Re: [osg-users] Node to Drawable?

If it's not a Geode, it's probably a Group. Look for the Geode among your Node's children. This approach may be easier if you always load the same model. Jacob Huckaby wrote: Hi, Quick question (at least I hope it is.) I am trying to find the Drawable inside a Node that I read from a file,

[osg-users] Multisampling: How to enable

I have tried to enable multi sampling, but it has no effect. This is how I try to activate it: modelView = new osgViewer::View; modelView-setUpViewInWindow (400, //x 0, //y 640, //width 480); //height

creating graphics windows yourself, you can manually set the number of samples, same applies if you use MFC/QT etc. to create your own graphics windows. Robert. On Tue, Apr 15, 2008 at 2:02 PM, Per Rosengren [EMAIL PROTECTED] mailto:[EMAIL PROTECTED] wrote: Thank you (both)! It works

You probably tried osgViewer::View::setUpViewAcrossAllScreens () if you have one desktop on two screens, or osgViewer::View::setUpViewOnSingleScreen (unsigned int screenNum=0) , one for each viewer, if you have two desktops. If so, what happened? Renan Mendes wrote: Hi, It's been a

Re: [osg-users] HUD with perspective

You have to set both the view matrix and the projection matrix of the camera. The view matrix is the pose of the scene coordinate system in the camera coordinate system. Use voidsetViewMatrixAsLookAt (const osg::Vec3 eye, const osg::Vec3 center, const osg::Vec3 up) and provide it with the

Re: [osg-users] converting .svg to .osg? ... or project from svg to svg

I have used 3dldf (http://www.gnu.org/software/3dldf/) earlier to create vector graphics from 3d models. It would be extremely cool to extend osg to create vector graphics output with an SVG Viewer! Imagine infinite resolution rendering! This would be really difficult, since you can't use depth

Re: [osg-users] Loading an image file

I too need to show images. Since osg is (and should be) 3d-based, the way to do is seemed to be to display a rectange Geometry infront of an orthographic camera, and set the rectangle texture to be the image. Instead of this, I chose to use OpenCV (CV for Computer Vision), but you can also
