Hi Tony Have you take a look to osg/src/osgPlugins/pfb/* source code ? this plugin load pfb fie in osg, so I think many answers of your question will be there.

Re: [osg-users] Animating Textures
Hi Laurens, I created a osg::StateSetCallback that took a osg::TexMat in the ctor and a delay variable. In the operator () I do a check to see if the delay has occurred and then I do a texMax->setMatrix with some incrementing variables. I then attach the callback to the geometries stateset.

Re: [osg-users] [osgPlugins] ETC1 and other TC format support in DDS plugin
Here is the good news, ETC1 is supported by NVIDIA's binary blob on Linux even though it isn't announced. So it can be tested. I validated this by loading a KTX file (instead of a DDS) file, so the code to handle ETC1 is available but only in the KTX plugin. VC4 (in RPi) announces support, but it isn't live yet. Eric Anholt confirmed this when I talked to him last week. It is coming. Intel announces support, but OSG gives an message that the opengl function isn't supported. So I don't know if this is problem with Intel's driver or in OSG itself. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=64924#64924 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] OSG equivalent of Performer pfSequence
Hi Tony, small note: for what you're doing it might be usefull to take a look at OpenSceneGraph\src\osgPlugins\pfb\ConvertFromPerformer.cpp it has a function to convert pfSequence to osg::Sequence (called ConvertFromPerformer::visitSequence) - seems to me osg::Sequence is a good match.

Re: [osg-users] Transparent Window Application for Windows and more OS
Hello everyone, I succeeded in integrating transparent windows as well on Windows platform than on Linux X11. The only problem remaining is that I wanted to be able to modify the transparency color in a coherent way with the clearColor of the main camera. Is there a way to access the window handler during the (pre)render stage ? I don't want to integrate some platform specific code to the render stage code, but maybe there is a way to register a call to a method of osgViewer::GraphicsWindow implementation ? Once I've treated this problem I will propose it on the submission list with a complete example for Linux and Windows. Thanks for your help, Christian Le 29/07/2015 11:05, Christian Schulte a écrit : Hello everyone, I'm currently integrating in osgViewer the transparency an I'm looking for some advices. I started with the code published by Chris Hidden on the mailing list, and modified it a little bit in order to be able to choose between color transparency (LWA_COLORKEY), or alpha transparency (LWA_ALPHA) or both. The probleme is that it is, for the moment, done during the window creation. What I wanted is to be able to adapt the LWA_COLORKEY whenever the user wants, same for LWA_ALPHA. My questions to the community : Where would be the right place to make these changes (as I need to be able to recover the window handle) ? Do you think that it could be interesting to be able to switch from transparent to non transparent during execution ? Should the color, alpha and activation boolean be added to the traits and be modified through GraphicsWindow class ? Has someone already implemented the transparency for another OS / Windowing System, and if yes could we try to unify the way it is done ? Sorry for all these questions, but as it is my first contribution try, I want to be sure to make no mistake !

Re: [osg-users] OSG equivalent of Performer pfSequence
Hi Tony Maybe osgSim::Animation is what you are after. I think its design originates from the OpenFlight-flipbook animations, so may a look at the openFlight importer is worth a shot.

Re: [osg-users] "LOS" materail query
Hi Mike,
OK, the next complication is probably that the osg::Texture has the
probably unref'd the Image assigned to it after it's download to GL, the
method that control it is in include/osg/Texture:
/** Sets whether or not the apply() function will unreference the
image
* data. If enabled, and the image data is only referenced by this
* Texture, apply() will delete the image data. */
inline void setUnRefImageDataAfterApply(bool flag) {
_unrefImageDataAfterApply = flag; }
This is memory optimization, but... if you want to look at the image data
after it's been rendered you obviously don't want to use this feature. By
default this feature is OFF, but if you run the osgUtil::Optimizer on the
scene graph it can switch it on as a memory optimization.
You can switch it back on using the osgUtil::Optimizer::TextureVisitor see
the include/osgUtil/Optimizer header for the TextureVisitor.
Robert.
