( e.g. cigi containers) My approach with the slots was only a first shot. I would be very glad if we could discuss this, maybe also with other users in the forum. It would be great to construct a more sophisticated and usefull architecture to manage the data of the IG. After that I would implement this solution asap, but currently I have no idea in which direction we should proceed. Thank you!

Re: [osg-users] OSG Stereoscopy (2)
Hi Mukund, camera-setDrawBuffer(GL_BACK_LEFT); ... camera1-setDrawBuffer(GL_BACK_RIGHT); I'm pretty sure you can't use GL_BACK_LEFT and GL_BACK_RIGHT if you're not in quad buffer... You need to use GL_BACK for both. That probably explains the OpenGL error. Also, if you have a scale in a matrixTransform, you need to use GL_NORMALIZE or GL_RESCALE_NORMAL in your node's stateset, otherwise you'll be using non-unit normals (the normals are also scaled by the modelview matrix). That probably explains the black cow. // right after object-setMatrix(s * m); object-getOrCreateStateSet()-setMode(GL_NORMALIZE, osg::StateAttribute::ON); Finally, for your 2 windows, well you're using setUpViewInWindow() which creates one window, and you're using osg::GraphicsContext::create() which creates another one. The viewer's main camera is rendering to the former, and your 2 slave cameras are rendering to the latter. You could just remove setUpViewInWindow(), and set the same graphics context for the viewer's main camera as the other 2 cameras (viewer.getCamera()). Note that in your current setup, you have another problem, which is that both slave cameras render to the same graphics context but by default they will both clear the color and depth buffers. If you do it as I said above, the master camera should have no scene data, but should clear the color buffer. The two slaves should have the same scene data, and should both clear only the depth buffer. Have a look at the examples to see how this is done (setClearMask(...)). Hope this helps, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.dyndns-web.com/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Node Nomals effecting color in line Primitives
Hi David, On Tue, Mar 29, 2011 at 7:39 PM, David Glenn david.e.glenn@navy.mil wrote: I have a line trail that I make as the object moves along the screen. The line is determined by the user but can have 100 to 200 points that make it up that can be many kilometers long. Are you seeing precision issues on the data? Every cycle I add a new length to the line and tale one away. I do this by adjusting the vertex array that I added to the geometry at the start. After I make the changes to that, I call the dirty bit to refresh that. I also have a color array that I have set to a color. I grab that array and reset the color for that array (at the 0 point where I first set it) and I call a dirty bit on that. I also do the same for the Normal array but I use a saved setting of the normal (the normal never gets changed) and I call a dirty bit on that. Perhaps the update is going astray. Trying perioidically outputing the line to a .osg/.osgt or .ive/.osgb file and then have a look at the data in osgviewer. Is the colour problem still aparent. I'd also suggest switching off display lists for the data, as it sounds like the data will be small enough to not cause problems with downloading every frame. Another thing you could try is try doing a fixed length vertex/normal array and use a DrawArrays setting to pick out the required length of vertices for the line. Another tweak would be to modify the vertex/normal you require at a position incremented each addition and grow the DrawArray length till it hits the maximum length of line you want in the array, then let the line wrap around by creating two DrawArrays. This approach would allow you to just update a single vertex and normal on each update. The problem was that the color had issues changing! If a changed the color to black( 0.0,0.0,0.0,1.0) or white (1.0,1.0,1.0,1.0) it’s OK, but if I do a gray (0.6,0.6,0.6,1.0) I would get a white. If a force the normal array to be a double and use something like (0.01f,0.01,1.0f) and the color is set to gray I would get that color. I really can't guess why using doubles might make a difference to the colour, it simply doesn't make sense as OpenGL will be casting everything down to floats for the graphics card anyway, and normals really don't require that level of precision. If would suspect anything then it'd be a memory error in managing the arrays, Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [osgPlugins] Can't get OSG to load an OpenFlight file.
Hi Ed, You say you are getting a seg fault when the openflight plugin looks like it's loaded, for me this is progress, and if you are getting a seg fault then continue on this path. The next thing you should do is run your application in gdb or similar debugging tool and get a stack trace. Post this strack trace. Without a stack trace it next to impossible to guess what might be the cause. The OpenFlight plugin isn't often picked up as causing crashes so as first guess I'd say it's not the most likely place to look for the cause. The rest of osgDB is also well used by lots of other developers year in year doing what you are in theory supposed to be doing without crashes, so again this isn't the a likely hotspot for problems. The most likely place would perhaps be some code in your application that is assuming that a node pointer is always not null, or always a certain type of node, and end up derefencing a null pointer or similar error. Another avenue to look into is the issue of case in filenames, Windows filesystem is not case senstive, while unices are all case senstive, this means errors in the case of filenames can get overlooked when developing under Windows but under Linux and other OS's the files aren't located as the names aren't recognized.

Re: [osg-users] [osgPlugins] Can't get OSG to load an OpenFlight file.
Paul Martz and robertosfield, thanks for your help. In addition to OSG my application has another third party dependency, for the sake of anonymity lets just call it PAIN_IN_THE_REAR. As the name implies PAIN_IN_THE_REAR is absolutely awful and has been a reliable source of head aches for several years now. Normally I would begin debugging any mysterious crash with an eye towards PAIN_IN_THE_REAR. However, in this case I gave PAIN_IN_THE_REAR a free pass because I had only setup the dependency on PAIN_IN_THE_REAR...I hadn't yet written any code that actually used PAIN_IN_THE_REAR. Well it turns out that just removing the dependency on PAIN_IN_THE_REAR fixed all of the problems I thought I was having with OSG. Unfortunately, I will need OSG and PAIN_IN_THE_REAR to play nice together so I will have to continue debugging this. Obviously I'm expecting my problem to be caused solely by PAIN_IN_THE_REAR but if my debugging turns up anything that might be relevant to the OSG community then I'll be sure to follow up with a post explaining what I learned.[/img] -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=38051#38051 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] OSG Stereoscopy (2)
Hi Mukund, Well, could you please tell how i can specify setClearMask() for the master camera? (the viewer) viewer.getCamera()-setClearMask(GL_COLOR_BUFFER_BIT); And then you can remove the color buffer bit from camera. You just need to clear the color buffer once, at the beginning of the render (so when the viewer's main camera is traversed), and clear the depth buffer when rendering each of your slave cameras. Also, i wasn't able to get anaglyphs. Here is the snap: http://img593.imageshack.us/f/73302341.png/ I think ColorMask defaults to all components true. So by setting the red to true in one camera, and the blue to true in the other, you're not changing anything. You need to set green and blue to false in one camera, and red to false in the other (because I think red-blue anaglyph is actually red-cyan, so one eye red, the other green+blue). I think this is all setup code you could have looked at in SceneView. It might not do the anaglyph with slave cameras, but the details like this one are the same, so you would have had somewhere to start from.

it occur with 2.8.3? Please check, thanks.
2.8.3 has the same problem. And I've made some progress now. After
comment the following lines in the osgmovie example:
/*
if (image-isImageTranslucent())
{
osg::notify(osg::NOTICE)Transparent movie, enabling
blending.std::endl;
drawable-getOrCreateStateSet()-setMode(GL_BLEND, osg::StateAttribute::ON);
drawable-getOrCreateStateSet()-setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
}
*/
The movie appears and works well (in both 2.8.3 and 2.8.4-rc2). I
believe that the ffmpeg plugin has already worked but the quad is
totally transparent incorrectly. Hope somebody could help test it
because I'm not familiar to the ffmpeg implementation personally.
