[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 : *

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

If DYNAMIC is a state , I can assume that it is an inherited property. Assuming that can be good solution, I would be sufficient to set it on a root node, isn't it ? (I will not do that of course) Is it different to set it on a Geometry ? or on its Gode / Group / PAT parent ? I'll check is the

Re: [osg-users] osgNV 0.6.2 released, with a preliminary physics support!
