Hi
try to attach depth buffer
pCamera->attach(osg::Camera::DEPTH_BUFFER, GL_DEPTH_COMPONENT32)
or set
pCamera->setImplicitBufferAttachmentMask(osg::Camera::IMPLICIT_DEPTH_BUFFER_ATTACHMENT)
if you use stencil, you need to attach packed depth stencil buffer instead. If
you dont need depth buffer
Hiya,
I've been trying to run the osgViewerQt example. I have osg (including
osgQt) built from git. I'm able to use osgviewer without any issues.
When I try to run osgViewerQt, here's the output:
[preet@icarus osgviewerQt]$ ./osgViewerQt cessna.osg

Hi,
To remove heavy in destruction objects (which will free large buffers
and etc.) I use method like in DatabasePager - hold object references
and pass they to another thread for destructing.
But there is one case which cause crash.

Hi,
I am using MFC to display osg volume data. If the sample data is 30 * 30 *
20 voxel, it is quite smooth on rotating the image on viewer. If the sample
data is 350 * 350 * 60 voxel, I can't rotate the image as smooth as before. If
I used higher voxel data, the rotation become very hard
Hi Alex,
The composite viewer can have multiple views of different scene graph on
different windows. Setup the Traits of each separated window and set it to
each view's camera, and setup your scenes with the View::setSceneData()
method.

What is the best way to have multiple windows with different views of the same
scene graph? I took a look at the composite viewer example, but it has
different views of the same scene graph with a single window. So not quite what
I want.
Thanks.

Hi Ethan,
All you should need to do is attach your osg::Texture to the osg::Stateset that
you are attaching your osg::Program to and then you also need to add an
osg::Uniform to the Stateset for the texture sampler that you use in your
shader program to access the texture:
Code:

Hey all.
I have an OpenSceneGraph tree I'd like to have displayed in QtQuick.
I'd like the user to be able to interact with the scene where the
mouse can zoom/pan/rotate the camera, just like osgViewer allows. I
saw that there were a couple of examples (osgQtWidgets and
osgQtBrowser), but they're
Hi,
I'm attempting to create an osg::Camera that renders to a texture via a frame
buffer object, but it is not working. When I debug it I see that the after
attempting to bind the FBO in RenderStage::runCameraSetup() it checks the FBO
status and it is returned as GL_FRAMEBUFFER_INCOMPLETE_MISSI

Hello all,
I believe that I may have discovered a bug in the GUI abstraction
library; although this may be a known issue. Here are the steps to
reproduce it. I performed these steps on 64bit Windows 7, as well as
64bit Vista, both using version 3.0.0 built in 32 bit on Visual Studio
2008 sp1.

OpenGL FFP lights are point light sources only.
Generally you have to simulate non-point light sources with arrays of
lights (FFP) or a custom shader (GLSL). No examples of either of these are
included in OSG.
What are you trying to accomplish?

Hi
If you use osgParticle for this, both particles and emitter have lifetime in
seconds, which is configurable through their interface. For emitter you should
also call emitter->setEndless(false); as it is endless by default iirc

Hi,
I'm creating an explosion effect with it is fire and smoke trail it is ok but i
want to set a duration that determines how many seconds/miliseconds this effect
will be shown. Does fire smoke and explosion effect classes have such control
or how we can achieve this implementation?
Thank you!

Hi,
I am going through an osg example and one point there is a statement as follows:
Code:
stateset->setRenderBinDetails(-1,"RenderBin");
Commenting the above statement did not make any changes to the scene.
Any explanation when one should call this function ?
Thank you!

Hi Werner
Thanks for the reply. No I'm not using Qt, it's cross-platform at the console
level so I'm relying on OSG's viewer windowing.

Does cross platform mean you are using Qt framework? In this case just
assign a fixed size to the embedding window.
