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?

Could a spam filter be eating up all the traffic at your end?

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.

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.

[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_ptrosg::PositionAttitudeTransform transform_one = new osg::PositionAttitudeTransform(); osg::ref_ptrosg::PositionAttitudeTransform 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_ptrosg::StateSet ss_one = transform_one-getOrCreateStateSet(); osg::ref_ptrosg::StateSet ss_two = transform_two-getOrCreateStateSet(); osg::ref_ptrosg::Stencil stencil_one = new osg::Stencil(); osg::ref_ptrosg::Stencil 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_ptrosg::ColorMask 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
