[osg-users] How to force FFMPEG plugin

Does anyone know how to force the use of the ffmpeg plugin instead of xine. I know that this is possible on the commandline, eg: osgmovie -e ffmpeg movie.mov But I'd like to do this in code, eg: osg::Image* image = osgDB::readImageFile(path); osg::ImageStream* imagestream = dynamic_cast(image

CERTI? (http://www.cert.fr/CERTI/) - CERTI is a runtime infrastructure for distributed discrete event simulations developed at ONERA. It provides a set of services used by simulators to interoperate (such as object management, time management, optimization services, etc.). Using these services help

Hi, I have built a 3D environment (Maze) using 3DsMax and imported into the OSG. I have a basic collision detection implemented with just 2 lines on either side of the user in the environment which detects the intersections with objects. But, as the user navigates in the maze, he is ramming in

Re: [osg-users] osgDB Serialization findings

Wang and others, One other item I forgot to mention that also tripped me up. Be careful with the use of osgUtil::Optimizer with custom serialization classes. Certain nodes (Group, MatrixTransform, etc) can be removed, replaced and/or reordered through optimization. If you subclass any of the

Hi Dave, the former with instancing subgraphs with Transform is really easy. Hope the following snippet will give you the idea: osg::Group* root = ... osg::Node* myModel = . for (int i=0; isetMatrix(osg::Matrix::translate(myPosition)); mxt->addChild(myModel); } root->addChild(mxt); Cheers,

Re: [osg-users] CubeMap-Reflection and ShadowMap don't work togehter?

Have you noticed the new shader composition submission on osg-submission? Might be worth of trying that. If you succeed in it (also, you can do the reflectiopn with GLSL as well, look in the archive, I have posted sample for that), you can post your work as an example of the new shader composition

Robert, Thank you very much for your reply. I will certainly start with much smaller data sets as I move toward my goal. Further your suggestions for the more advanced topics are much appreciated. Its very helpful to know before delving too deeply into OSG, that it can do what I need. Th

Re: [osg-users] CubeMap-Reflection and ShadowMap don't work togehter?

Hi Martin, I am afraid you will have to touch GLSL. All shadow map techniques are shader based. What you will have to do is: replace base texture 2D sampler with your textureCube sampler and will have to process tex coords accordingly. If you have not yet learnded GLSL, this moment have just

Re: [osg-users] Reuse of models without duplication

Hi Dave, The OSG allows you to share subgraphs between multiple parents - in your case it'd multiple Transform nodes, so yes you can do what you are intending to do. However, you mention that you want to create millions of instances and in this case your approach will be inappropriate as the CPU

Go forward. Raknet is networking library - using UDP (performance benefits). UDP disadvantage is that it is sometimes firewalled. If you reach data consistency problems, look for simple solutions... John xyc508 wrote: Thanks John, I am try OSG+Raknet+OpenAL+MFC to develop Distributed Interacti
