Okay, one last try:
1. Have you tried showing the last mip-level (i.e. avg. lum) in a
separate window so you can check the value?
2. Have you double checked your actual tone-mapping? (say by providing
the average luminance via uniform)?
I'm asking this rather silly questions, because last
Hi
in camera interfaces there are attach method which have parameter to specify
either to generate mipmaps or not for texture rendertarget attachmant, it does
not behave correctly?
Cheers,

Hi Guys
Sorry to raise this again, but I'm currently having the same issue. Basically I
am opening files, doing some bits and bobs to them and reexporting. Just for
completeness I do alter the texture stateattributes, but not in a way I would
think would matter. Here's what I'm doing
Code:
Oops
Sorry, the last attached file had a bad png that the plugin can't load. I
copied over it with a backup after the colors got swapped and forgot to run it
through gimp which seems to sort it.
Also I just tested embedding the image into the osgb file, which worked fine.
Thanks

On viewing a map.ive file (which I converted from .dem to .ive using
osgdem.exe) with osgviewer, the map is being shown with its elevations, but is
completely white. I can't see the raster map which is supposed to be draped on
it. This is in Linux (osg built with the latest git clone).

Hi again,
After thinking about it here is what I think the answer is.
Let's say our polytope intersects two circles (or rectangles) A and B, each at
two points
A1, A2 and
B1, B2
The center point of A1 and A2 is computed, denote by centerA12
The center point of B1 and B2 is computed, denote by
Update your gfx driver and see what happens.
Perhaps you map file is built using an OGL feature your current driver
doesn't support. Maybe NPOT textures or something?

make OSG ignore all keypresses, all keyboard events? Just like this, so it
would not react on S, W or even Escape keypresses

So I've done some more digging and seems I'm hitting a case they may be known
to not work.
So in the function CreateCGImageFromOSGData under the case for GL_BGRA I am
entering the else of the if statement.
if(GL_UNSIGNED_INT_8_8_8_8_REV == osg_image.getDataType()).
In there is this
Hi Sergey,
When I attach a texture to the camera should I specify also the number of
desired mipmap levels?
Code:
slaveCameraLogAveragedLum-attach(osg::Camera::COLOR_BUFFER0,
logAveragedLumTexture.get(), numMipMap, 0, /*mipmap*/true);
In the documentation it is said
The level parameter
Hi,
We have a large app that uses Qt for its 2D UI and OSG for 3D rendering and UI.
So it seemed like a good idea to turn on the Qt-OpenThreads integration by
enabling BUILD_OPENTHREADS_WITH_QT.
However, I discovered that OpenThreads::Thread::CurrentThread() (in
Hi
This parameter allows you to directly attach specified mipmap level of texture
to fbo.
If you just need to render to texture and let it generate mipmaps you should
attach level 0.
You can set desired number of generated mipmap levels by
logAveragedLumTexture-setNumMipmapLevels(numLevels).
Hi,
I'm surprised that QThread::currentThread() can return something else than a
QThread instance.
But if this is really the case, the following should solve the issue :
Code:
QThread* pQThread = dynamic_cast QThread* (QThread::currentThread());
if (pQThread != NULL)
{
QtThreadPrivateData*

The osgvnc example is using this, for instance. See the ViewerBase
