Thanks Robert,
I am not calling glGenBuffers() in my code. I am calling the following :
Code:
osg::GLBufferObject *glBO =
vbo-getOrCreateGLBufferObject(osgCompute::GLMemory::getContext()-getState()-getContextID());
Since i am getting undefined behavior, i used the debugger to get inside
Thanks Robert. How could I overlap the two views? Looking at osgcompositeviewer
example it seems they can overlay but one rectangle hides others while I need
the 2D teack background to be transparent.

Hi Robert,
thanks for you reply.
I am pretty sure that the settings did not change. But what i noticed is that
the build is running better when libc++ and the c++11 standard is used when
compiling.
Currently if there is a clang compiler, the standard used is still c++98. This

Hi Jan,
Curious, I had linking errors when compiling osg with c++11 for IOS, so I added
the c++98-flags to cmake. The best we can do is to make it configurable via
cmake.

Hi Sajjadul,
As I said I don't know what is going amiss in your code. Debugging this
type of thing really requires a proper overview of all the code and ideally
testable code. This level of support is something I can provide.
Perhaps if you can't manage the wiring up of OpenCL and the OSG
Hi Robert,
there's just one thing I don't like of this approach: the viewer is the driver.
In my application I have one scene and I attach the root node to the viewer at
startup. Then every model (xml) I load builds its own osg sub-graph and is
attached to the scene. So that code doesn't need

Hi,
How to have view dependents effects on a multiple view render ?
Let us say that I have two views on one scene (split-screen), each view
following a different car in a racing game. Reflection Mapping (RM) has to
be applied to the current car on each view and disabled for all other cars.

Thank you again Robert!
If I undarstand correctly, then I have to create a composite viewer with a
proper view for a 2D track even if the user may not need it (i.e. 2D track
object not loaded). That would not be a real problem.
But on the other hand a user can load more then one 2D track object
Hi,
I tried --compression flag and --compression-dxt1 flag in OSGDEM. However,
when I step through OSG when I view the IVE, I noticed that the texture
compression all defaults to SCTC-DX1. The size of the compiled textures are the
same.
Can anybody advise on how to select the ARB

Hi Jimmy,
I don't recall the options or whether compressed greyscale is possible with
VPB/osgdem as it's a while since I worked on the code. What may be the
best thing to do is simple disable compression, the option is probably
---no-compression.

HI Deniz,
On quick review I couldn't spot the problem, but have a look at the osgtext
example, it has code for placing text on a HUD and should be roughly what
you are after.

I am get a lot of frustration trying to disable frustum culling with OSG

I am setting the perspective matrix to a near plane of 0.1 and a far plane

Hi julio,
I guess you are not looking for culling, but for near-far plane calculation.
try:
camera-setComputeNearFarMode(osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR);
why do you want to disable culling, or did you just mixed it up with the
near-far mode?
cheers

It's often desirable to disable culling for any geometry that is
non-spatial in nature. Such geometry is very common in modern graphics
programming.
Even after you disable near/far auto-compute, and set culling disabled on
your scene graph, the CullVisitor will still cull any geometry that is
