Re: [osg-users] osgFX Outline Patch

Salut Jean-Sébastien, thank you for your advice. I already had the line Code: osg::DisplaySettings::instance()-setMinimumNumStencilBits(1); set as in osgoutline. Just to make sure, I disabled it to see that the line does not make any difference... Then I noticed how osgViewer::View feeds

Re: [osg-users] update problem

I found that the NodeVisitor has a getFrameStamp() method but I really don't understand how to use the getReferenceTime() or getSimulationTime() methods of the returned FrameStamp. Which is the difference between them (they seem returning the same value)? Which is the unit of the returned

Re: [osg-users] update problem

HI Gianni, The ReferenceTime is the elapsed actual time in seconds, while SimulationTime is the time that physical simulations/animations should use - by default SimulationTIme will be the same as ReferenceTime, but you can override this to speed up or slow down the animation speeds. Calling

Re: [osg-users] update problem

Thanks Robert. I found in a previous thread of the forum that the simulation time can be set by the viewer.frame() call. In that call I pass my simulation time (got from my animation manager), so I can get it from the NodeVisitor in the UpdateCallback and it works fine. Anyway I didn't get

Re: [osg-users] Update callbacks and LOD

Hi, To my mind there are two solutions : 1. You put your callback on the LOD child you want, so when the child will be hidden by a upper-detailed level child, the callback should not be traversed 2. in your callback you check if your node is still active, and if not, just do nothing.

Hi Bob, SceneView is low level osgUtil class that knows about osgGA or any of it's event handlers, so it's not really not a case of making event handlers work with SceneView. Instead you should be thinking about adding event handlers to your own custom viewer code, or... just use

Hi Frank, You can share a single osg::Vec3Array between multiple osg::Geometry, in the lastest OSG in svn/trunk and the 2.9.x dev series the buffer object support should also be flexible enough for you to manually specify the VBO for that particular Vec3Array. Robert. On Wed, Sep 8, 2010 at
