Hi,
one related question ... does it make sense to call setNode() somewhere in my
NodeTrackerManipulator (with the node following node) so that the home position
is computed wrt that node or is it better to call setHomePosition() explicitly?
Moreover, when the home position would be used?
To everyone using OSG and Qt,
I watched the following demo of someone presenting QML on Raspberry Pi:

... and an interesting idea popped up in my mind: What about creating an
osgQML plugin that can provide texture data through osg::ImageStream?
Hi,
I am wondering if someone ever tried to load 32bit floating point grayscale
.tiff images under Mac OSX with ImageIO. This seems not working at all. This is
a specific problem for grayscale textures.
I tried to change the code in the ImageIO ReaderWriter class but obviously I am
doing
Hi Andreas,
I tried to recreate the problem with your model but haven't seen it
yet. Could you record a camera path that demonstrates the issue and
then post this so that we can test exactly the same thing as you. In
osgviewer you can press 'z' to start recording the camera path then
'Z' to
Hi Robert,
Sure, here is the animation path. I zoom in and out a couple of times in
the end of the path to show where it disappears. I wonder if it might be
related to my ATI graphics card and its drivers...well, let's see if you
can reproduce it first.

Hello.
Is there any way to split the screen in 2 (vertical) ?
I would like to use 2 different cameras at the same time.
thnx.

Have a look at the osgcompositeviewer example.

Hi,
I can load floating-point greyscale diffs via the imageio-plugin, but
they end all as RGBA/unsigned byte osg::Images.
There's definitely some code-paths missing :)

I am creating a custom Drawable that needs to push a Fragment Shader
into the current rendering state and then, after a single extension
call, subsequently remove this shader from the state.
I have some code I noodled through to make this work, but I feel like
there is probably a better way. It
Doesn't a Drawable's state get applied prior to the call to
Drawable::drawImplementation()? If so, you could just put the _program in your
Drawable's StateSet?
It's easy to verify that things are happening in the right order using a
debugger with breakpoints set at your drawImplementation()

Hi Robert,
Thank you, that did the trick. The latest ATI drivers didn't work with
display lists either. So it seems NVidia is still superior with OpenGL
compared to ATI, as always...

Hi Jeremy,
It should be possible to do a

state.apply(stateSetOne);
// do stuff

// do more stuff

I enable the program using this:

and i disable it using:

I have used this:

But why the other way didnt work ?

Hi Jeremy,
In the past I've done similar low-level 2-pass rendering in a Drawable,
by doing as Robert suggests. Apply one stateset, draw, apply another,
draw again (same or different geometry).
A Program is just state, so you need to draw something in between
setting different Programs.
