Re: [osg-users] Using 'NodeTrackerManipulator' while holding camera steady

[Andrew Cunningham]

Clearly I **am** barking up the wrong tree and should be looking at 
osgManipulators :)

[osg-users] Using 'NodeTrackerManipulator' while holding camera steady

[Andrew Cunningham]

Hi,
I am trying to use NodeTrackerManipulator to rotate a single "node" while 
holding the camera view steady.  That is the NodeTrackerManipulator will modify 
the transform of a single node not the camera viewMatrix. Am I barking up the 
wrong tree here.

Andrew

Re: [osg-users] FBO setup not working..

[Julien Valentin]

Hi,
Strange issue...:/
The first tought  coming to my mind about it is
perhaps default graphic context format provided by ATI driver throught 
Win32WindowingSystem is not DEPTH24STENCIL8 but DEPTH16...
but it's a guess...
Perhaps giving us log with info notify level can be more helpfull to 
diagnose

Cheers

Re: [osg-users] FBO setup not working..

[Rowley, Marlin R]

So I've tracked the error message down to attaching the render-to-target camera 
with the components:

// this doesn't work on NVIDIA/Vista 64-bit
// FBO status = 0x8cd6 (FRAMEBUFFER_INCOMPLETE_ATTACHMENT_EXT)
rttCamera->attach(osg::Camera::DEPTH_BUFFER, GL_DEPTH_COMPONENT);
rttCamera->attach(osg::Camera::STENCIL_BUFFER, GL_STENCIL_INDEX8_EXT);

Is there another way to attach buffer bits to a camera?

I've discovered my problem. I am to blame, nothing broken here. Thanks!

Ahhh, Robert, thanks, that's the trick :-)

Re: [osg-users] Shaders with multiple views using ViewportCallback

[Robert Osfield]

Hi Chritoph,

The right way to do is to to assign an osg::Uniform to each
osg::View's master Camera's StateSet i,e


  view->getCamera()->getOrCreateStateSet()->addUniform(new
osg::Uniform("viewport", osg:::Vec4(x,y,w,h));

[osg-users] Shaders with multiple views using ViewportCallback

[Christoph Dohmen]

Hi all,

I need to use the viewport dimensions for some calculations in my vertex 
shader. The most found way of doing the update of the viewport-size uniform is 
the ViewportCallback derived from osg::Uniform::Callback which encapsulates a 
camera.
But what happens if I have multiple views?
How can I fetch the viewport size in my shader per viewer?

Thank you!

Cheers,
Christoph

Re: [osg-users] Trackball Manipulation Broken?

[Robert Osfield]

Hi Erik,

I am not aware of any trackball problems.  Could you expplain what you
think is broken?  Can you reproduce the bug with osgivewer?  What
platform are you working on?

As a general comment, 3.2.1 is pretty old now.  I am preparing 3.6.1
right now...  I would recommend looking at update to at least 3.4.x or
even better 3.6.x.  Using an update version of the OSG brings lots of
improvements and bug fixes that won't make it into the 3.2 branch.

Robert.
