Re: [osg-users] Resetting buttonMask of GUIEvents
Hi Peter, On 8 October 2014 17:35, Peter Bako osgfo...@tevs.eu wrote: Hi, What is the best way to reset the button mask (no button is pressed)? I tried to use Viewer-getEventQueue()-mouseButtonRelease(1,1,1); but this doesn't reset the button mask. The problem is that sometimes the users press more mouse buttons at the same time and release it out of the graphic area, so OSG doesnt get the release event. Then on mouse move the scene is dragged or zoomed, depending from button. It can be stopped only by pressing this (right or middle) button again. And this is confusing. I want to reset this in code, when the user presses ESC key. Do you have any suggestion how to do it? The button mask state is stored in the osgGA::EventQueue::CurrentEventState property that you can get access to via eventqueue-getCurrentEventState(). You can directly set the current state there. Each GraphicsWindow has an EventQueue, this is where the events are placed when the OS's windowing system generates events.

[osg-users] Issue with StateSet::setUpdateCallback and Drawable
Hi,
I have some code where I would like to adjust some attributes in an update
callback on a StateSet. When I tried to test my code, it worked in several
tests but not on others, and I spent some time debugging my code to figure out
what I had done wrong.
It turns out that in osg 3.2 (and in trunk) that update callbacks are not
supported on StateSets that are attached to Drawables.
There's some code in StateSet::setUpdateCallback that is commented out:
Code:
osg::Drawable* drawable = dynamic_castosg::Drawable*(*itr);
if (drawable)
{
//drawable-setNumChildrenRequiringUpdateTraversal(drawable-getNumChildrenRequiringUpdateTraversal()+delta);
}
Uncommenting that line fixed the issue, but I have a couple of questions I am
hoping someone can answer:
1) I couldn't see anything in the source files history on git indicating why
this line was commented out, but I assume there was a reason. Anyone know why?
2) Does anyone know why StateSets only support a single update callback when
other classes support multiple callbacks (with addUpdateCallback instead of
just setUpdateCallback)?
Thanks,
Damian

[osg-users] avatar animation
Hi guys, I'm new in OSG and I have a question. I have a 3D model (avatar) in FBX format, and I'd like to move the model arms. The movement of the shoulders, and wrist seem fine, but the hands/finger don't move. I figured out that the hands have, each one, 15 bones (3 bones for each finger) + one bone for the parent - hand. I multiplied the matrix of each bone for its parent (hand rotation matrix) and after I applied in the model with: bone-setMatrixInSkeletonSpace(boneTransforms[num]*bone-getMatrixInSkeletonSpace()); But, the all hand still doesn't move. Did I do something wrong? Or I missed something?

[osg-users] Access loaded model's textures.
Hi, I am new to OSG (and rusty with GLSL) and am having some problems, I hope someone can help since I cannot find any posts about it. It is a bit difficult to explain, I will do my best: - I have two models; one .flt (a tank) and one .3ds (a plane). - Both have multiple textures to cover the entire model. The .flt model has two different sets (one normal and the other a heat map). - The models are loaded into an osg::Node via osgDB::readNodeFile. - They display fine via the default render setup. Now I want to write a custom shader for some special effects. Somehow for each model the textures are already bound to the shader, without any coding from my side. I can access them by declaring a uniform sampler2D in the fragment shader and calling texture2D(samplerName, gl_TexCoord[0].st). The models display fine via this method. So even though I index one texture I am rendering all the textures from a set. I cannot figure out how to access the other texture set of the .flt model in the shader. Additionally I cannot find any textures in the nodes in normal code; getTextureAttributeList returns zero size. So how do I do this? Also I would like to know how it is possible that the shader renders all the textures in a set while only indexing one, does OSG automatically combine them into one texture during import? Thank you in advance!

[osg-users] multi-thread of osgviewer on Android
Hi, I am new to OSG and have developed my own osgviewer client on Android OpenGL ES 2.0 based on osgAndroidExampleGLES2. Now I want the osgviewer of android to access network files like http:// by curl plugin. However I found a big problem of it: when the network transmission time is too long, the FPS of my app is too slow, less than 1. I think it is because it is a single-threaded client, http curl will block the rendering. Through the online docs, http://www.openscenegraph.org/index.php/documentation/platform-specifics/android/43-building-openscenegraph-for-android-3-0-2, the Android viewer does not support multi-thread. So I only use:_viewer-setThreadingModel(osgViewer::ViewerBase::SingleThreaded) in my code. How to solve my problem? Is there a very elegant solution of it?

Re: [osg-users] osgAndroidExampleGLES2 can not drag and zoom the model cow.osg.
Hi, Sergey First thanks for your reply. I have solved this problem :) Sergey Kurdakov wrote: Hi Xia, for loading cow.osg there was answer - there is need to write your own loader, which will pass textures to respective shaders to save osg models in OpenGL ES 2.0 friendly format there is a write plugin https://github.com/cedricpinson/osg/tree/master/src/osgPlugins/osgjs (https://github.com/cedricpinson/osg/tree/master/src/osgPlugins/osgjs) but you would have to write a loader yourself though older files from https://code.google.com/p/hogbox/ (https://code.google.com/p/hogbox/) - you can retrieve older versions of files via source control app, as new code has little code for loaders, have some hints to help to write your own loader.
