[osg-users] Invisibility Effect with Material Color Problem
Bonjour, I make a shape disappear by setting an attribute Material with an Alpha equal to 0. I would like to animate its appearance. I increase the Alpha value until 1, but the original color of the shape is not back, rather than that I get a metallic color. What should I do ? thanks ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Transparency on Shapes
Hello, I am learning to use *Transparency Effect* on OpenSceneGraph. I don't know if I am doing it right. I have made a video screen capture. I do think that I missed something http://www.youtube.com/watch?v=Kzm_1X55OIM I have multiple shapes. I attached a *osg::Material* attribute to some of them.The third sphere (nearst to the user) is set to be transparent up to 40%. // Enable blending, select transparent bin. stateSet-setMode( GL_BLEND, osg::StateAttribute::ON ); stateSet-setRenderingHint( osg::StateSet::TRANSPARENT_BIN ); // Material osg::Material * _material = new osg::Material; _material-setAlpha( osg::Material::FRONT_AND_BACK, 0.4f ); _material-setColorMode( osg::Material::AMBIENT ); stateSet-setAttributeAndModes( _material , osg::StateAttribute::ON ); // Blending osg::ref_ptrosg::BlendFunc blendFunc = new osg::BlendFunc; blendFunc-setFunction( osg::BlendFunc::SRC_ALPHA , osg::BlendFunc::ONE_MINUS_SRC_ALPHA ); stateSet-setAttributeAndModes( blendFunc ); 1. Have I done it right ?? 2. let suppose I would like to modify the transparency of a Node picked ??? Should I get its material attribute and modify its *Alpha* ?? 3. In case, the video show a small lack of transparency between the two cylinders and the sphere ?? is it normal ?? or I missed the *osg::Depth *attribute ?? Thank you for advance for your help Cheers ps: video http://www.youtube.com/watch?v=Kzm_1X55OIM *--* *M.

Re: [osg-users] why zlib.dll is miising when execute .exe file
Hello Nan Torben, You have to add the *3rdParty bin* to your PATH otherise set the environment variable OSG_NOTIFY_LEVEL to a higher verbosity level such DEBUG_INFO or DEBUG_FP (by default it is NOTICE I think). Cordialement *--* *M. ALJI Mohamed* 2011/3/28 Torben Dannhauer tor...@dannhauer.info Hi Nan, which version of the 3rdParty package have you downloaded? The current version is V5. You have to added your 3rdparty/x86/bin folder to your PATH. It contains the dll dependencies and has to be part of your path to allow osgviewer to find it. The environment variable OSG_3RDPARTY_DIR is not required to run OpenSceneGraph with this package, it is only available to allow CMake to find your 3rdparty package automatically. This makes frequent OSG rebuilds easier.. Thank you!

Re: [osg-users] fbx animation
Hi Josue Morad,
Here is a newbie explanation :
- First time, you need to know that the *osgDB *library provides access
to a lot of 2D and 3D files ( like .fbx ), by managing several *osg *
plugins.
- You intend to use an fbx file, so you need to check if the plugin FBX
reader/writer is correctly installed.
- In second, the following snippet enable to load the scene graph of an
fbx file:
osg::ref_ptrosg::Node root = osgDB::readNodeFile( fbxFile )
- Then, locate the *AnimationManager *you want to use either *Basic *or *
Timeline*, according to your necessity.
[image: a02292.png]
- the best way is to use the design pattern Visitor, already implemented
in *osg::NodeVisitor*.
struct AnimationManagerFinder : public osg::NodeVisitor
{
osg::ref_ptrosgAnimation::BasicAnimationManager _am;
AnimationManagerFinder()
{setTraversalMode(osg::NodeVisitor::TRAVERSE_ALL_CHILDREN); }
void apply(osg::Node node) {
if (_am.valid())
return;
if (node.getUpdateCallback()) {
_am =
dynamic_castosgAnimation::BasicAnimationManager*(node.getUpdateCallback());
return;
}
traverse(node);
}
};
- In the previous code snippet, the *BasicAnimationManager*, if it is
found, will be stored on the variable* '_am' *located at *finder._am.*
- in your main function:
AnimationManagerFinder finder;
root-accept(finder);
- then you can recuperate the *AnimationList* avalaible in your fbx file
like this:
const osgAnimation::AnimationList animations =
finder._am-getAnimationList();
- Finally, you can do what ever you want: play the animation on the *
osgViewer*, get the *Duration*, the *StartTime*, the *Name *of the
animation... specify the *PlayMode*..
finder._am-playAnimation( animations[an].get() );
...
std::cout name animation: animations[an]-getName() std::endl;
I hope I helped :) please feel free to respond to this topic to ameliorate
it.
Have a nice day*

Re: [osg-users] osgAnimation : correct approach to detect when a skeletal animation has completed ?
Hello, What about using *isPlaying() *method of your current animation ? does it fulfill your needs ? cheers *--* *Mohamed ALJI* Élève ingénieur en Informatique troisième année à l'ENSEIRB-MATMECA (Institut Polytechnique de Bordeaux - IPB) Webmaster bénévole de l'association L'eau du désert: www.l-eau-du-desert.com 2011/3/3 Thomas Hogarth thomas.hoga...@gmail.com Hi Adrien I've never actually done this but I have thought about it as I'll need it eventually. I think your best bet is to look at void BasicAnimationManager::update (double time), that is where an animation is played through and were you can detect that an animation is finished. Perhaps you could attach your own simple callback object as the user data for your animations. Then inplement your own Animation manager and call the callback object when an animation with one as it's user data finishes. Let me know how you get on as this would be a useful feature.

How can you save your FBX file with multiple animations? I'm using 3DS Max 2010 and I do not see a way to save multiple animations. I'm not familiar with modeling ... I need to do something similar at the moment. I know MotionBuilde can export fbx with multiple takes, but 3ds max can not. I plan to write a node visitor that will find and split any osg animations into multiple takes. Perhaps using a config file. Shouldn't take long, I'll send you a copy when I'm done. If you export your fbx from osg as a .osg file you can see how the data is stored and looks petty straight forward to split it. Alternatively you can use MotionBuilder and I know the FBX plugin is capable of loading the multiple takes.

The FBX model that I’m using has a unique sequence of animations, called “Take 001”. The sequence includes a walk, stand, and run animations. Is there a way to specify that from frame 0 to 100 I have the walk animation, from frame 1001 to 3000 I have the stand animation, and so on? I’m using the AnimationTimelineHandler, as in the example, but I could not figure out how to do it. I play the entire sequence of animations, but I cannot separate them. -- Renato Silveira (Ph. D.

Re: [osg-users] Problem with setProjectionMatrixAsFrustum()
this is a test ! thank you 2011/2/2 Jean-Sébastien Guay jean-sebastien.g...@cm-labs.com Hi Mukund, So, my first query is clear. Well as for my second one. How is it the object is being projected if it is even placed before the near-clip plane? ie before 1900? i could not get this part. Do you have a camera manipulator attached to your viewer? Even if you don't create one yourself, some usage models of osgViewer will create a TrackballManipulator for you. Whether the object is in view does not just depend on the projection matrix, it also depends on the view matrix. If you set up your projection matrix like you said, but your view matrix is identity except for a translation by (0, -2000, -1000), then you will still see your node. And by default, on first frame, the default camera manipulator will do just that - change the view matrix so that the whole scene is visible... So if you want total control over camera placement and projection, remove the camera manipulator. And if you want to see why your node is visible, check the view matrix of your camera after a few frames in the debugger... 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 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
