Re: [osg-users] Keep Geometry always visible withtout occlusions

[Jannik Heller]

Hi,

Indeed, the depth attribute is the way to go. You also need to set a high 
RenderBin number to make sure that the object you don't want occluded is always 
rendered last:


Code:

mygeometry->getOrCreateStateSet()->setAttributeAndModes(new 
osg::Depth(osg::Depth::ALWAYS), osg::StateAttribute::ON);
mygeometry->getOrCreateStateSet()->setRenderBinDetails(1000, "RenderBin");




Cheers,
Jannik

Hi,

you can add Depth attribute to your fat vertex with ALWAYS set as a depth
test

something like

mygeometry->getOrCreateStateSet()->setAttributeAndModes(new
osg::Depth(osg::Depth::ALWAYS), osg::StateAttribute::ON)
