[osg-users] osgText size in screen coordinate problem

Hi, Currently making my billboard node, I add an osgText on it. I need this text to be in node's coordinate, but in constant pixel size on screen. When the billboard move or rotate, the text will follow it. The only thing the text can change is caracter size. I use this code : *

Re: [osg-users] osgText size in screen coordinate problem

Hi Vincent, I've never used osgText in conjunction with osg::Billboard before. I can image the mix of on the fly compute matrices might cause problems. osgText has support for billboard behaviour so I'd recommend not adding the text to the billboard, instead just add it as sibling to the

Re: [osg-users] osgText size in screen coordinate problem

Hi Robert, I did it from the past for a simple OSG text on a billboard node, without constant screen pixel size management and it works well. I'll try to get the text out from the billboard, hoping this won't be so difficult to obtain the same result... Thanks for this explanation. Regards,

Re: [osg-users] osgText size in screen coordinate problem

No. I just want the size of the text to be updated. I would control the position/orientation myself. *osg::ref_ptrosgText::Text d = new osgText::Text; d-setColor(osg::Vec4(NEW_OBJECT_COLOR_TXT,1.0f)); d-setRotation(osg::Quat(-osg::PI_2, osg::Vec3f(1,0,0)) * osg::Quat(-osg::PI_2,
