[osg-users] Obsolete osg-users archive search index?

Re: [osg-users] Obsolete osg-users archive search index?
Hi Emeric et. al, Curious, I have never noticed that the fact the search index isn't updated regularly. I don't recall anyone else highlighting this either so I guess we've all just overlooked it. I have just had a search through the mailman admin pages and can't find any controls for how often the search index is updated. I wonder if this went astray when we moved the mailman server over to dreamhost. I have to admit I'm not a mailman expert. Thoughts from others? Robert.

[osg-users] [osgPlugins] imageio plugin memory issue.
Hi, while profiling my iOS app I noticed that when I load a model with a texture memory grows up to 130MB, after a while it drops down to 64MB and even if I release the memory of the whole scene graph (I dealloc the whole ViewController that hosts all the osg stuff...) those 64MB remain allocated on the heap. Using the Instruments tools I found out that the responsible for that allocation is this function: osg::Image* CreateOSGImageFromCGImage(CGImageRef image_ref); Anyone having the same issue? Any suggestion about a possible solution? I used the latest OSG developer release (3.3.1) and also the stable release (3.2.0). Thanks.

[osg-users] OpenThreads, scheduling, etc ... policies
Hi Community
my client found interesting behaviour on OpenThreads under 64bit OpenSuSE
linux. It seam none of the calls like setSchedulePolicy,
setProcessorAffinity and setSechedulePriority of OpenThreads::Thread are
working. After running a code, they all return 0 (success) but after
inspecting the threads in some tools, they show they are not set as
expected.
So I gave it a try on Ubuntu 64bit. On my linux box none werle working -
all returned -1 (failure). Attached is simple code from Rui's book that
ilustrate the problem.
Any help is appreciated ! Also, the OSG version tested is 3.3.1

Re: [osg-users] Obsolete osg-users archive search index?
Hi Robert, I'm not a mailman sysadmin at all, but the note says that the index should be refreshed every 24 hours. Is this something hardcoded in mailman or can't find no reference to 24 in the mailman configuration file(s)? BTW, does Saturday, 17 Mar 2012 12:16:45 PDT more or less coincide with the server move?

[osg-users] [osgCompute] Float Texture = unable to register image object (cudaGraphicsGLRegisterImage()).
Hi,
I have modified one of the osgCompute examples to try to learn a bit about
osgCompute/CUDA... I am trying to take 3 float textures, and use a CUDA kernel
to create a 4 texture which is a combination of the the 3 input textures. This
works if I create 3 GL_RGBA/GL_UNSIGNED_BYTE textures, btu when I try to use
float textures, using GL_RGBA32F_ARB/GL_FLOAT, I get the following errors:
alloc srcTexture0:unable to register image object
(cudaGraphicsGLRegisterImage()). Not all GL formats are supported.invalid
argument.
unmap srcTexture0: error during device memory synchronization (map()).
alloc srcTexture1:unable to register image object
(cudaGraphicsGLRegisterImage()). Not all GL formats are supported.invalid
argument.
unmap srcTexture1: error during device memory synchronization (map()).
alloc srcTexture2:unable to register image object
(cudaGraphicsGLRegisterImage()). Not all GL formats are supported.invalid
argument.
unmap srcTexture2: error during device memory synchronization (map()).
alloc trgBuffer:unable to register image object
(cudaGraphicsGLRegisterImage()). Not all GL formats are supported.invalid
argument.
unmap trgBuffer: error during device memory synchronization (map()).
Can someone help me out and tell me what i am doing wrong here?
