Re: [osg-users] How to convert osg::Node to osg::Matrix Transformation? It is returning NULL
Hi Goutham, In the code you attach both models to the same matrixtransform, so adding a rotation will rotate both models. To rotate only the cow it will need it's own matrixtransform: change the line mt->addChild( model.get() ); to root->addChild( model.get() ); and the chessna model will stop rotating. Regards, Laurens.

Hi, Is anyone else experiencing problems with the mailing list? 'm haven't been receiving any mails for the osg-user/submissions in a week. Could someone check if I'm still on the list? Thank you!

Re: [osg-users] [forum] Mailing list problems
Hi Sabastian, I haven't seen any problems with the mailing list - posts have been coming and going all week, I haven't seen any admin posts reporting problems either. I have just checked the admin pages to see if you address is subscribed OK and everything looks correct for you, there outwardly doesn't seem to be a reason why you'd not be receiving mail. Could a spam filter be eating up all the traffic at your end? Robert.

Re: [osg-users] How to convert osg::Node to osg::Matrix Transformation? It is returning NULL
HI Goutham, Have a look at the osganimation example, this illustrates loading multiple models and placing each one under it's own MatrixTransform. Robert.

Hi Robert, I've double checked and I simply don't get any emails from the list. I also sent a new request to be added to the list. Could you check if you received anything?

[osg-users] Problem with clearing the stencil buffer
Hello everyone, I'm trying to use stencils and I'm not sure what I'm missing. Basically I have two quads in my scene. I want the quad two to set the stencil buffer to 1, and I want the quad one to be visible only where the stencil buffer is not 1. So far I am getting the result which I want if I don't clear the stencil buffer. Of course in that case when I rotate the scene using the viewer, the stencil buffer gets painted to 1's(because of the quad two) and I don't see the quad one even on places where quad two is not positioned anymore. However when I clean the stencil buffer(see below), I don't get the result that I want. > viewer->getCamera()->setClearMask(GL_COLOR_BUFFER_BIT | > GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT); In this case both of the quads are visible. I'm suspecting that the stencil buffer gets cleared before the stencil check is done. Here is a part of my code where I set the stencils. > osg::ref_ptr transform_one = new > osg::PositionAttitudeTransform(); > osg::ref_ptr transform_two = new > osg::PositionAttitudeTransform(); > transform_one->addChild(createQuad()); > transform_two->addChild(createQuad()); > transform_two->setScale(osg::Vec3(0.5, 0.5, 0.5)); > transform_two->setPosition(osg::Vec3(0.25, 0.2, 0.25)); > > // --- Begin stencil related stuff > osg::ref_ptr ss_one = transform_one->getOrCreateStateSet(); > osg::ref_ptr ss_two = transform_two->getOrCreateStateSet(); > osg::ref_ptr stencil_one = new osg::Stencil(); > osg::ref_ptr stencil_two = new osg::Stencil(); > stencil_two->setFunction(osg::Stencil::ALWAYS, 1, ~0u); > stencil_two->setOperation(osg::Stencil::KEEP, osg::Stencil::KEEP, > osg::Stencil::REPLACE); > stencil_one->setFunction(osg::Stencil::NOTEQUAL, 1, ~0u); > stencil_one->setOperation(osg::Stencil::KEEP, osg::Stencil::KEEP, > osg::Stencil::KEEP); > ss_one->setMode(GL_LIGHTING, osg::StateAttribute::OFF); > ss_two->setMode(GL_LIGHTING, osg::StateAttribute::OFF); > osg::ref_ptr cm_one = new osg::ColorMask(); > // I play with the parameters below to see the position of the quad two cm_one->setMask(false, false, false, false); > ss_two->setAttribute(cm_one); > ss_two->setAttributeAndModes(stencil_two, osg::StateAttribute::ON | > osg::StateAttribute::OVERRIDE); > ss_one->setAttributeAndModes(stencil_one, osg::StateAttribute::ON | > osg::StateAttribute::OVERRIDE); Any help would be appreciated, I am sure I'm missing something really basic :) Thanks ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
