Re: [osg-users] [osgPlugins] FBX: skinned mesh messed up
Hi Alessandro, thanks for the example. osgAnimation only allows one skeleton per RigGeometry, and the FBX importer assumes that no more than one skeleton will be attached to a mesh, hence the messed up results. Can you explain why multiple skeletons are attached? If the importer merged the skeletons into one would that be OK? Apologies for the delayed response btw, I've switched jobs so I don't have much time to spend on this any more but I'll still try to help occasionally.

I created the model in 3dsMax and noticed that the problem appears if there are 2 bones systems (4 bones) attached to the same mesh and one system is also linked to a dummy object (see the example I'm attaching) - if there is just one system (2 bones) and it is linked to a dummy then the problem does not appear. QuickTime displays the mesh correctly while osgviewer does not (OSG v3.0.0 - FBX 2012 and 2011).

Re: [osg-users] FBX opacity map factor inverted?
Hi Sukender, that does indeed look incorrect. opacityFactor was added by Alessandro so I've not tested it myself. GetTransparencyFactor() has already been used to determine the opacity of the material, so it shouldn't be used again. Alessandro's comment says in practice factor will always be zero and this just tells me all his test models have been fully opaque. I've now removed opacityFactor completely and the RGB of opacityTexture will always be ignored. Unfortunately the FBX documentation is far too vague to say what the correct calculations should be. Can you test if this works for you?

Re: [osg-users] [osgPlugins] Michael Platings
Now we're getting somewhere :) I would ignore the instructions on that page. You will need to build OpenSceneGraph yourself, fortunately it's not nearly as difficult as that page would suggest. 1. Get the OpenSceneGraph source from http://www.openscenegraph.org/downloads/stable_releases/OpenSceneGraph-2.8.3/source/OpenSceneGraph-2.8.3.zipand extract it to C:\OpenSceneGraph 2.

[osg-users] PixelDataBufferObject functions incorrectly named
Hi all, In PixelDataBufferObject::bindBufferInWriteMode() I was surprised to see glBindBuffer(GL_PIXEL_PACK_BUFFER_ARB,...). According to the OpenGL spec Pack refers to *reading* pixels from the GPU into main memory. Is this a bug? The comment for the function explicitly says note: GL_PIXEL_PACK_BUFFER_ARB so I'm guessing it's intentional, and maybe in some particular situation it makes sense. However in the general case the naming is incorrect and has in fact lead me to call the wrong function. If this isn't a bug then to prevent others being similarly mislead I suggest we do one of the following: a) Rename the functions to bindBufferInPackMode/bindBufferInUnpackMode b) Just have one bindBuffer function that takes the target as a parameter. c) Just have one bindBuffer function that uses the target returned by BufferObject::getTarget() Cheers -Michael ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Robert,
I would like to re-raise the issue of uniform array naming, now that it is
affecting me personally :)
To recap:
I have a uniform array in a shader defined as:
uniform bool positions[1];
osg::Program calls glGetActiveUniform() to build a mapping of compiled
uniforms by name. On some systems, the name returned is positions and on
others it is positions[0]. When the latter happens, a corresponding
osg::Uniform named positions will fail since it cannot find a matching
uniform location in the mapping (since it's filed under positions[0]).
I am not convinced that this is a driver bug. It seems more like an
ambiguity. The docs say that the 'uniform location for positions and
positions[0] are the same; they point to the first element of the array.'
(opengl.org/wiki/G...http://www.opengl.org/wiki/GLSL_Uniform#Uniform_management).
I don't see anything that says the value returned from glGetActiveUniform()
must be one or the other.
If both names are valid and equivalent, shouldn't we account for both
possibilities in osg::Program? I suppose you could just alter
getUniformLocation(...) to check for both variations.
Here are the past threads on the topic. The issue crops up on both ATI and
NVIDIA systems.

Re: [osg-users] Incremental Draw?
Thanks J-S, I had the same idea myself but unfortunately OpenGL drivers don't take thread or process priority into account. I made a simple test app that just renders thousands of quads, ran two instances simultaneously, set the process priority of one to high, and the priority of the other to idle, and they both ran at exactly the same frame rate - half the rate of one instance on its own. Thanks for the suggestions Robert. I can't use spacial partitioning in my particular case as there's often a lot of overlapping geometry, but simply splitting the scene graph into many scene graphs with one bit of geometry in each sounds like it could be the way forward.

A simple way could be to run two viewers, each one from a loop running in a different thread? If there is a need to use textures or share resources between the two contexts you can set up sharing between two contexts running in two viewers just as easily as from two contexts running in the same viewer, it's just that you'll have to do synchronization yourself when you need to, because the two viewers will run in their threads independently. Then you could set your principal viewer thread at a normal priority and the other viewer thread at a lower priority, so in theory the secondary rendering should not steal cycles from your main one, but would get the leftovers each frame (if any), so its rendering might go slower (if you're CPU-bound) but that seems OK for you as long as the main rendering goes at 60hz. I don't know enough about your goal to be sure this will work for you, but it's one way to render two scene graphs at different rates.

[osg-users] Incremental Draw?
Hi Robert, is there an equivalent of IncrementalCompileOperation for drawing a scene graph? My precise problem is as follows: In my application I have 2 scene graphs to be drawn concurrently - the primary scene graph must be drawn at a fixed frame rate of 60fps, the secondary scene graph can take a couple of seconds to draw. The problem is that drawing the secondary scene graph interferes with the frame rate of the primary scene graph. Is there something like IncrementalDrawOperation to draw subsections of a scene graph until an allotted amount of time has been consumed, or do you know of a better solution?

Re: [osg-users] Incremental Draw?
I guess I'd better get started on making it then :) The scenes are rendered to FBOs so they're not tied to any particular window/context or display method. The scenario is that a user will set one scene to be rendered and sent to an external display system at 60fps. Once the first scene is rendering the user can request a preview of a second scene. When the preview is ready the user can seamlessly switch the system to rendering and sending the second scene at 60fps. As far as I can see to implement a solution I'll have to duplicate a lot of code from RenderStage/RenderBin, unless you can see a more elegant solution?

As far as I understood, the plugin currently manages to display multiple materials assigned to the same mesh, but if using more than one texture (for example 3 diffuse maps) then it doesn't work: only not-textured materials are displayed correctly while no texture is displayed or only one is displayed if assigned to a particular face).

Re: [osg-users] [osgPlugins] FBX plugin: transparency and reflection maps...
Hi Raymond, I'm not using 3D Studio but the plugin should read FBX files exported from any version of any application. The test I apply is this - if the official Autodesk FBX Quicktime Viewer can view an FBX file, OpenSceneGraph should be able to view it just as well or better. For the majority of files this is true, but if you find any that don't display correctly please let me know and I'll do my best to get it fixed. Cheers!

Re: [osg-users] FBX Plugin: vertex animation support
Thanks for your research Alessandro :) Vertex caches sound like just another way to store morph geometry. osgAnimation::MorphGeometry is just a series of 1 or more geometries (each one stored in a MorphTarget) so in theory it should be as simple as loading each bit of vertex cache geometry into a MorphTarget. I hope it proves that simple! On 9 June 2010 10:24, Alessandro Terenzi a.tere...@gmail.com wrote: Hi, as you know I wanted to try to add the possibility to read vertex animation data from point cache files, so I started looking at existing code in order to figure out where the integrations should be done. I have really basic experience with animations in OSG, so I'd like to share my ideas with you before doing anything. First of all, looking at the FBX SDK doc it looks like that there are 3 ways *geometries can be deformed: using skinning, shapes, or vertex caches. A vertex cache is a way to store directly the vertex animations inside a cache file*. Looking at the existing code in osgfbx, I see that what is managed so far are 'static', 'rigged' and 'morph' geomerty types that I guess correspond to no animations or skinning and shapes deformers respectively. I thought to add also another type (GEOMETRY_CACHE) corrensponding to KFbxDeformer::eVERTEX_CACHE. In the examples provided with the SDK there is the ViewScene example that shows how to load point cache files (there are just 2 functions to use almost in a straightforwar way: PreparePointCacheData() and ReadVertexCacheData()). Well, this is the easy part I guess. But then I don't know how to handle that animation data...of course there are no bones for this kind of animation, also there is just one shape (unlike morphing where I guess at least 2 shapes are required) so I can just think about creating an UpdateCallback that keeps reading animation data (of course loaded once forever outside the application loop) and keeps updating vertex positions. What do you think about this? Can you give me suggestions or point me to other examples that do almost the same thing? Thanks. Alessandro PS: along the ViewScene example there is a sample FBX file (Humanoid.FBX) that I'll suggest you to check, it should contain at least skinning animation, but is not played correctly. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

NURBs - I haven't tested but in theory yes. The FBX SDK provides a function to triangulate NURBs which should get called as necessary and handle everything for us. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

There's no reason why that should be the case as FBX has full support for vertex animation. You're attacking this problem at the wrong point - get on the Max forums and ask how can I export this model so it animates in the official viewer? I agree, but there is also no reason to not support it :) because referring to external pc2/xml files is a feature that is available in the FBX format and so, for completeness' sake, it would be nice to support it in OSG even if there is another way to 'embed' the same cached animations data in the FBX file itself.

Re: [osg-users] Having trouble with basic texture mapping on a 3d object

N don't put a texture in each texture unit. You should only be using
multiple texture units if you need to combine the textures somehow e.g. in a
shader that requires a diffuse texture with a bump map and normal map and
specular map etc...
What you should do is separate your geometry into a different square for
each face of the cube, and for each geometry add a stateset with a texture
assigned to unit 0.
e.g.
for (int i = 0; i 6; ++i)
{
std::stringstream ss;
ss C:\\Documents and Settings\\MTS\\My Documents\\Visual Studio
2008\\Projects\\OSG_test\\Debug\\smiley i+1 .jpg;
Texture2D* tex = new Texture2D(osgDB::readImage(ss.str()));
Geometry* geom = createGeometryForFace(i);//set up vertices and texture
coordinates for a square at the appropriate position
geom-getOrCreateStateSet()-setTextureAttributeAndModes( 0, tex.get() );
geode-addDrawable(geom);

Don't worry, I'm not suggesting anything that will force animations into anyone else's application ;) Personally I have no need for it, but I've recently observed several posts saying Why won't my animations play in the viewer? so to make things easier for newcomers it seems reasonable to add that functionality. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] strange Matrix interface
can somebody explain to me why in Matrixd/Matrixf there is a getRotate, setRotate, getTrans, setTrans, getScale ... but no setScale? is there a reason for this? You could argue that function should be added. However that could lead to people doing mat.setTrans(...) mat.setRotation(...) mat.setScale(...) and then wondering why setting the rotation didn't have any effect (setting the scale would overwrite it). It's probably safest to set up your matrix with pre/postMultTranslate/Scale/Rotate. and why do i have to pass a matrix to the (non-static) bool Matrix::invert method? matA.invert(matB) sets matA to be the inverse of matB. However something that doesn't make sense to me is why to get the inverse of a matrix you have to do Matrix::inverse(mat) rather than just mat.inverse(). PS: a Matrix MatrixTransform::getMatrix (no const reference) would also be nice, so i could operate on the contained matrix directly if i wanted to and would not have to copy it with getMatrix and copy it again with setMatrix...) The MatrixTransform needs to know when its matrix has been modified so that it can set its flags to dirty. If you really need direct access to the matrix for maximum efficiency, and you don't mind setting the flags yourself, you can derive your own class from MatrixTransform. But for most of us the current way is safest. HTH ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] DAE reader - Handling of double precision
domSourceReader doesn't need to create any array until
getFloat/Vec2/Vec3/Vec4/MatrixArray is called. So I suggest adding an
argument to each of those functions specifying a float or double hint, and
at that point if the array hasn't already been created then create it with
the appropriate precision.
e.g.
osg::Array getFloatArray(bool doublePrecisionHint)

Hi all,
I'm working on making Collada (DAE) able to read/write double precision
numbers. Format seems to store floating points values as xs:double, which is
IEEE 754 double precision. So, should I simply convert to float at the time
data is put in geometry (vertices, colors, normals, etc.) depending on
PrecisionHint (See latest submitted osgDB::Options)? The problem is that I
double memory usage for the temporary data. Is this acceptable?
Actually I thought about converting as soon as possible, but it seems DAE
can define data sources without saying what this source is for, and then
reference these sources later, saying that's for vertices, normals, etc.
For now I got an hybrid implementation (not finished yet), which does not
assume anything about DAE precision, and converts at the time data is put in
the geometry. The thing is that I always put double arrays in a strcture
that can handle both float and double arrays... which I find a bit stupid.
Thoughts? Ideas?

Re: [osg-users] strange Matrix interface
m.inverse( m ); ? Don't use it like that as it'll cause an extra matrix copy (see line 614 of Matrix_implementation.cpp). Basically m1.invert(m2); is a more efficient way to express m1 = Matrix::inverse(m2); btw: i am not the only one struggling with the matrix interface, maybe it would be worth the thought of re-engineering it? I agree it's not the most intuitive, but now there's lots of code out there already using that interface so it can't be changed.

Re: [osg-users] FBX plugin with FBX SDK 2011.2
Wouldn't there have been a way to keep it compatible with both? (#ifdefs or something) I would have if I could have without making the code nightmarishly complicated but the structure of how animations are presented by the SDK is very different now. Also, will the new sdk/plugin read older files (that the old plugin read fine)? I guess the answer is yes, otherwise you wouldn't have modified the plugin in that way, but then where does the incompatibility come from? You guess correctly, yes old files read fine :) I should have said the latest SDK breaks compatibility with previous versions* of the plugin code*; there's no break in compatibility with any .fbx files. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Use namespace...
Yes you can, however OSG uses simple names that will likely also be used in other projects (e.g. Array, Node, Group etc.) so it's quite likely you'll get name conflicts if you use another library which uses the same class names. I've had developers making similar complaints to me, so as a compromise we do using somenamespace::SomeClass; using somenamespace::SomeFunction; etc. for things that are used very frequently. That way it will be less of a big deal to change the code if we start using a library that uses the same class names.

I see what you mean, yes all the update() and getValueAt() functions would have to be changed. I don't think this is too application specific to be worthy of attention though.

Re: [osg-users] FBX plugin sets material diffuse color alpha to 0?
Hi J-S, I looked at the model you linked to and all the TransparencyFactor values are 1, which according to the documentation in kfbxsurfacelambert.h means totally transparent - the model has been incorrectly exported. The same thing happened with DAE - Google Sketchup used to export models with the transparency inverted. To deal with that I used a simple heuristic to guess whether the model needed its transparency inverting. I've put the same technique into the FBX plugin, and your model now looks as the artist intended :) ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] osgAnimation and animation mixing/blending
How stable is the current Collada plugin in OSG? It should be very robust now. I've got it displaying all the test models from the https://collada.org/owl/ with the exception of the one that uses morphing (AKA vertex blending). Another issue is that some models assume that they will be rendered with two-sided lighting and without back-face culling, which for OSG isn't the case. However I have no intention of changing this as doing so would compromise the speed of rendering for nicely designed models. Does it support animation well? Yes, all skinned animations should work perfectly, if not then please let me know. And will content creation tools export Collada in a way that osg and osgAnimation will understand? Yes, AFAIK.
