[osg-users] OpenSceneGraph-3.5.5 developer release tagged

2016-10-07 Thread Robert Osfield 
Hi All,

Today I merged the openthreads_affinity_mask branch into git master,
merged some submissions that included build and bug fixes and made a
few of my own build and bugs fixes as well.  Finally item of work for
me today was tagging the 3.5.5 developer release.

As usual you can find it on gitjhub:

https://github.com/openscenegraph/OpenSceneGraph/tree/OpenSceneGraph-3.5.5

The big changes in this release relate to OpenThreads with the
addition of a new OpenThreads::Affinity class.  This enable finer
grained control of processor affinity.

OpenThreads::Affinity support has also been rolled into osgViewer and
osgDB::DatabasePager to able more user control of what threads have
affinity with what sets of processors.

Not long till stable 3.6 now, the only major change left to merge is
the VAO support.

Cheers,
Robert.

Hi Remo,

Could you please test OSG git master or the up coming 3.5.5 dev
release as they include a fix for the install error issue with VS.

Cheers,
Robert.

[osg-users] Looking for best practice about Shader and memory management

2016-10-07 Thread Valerian Merkling 
Hi,

Now I am able to play with OSG and shaders, I would like to know what the best 
"way" to manage shaders in OSG.

I recently had a problem with re using openGL contexts and missing some 
releaseGLObjects call, so I know I need to be careful.

I have One application, with one composite viewer.
I have multiple views opened (osg::View rendered in a osgQT::GLWidget, and it's 
own scene)

Now If I want, in my case, draw flat squares, and paint some stripes on some 
squares, I use a shader for the stripes.

My question could be : how many instance of osg::Program shall I have for my 
stripes ?

Only one for all the application ? But how can I clean it from the openGL 
context when I close the application ?

One for each view ? And I should call releaseGLObjects when I delete the last 
striped square ? 

One for each striped square ? 

Or shall I just get one big osg::Program with every shaders and use uniform to 
choose which to use ?


Thanks for your help !

Cheers, 

Valerian

Re: [osg-users] Vector script out of range

2016-10-07 Thread Robert Osfield 
Hi Uma,

I have load the h.obj and trail.3ds files under linux without problems
using OSG git master.

As Laurens suggestions it may be making sure that you are building
your own application with the same setting settings a the OSG version
you are linking to.  When setting paths to the plugins it's also worth
setting the path to the parent directory of the plugins other than the
plugin directory itself as the OSG appends a version number to the
plugin directory so when you link to different versions of the OSG it
can choose the correct plugins directory to avoid problems with mixing
dll's.

Robert.

Hi Uma,
This seems like a new problem to me.
First question - are you sure you link the debug version of your program to
the debug osg libraries?
Regards, Laurens.
